Patent number: 8614160Abstract: Catalyst compositions comprising a siliceous zeolite component, either in separately formed catalyst particles or dispersed in the same binder or matrix as other zeolites of the compositions, are described. The catalyst compositions, for example as blends of three different bound zeolite catalysts, are particularly useful in fluid catalytic cracking (FCC) processes due to the reductions in coke and dry gas yields that allow FCC throughput, which is normally constrained by gas handling and/or catalyst regeneration capacity, to be increased.Type: GrantFiled: February 8, 2012Date of Patent: December 24, 2013Assignee: UOP LLCInventors: Lawrence L.

Patent number: 7312370Abstract: An FCC process for obtaining light olefins comprises contacting a hydrocarbon feed stream with blended catalyst comprising regenerated catalyst and coked catalyst. The catalyst has a composition including a first component and a second component. The second component comprises a zeolite with no greater than medium pore size wherein the zeolite comprises at least 1 wt-% of the catalyst composition. The contacting occurs in a riser to crack hydrocarbons in the feed stream and obtain a cracked stream containing hydrocarbon products including light olefins and coked catalyst. The cracked stream is passed out of an end of the riser such that the hydrocarbon feed stream is in contact with the blended catalyst in the riser for less than or equal to 2 seconds on average. The hydrocarbon products including light olefins are separated from the coked catalyst. The first portion of the coked catalyst is passed to a regeneration zone in which coke is combusted from the catalyst to produce a regenerated catalyst.Type: GrantFiled: December 10, 2002Date of Patent: December 25, 2007Assignee: UOP LLCInventors: Rusty M. Pittman, Lawrence L. Upson

Patent number: 6616899Abstract: A high efficiency FCC process obtains the necessary regenerated catalyst temperature for a principally thermal cracking stage by cracking a light feedstock such as naphtha or a middle distillate in a first riser that principally performs thermal cracking and then cracks a heavy FCC feed in a second riser with a blend of catalyst from the principally thermal cracking step and recycle catalyst from the heavy feed to provide the necessary coke content on the catalyst that will produce high regenerated catalyst temperatures. The high temperature of the regenerated catalyst in the first riser provides a convenient means of cracking naphtha under high severity conditions and then using the remaining activity of the contacted catalyst for the principally catalytic reaction of the heavier feed. A separate thermal cracked product may be recovered from an intermediate blending vessel downstream of the first riser.Type: GrantFiled: November 19, 1999Date of Patent: September 9, 2003Assignee: UOP LLCInventor: Lawrence L. Upson

Patent number: 6238548Abstract: An FCC process converts a secondary feed comprising a heart cut of a gasoline product stream with spent catalyst at mild conditions to obtain a surprising increase in the octane number of the resulting gasoline product. More surprisingly, the increase in gasoline stream octane number occurs with very low production of dry gas. Limiting the presence of heavy gasoline components was found to significantly raise the octane number produced by the process.Type: GrantFiled: September 2, 1999Date of Patent: May 29, 2001Assignee: UOP LLCInventors: Lawrence L.

Patent number: 5371055Abstract: An FCC catalyst system and a process using the catalyst system are disclosed. The catalyst system comprises a metal trap component, such as bastnaesite or barium titanate, and a sulfur oxide acceptor such as a magnesium spinel in addition to a zeolite. The metal trap and sulfur oxide components are preferably in separate particles. The catalyst formulation results in improved activity believed to result from the sulfur oxide acceptor protecting the metal trap component from the harmful effects of sulfur oxides such as the formation of stable metal oxides.Type: GrantFiled: February 18, 1994Date of Patent: December 6, 1994Assignee: W.

Patent number: 4515903Abstract: A cracking catalyst having good resistance to metal poisoning has at least two particle fractions of different particle sizes, the cracking catalyzing zeolite material being concentrated to the coarser particle size fractions, and the finer particle size fractions being formed from material having relatively lower or no or insignificant cracking catalyzing activity. The particles of the finer particle size fractions have a matrix of kaolin and amorphous alumina-silica and may contain for example, an SO.sub.x eliminating additive such as Al.sub.2 O.sub.3, CaO and/or MgO. The coarser particle size fractions having cracking catalyzing effect have a mean particle size of from 80 to 125 .mu.m and the finer particle size fractions a mean particle size of from 30 to 75 .mu.m.Type: GrantFiled: February 17, 1984Date of Patent: May 7, 1985Assignee: Katalistiks B.V.Inventors: Jan-Erik A.
