START UP HYDROCRACKERSWITHOUT AMMONIA INJECTIONAVOID AMMONIA AND SULFUR INJECTIONDURING HYDROCRACKER Start-upsTOur newest offering, Totsucat HC-AP,combines the patented Totsucat Activation and Sulfiding process with aspecial “acid protection” step, which usesnitrogen to passivate the acidic sites. WithTotsucat HC-AP, the catalyst will besulfided and the acidic cracking sites willCATALYST SERVICESbe protected from hyperactivity that canlead to exotherms. By treating yourcatalysts with Totsucat HC-AP priorto loading, complicated and timeconsuming sulfiding steps are no longerrequired, and the dangers of ammoniainjection can be totally avoided.In a previous start-up of theirhydrocracker, a Midwest refinerexperienced difficulties injecting theproper amount of ammonia into theunit that was needed to passivate thecracking bed. For their 2012 start-up,this refiner selected Totsucat HC-APtreatment for their hydrocracking catalystand combined that with Totsucat N tosulfide and activate their hydrocrackingpretreat catalyst. The Totsucat treatmentenabled the unit to reach normal SORtemperatures within 36 hours of oil inwithout any exotherms.TOTSUCAT PREACTIVATION: Allows thefastest and safest start-up possible.CATALYST RESALE: Why buy freshcatalysts when regenerated catalystswith “like-fresh” activity are available?SPECIALTY REGENERATION ANDREJUVENATION: Get 95% activity fromSpecial Regeneration and/orRejuvenation. Our techniques aredifferent than a simple carbon burn.ACTIVITY TESTING: Don’t just rely onsurface area and poison levels. With twomulti-tube test units, EURECAT now runs82 activity tests per month to measure thetrue catalyst activity at ULSD conditions.SAS SERVICE: Only get the “good stuff”back with our Sample, Analyze, andSegregate Service.PRESSURE DROP TESTING: EURECAT offersPressure Drop Testing at our laboratories inthe US and Europe. This provides you withreal-world ΔP predictions.TOTSUCAT HC-APemperature excursions are always arisk when starting up a hydrocrackingunit loaded with fresh catalyst. Tominimize the risk, ammonia is ofteninjected during the sulfiding process.The addition of extra nitrogen from theammonia passivates the hydrocrackingcatalyst, reducing the risk of exothermsas the cracking catalyst reaches operatingtemperature levels. However, ammoniaaddition exposes operations personnelto a potentially hazardous material andslows the start-up process. EURECAT hasdeveloped a method to eliminate theneed for ammonia injection.
Ammonia injection was not required, allowingthe refiner to start up their hydrocracker withouthandling any potentially hazardous chemicals.HYDROCRACKERSIn these days of high cracking margins, theperformance of hydrocracking catalysts is criticalto the profitability of the entire refinery, makingit crucial that these specialized catalysts aretreated with the greatest of care. Processing»» Load-and-Go reactor start-ups. The activemetal sulfides are totally formed during theTotsucat treatment. No additional sulfidingagents or complex activation procedures arerequired after loading.»» No temperature excursions»» No need for additional hydrogen at start-up»» Minimal sour water formation during start-up»» No odors or HSE issues related to thehandling of sulfiding chemicals and H2S.START UP WITH CRACKED FEEDSEURECAT has also developed an exclusiveprocedure to gently moderate the initialcatalyst hyper-activity of freshly sulfidedcatalyst. This unique process, called Totsucat CFP, allows the direct introduction of cracked orheavy feeds without the 3-4 day delay typicallyrecommended by catalyst manufacturers.Many CFP users have also experienced lowerdeactivation rates by treating their catalyst withCracked Feed Protection.»» Negligible amounts of H2S are releasedduring reactor heat up, protecting sulfur»» Sensitive units downstream and preventinga sulfur overload of your SRU.»» Starting up with Totsucat -treated catalystsis similar to a restart after an emergency shutdown. Start-up time is reduced to a few hourswhile the risk of damaging the catalyst priorto activation is eliminated. The catalyst loadwill achieve peak performance since sulfidingand activation is controlled at very preciseconditions by the patented Totsucat process.TOTSUCAT HC-APPre-Activating hydrotreating catalysts withTotsucat offers many benefits to the refinerincluding:with Totsucat HC ensures that hydrocrackingcatalysts function as designed without theneed to spend valuable production time onin-situ sulfiding. Totsucat N is designed tomaximize the hydrodenitrification (HDN)activity of the newest NiMo catalysts typicallyused in the pretreat section of the hydrocracker.
