Patent Number Title Of Patent Date Issued
5071539 FCC catalysts of increased effective heat capacity December 10, 1991
A catalytic composition for use in fluid catalytic cracking has an effective heat capacity of at least about 0.29 BTU/lb. .degree.F. over the range from 950.degree. F. to 1300.degree. F. The composition may include microspheres containing in situ crystallized Y-faujasite and fluidizable
4965233 Novel zeolite fluid cracking catalysts and preparation thereof from mixtures of calcined clay October 23, 1990
A novel improved process for maunfacturing fluid cracking cataylsts by an in situ procedure. Sodium zeolite Y (synthetic faujasite) is crystallized in pores of a physical mixture of preformed, highly porous precursor microspheres, one portion of the microspheres is composed of metakaolin
4790929 Hydrotreating process using porous mullite December 13, 1988
A process for treating heavy hydrocarbon oil which contains metals and/or sulfur in the presence of a catalyst and recovering a hydrocarbon product having reduced metals and/or sulfur content by employing a metal impregnated mullite catalyst. The impreganted metals are selected from the
4699893 Fluid cracking catalyst and method of making same from waste catalyst manufacture fines October 13, 1987
An improved process for ion-exchanging sodium ions in particles containing sodium form zeolite crystals and sodium silicate. The process involves an initial ion-exchange at pH about 4.5 to 5.0 with an ammonium salt followed by exchange with an ammonium salt at about pH 2.0 to 3.5. Cracki
4628042 Porous mullite December 9, 1986
Clay convertible by thermal treatment into crystalline mullite and silica is formed into green coherent bodies of desired size and shape such as, for example, microspheres, pellets or honeycombs. The bodies are then calcined to convert the clay into a mixture of crystalline mullite and
4608357 Catalytic cracking with mullite composition promoted combustion of carbon monoxide August 26, 1986
The present invention provides novel catalyst products for promoting the combustion of carbon monoxide, particularly in catalytic cracking units, especially FCC units. The improved products of the invention comprise one or more catalytically active metals selected from the group consisti
4606813 Fluid catalytic cracking catalyst for cracking sulfur containing petroleum feedstocks and a proc August 19, 1986
The present invention is directed to a fluid catalytic cracking catalyst comprising a blend of a catalytically active first component and a second component for reducing the emissions of oxides of sulfur from the regenerator of a catalytic cracking unit and the use of that catalyst to
4601997 Porous mullite July 22, 1986
Clay, preferably kaolin, is calcined through its exotherm, but without substantial mullite formation (e.g., 1 hour at 1000.degree. C.). The calcined clay is leached with an alkaline aqueous solution to remove (i.e., leach) silica. The severity of leaching, i.e., amount of silica remo
4581340 Fluid cracking catalyst and method of making same from waste catalyst manufacture fines April 8, 1986
Co-product fines from the manufacture of zeolitic cracking catalysts from microspheres of calcined clay have heretofore been discarded as a waste stream. These fines, recovered as a moist cake, are slurried in a sodium silicate solution, spray dried to form microspheres and ion-exchanged
4520119 Cracking catalyst and manufacture thereof May 28, 1985
By-product fines from the manufacture of zeolitic cracking catalysts from microspheres of calcined clay have heretofore been discarded as a waste stream. These fines, recovered as a moist cake, are slurried in a sodium, silicate solution, spray dried to form microspheres and ion-exchange
4493902 Fluid catalytic cracking catalyst comprising microspheres containing more than about 40 percent January 15, 1985
This application discloses novel fluid catalytic cracking catalysts comprising microspheres containing more than about 40%, preferably 50-70%, by weight Y-faujasite zeolite, methods for making such catalysts, and the use of such catalysts to crack petroleum feedstocks, particularly those