WILL YOUR REGENERATED CATALYSTBE A THOROUGHBRED AGAIN?The EURECAT R&D Group has a vast amount of experiencewith activity testing on hydro-treating catalysts.Our first pilot plant MDSU was installed in 1996 and was usedextensively to determine the HDS activity of regenerated catalystsas part of our pool management services.As HDS activity testing became essentialto EURECAT‘s customers, our testingcapacity had to again be expanded tocope with the demand. Our response wasthe installation of a Multi-Tube test Unit(MTU) which allows testing of 10 samplesin 10 parallel reactors of 10 ml each.The MTU runs a three condition protocoland has proven to be extremely reliable.Based on this success, a second MTU wasinstalled in 2010, increasing EURECAT’stotal number of test reactors to 22.HORSE TRADINGIf you don’t have a requirement to reuseyour catalyst within your own refinery,having it activity-tested by EURECAT willopen the door to selling it to an affiliatedrefinery or to a third party.EURECAT’s catalyst purchase and resalenetwork is shared between our affiliatesin the USA, France, Italy, Saudi-Arabia andIndia. Our worldwide sourcing effortsassure a steady supply and demand forregenerated catalysts. In addition, thecatalyst pools we manage for severalcustomers are often in under supply oroversupply of exactly the catalyst thatyou may wish to sell or purchase.Contact EURECAT today for a qualifiedregenerated catalyst and buy a racehorsefor a workhorse price.REGENERATION AND ACTIVITY TESTINGThe introduction of low and ultra-lowsulfur specifications for dieselrequired testing with increasingly deepHDS regimes. Two new MIF units werepurchased in 2003 to carry out testing atthese new conditions. The MIF’s are stillused today, one for HDN activity testingand the other for additional R&D testing.
YOU CAN’T JUDGE A HORSE BY ITS COLOR ANYMOREThe introduction of the latest generation Type II and balanced Type I/Type II catalysts has shaken upthe catalyst regeneration universe. Many of these catalysts require post-treatment after regeneration.Unfortunately, the post-regen activity is less predictable using only the data traditionally gathered in aregeneration study such as surface area and contaminant levels. With today’s advanced rejuvenationtechniques, a critical determining factor for catalytic activity is re-dispersion of the active metals. Truecatalyst performance is best measured with pilot plant activity testing.DON’T JUST ESTIMATE THE ACTIVITY, MEASURE THE ACTIVITYEURECAT can measure both the Hydrodesulfurization (HDS) and Hydrodenitrification (HDN) activity of yourregenerated CoMo or NiMo catalyst in our state of the art pilot plants. Expressed as RVA or RWA versus thefresh reference catalyst, the activity value provides you with a sound decision basis.Our standard MTU test protocol measures catalyst performanceULTRA LOW SULFUR DIESEL HYDROTREATINGat 3 different levels of severity utilizing straight-run gasoil(HDS): The majority of the catalysts we test belong(1.2 wt% S) at the following conditions:to the ULSD category, where the investment andoperational risks associated with regeneration andrejuvenation of the catalyst justify an HDS activity640 / 650 /WABT:LHSV:2 h-1test before the catalyst is reused. Activity testing is660 Fan essential and dependable quality control tool,Pressure:580 psiH2/oil:300allowing the transfer and reuse of your catalystbatch within the corporate catalyst pool. EURECATtracks the activity values for various lots in catalystpools we manage for several major refiners, allowingthe customer to carefully manage when and whereeach lot is applied with minimum risk exposure.EURECAT’s extensive database on activity testingcontains a wealth of process and catalystknowledge. A study (right) carried out by EURECATassessed the effects of different contaminants onthe activity of REACT treated KF-757.HYDROCRACKER / FCC PRETREATMENT (HDN): HDN performance of NiMo catalyst in HC-PT or FCC-PTconditions is tested in a dedicated format on LCO feed at an operating pressure of 1450 psi (100 bar).NON-STANDARD HYDROTREATING TEST FORMATS: EURECAT will gladly develop a customized testingprotocol for your specific process or R&D application. Our MIF testing unit is extremely flexible in terms ofoperating temperature, pressure, LHSV, and H2/oil ratio.

With this service, a clearcontamination profile can be developed,enabling the refiner to “cherry pick” thecontainers of catalyst that contain cleanregenerable catalyst. SAS ensures that onlyhigh activity catalyst is regenerated andreturned to the customer, while heavilycontaminated catalyst is quickly sent outfor metals reclamation.
CASE STUDY: SAS FOR A ULSD UNITA complete Sample, Analyze, and Segregate (SAS) service was performed on catalyst from a ULSD reactorsystem with four beds containing a total of 760,000 pounds of CoMo catalyst. The catalyst from the TopBeds of both reactors was vacuumed out, while the Bottom Beds were gravity dumped. All of the bins werenumbered in order as the material was unloaded. This allowed EURECAT to create a contaminant metalsprofile for all of the beds so that the quality of the catalyst from each could be determined.Visual Inspection of 120K lbs CoMoVisual Inspection of 250K lbs CoMoSupportFailFailPassPassRegenerated95% RVAThe analysis showed that about one half of the catalyst in the Lead Reactor Top Bed and all of the Lag Reactor TopBed contained clean catalyst that was suitable for regeneration. Unfortunately, since both Top Beds were vacuumedout, the particle length was much too short for regeneration and therefore all of the material had to be sent formetal reclamation. The Bottom Beds were both successfully rejuvenated, recovering 500K pounds of catalyst withvirtually the same activity as fresh ULSD catalyst. The customer achieved another full cycle with no activity orpressure drop issues after reloading this material.Visual Inspection of 140K lbs CoMoVisual Inspection of 250K lbs CoMoFailFailPassPassSend to ReclaimWHAT IS SASScandinavian Airlines?The Society of Amateur Scientists?Surfers Against Sewage?No, no, and no!SAS is EURECAT’s unique Sample, Analyze, andSegregate service.
