摘要： In a process for preparing a selectivated catalyst composition useful in the disproportionation of toluene, a catalyst comprising an acidic molecular sieve is contacted with a boron compound at a temperature in excess of 500° C.; and the resultant catalyst is then contacted with a medium containing hydrogen ions to at least partially restore the acid activity of the molecular sieve.

摘要： The invention relates to the use of particulate silicone resins in the absence of added organic solvents with particulate inorganic materials to form structured bodies and in particular molecular sieve containing structured bodies. The silicone resin is used in the form of a particulate with an average particle size of less than 700 um. Upon calcining, the silicone resin is converted to silica which acts as a binder.

摘要： A method is disclosed for modifying a catalytic molecular sieve for shape-selective hydrocarbon conversions comprises: a) selectivating said catalytic molecular sieve by contacting with a silicon-containing selectivating agent; and b) calcining the selectivated catalytic molecular sieve at high temperature calcination conditions comprising temperatures greater than 700° C., which conditions are sufficient to reduce acid activity as measured by alpha value and increase diffusion barrier of said catalytic molecular sieve as measured by the rate of 2,3-dimethylbutane uptake, as compared to the selectivated catalyst. Catalytic molecular sieves thus prepared, such as silica-bound ZSM-5, and their use in hydrocarbon conversion processes such as aromatics isomerization, e.g., xylene isomerization, ethylbenzene conversion and aromatics disproportionation, e.g., toluene disproportionation are also disclosed.

摘要： The sulfur content of liquid cracking products, especially the cracked gasoline, of the catalytic cracking process is reduced by the use of a sulfur reduction additive comprising a porous molecular sieve which contains a metal in an oxidation state above zero within the interior of the pore structure of the sieve. The molecular sieve is normally a large pore size zeolite such as USY or zeolite beta or an intermediate pore size zeolite such as ZSM-5. The metal is normally a metal of Period 3 of the Periodic Table, preferably zinc or vanadium. The sulfur reduction catalyst may be used in the form of a separate particle additive or as a component of an integrated cracking/sulfur reduction catalyst.

摘要： The sulfur content of liquid cracking products, especially the cracked gasoline, of the catalytic cracking process is reduced by the use of a sulfur reduction catalyst composition comprising a porous molecular sieve which contains a metal in an oxidation state above zero within the interior of the pore structure of the sieve as well as a cerium component which enhances the stability and sulfur reduction activity of the catalyst. The molecular sieve is normally a faujasite such as USY. The primary sulfur reduction component is normally a metal of Period 3 of the Periodic Table, preferably vanadium. The sulfur reduction catalyst may be used in the form of a separate particle additive or as a component of an integrated cracking/sulfur reduction catalyst.

摘要： There is provided a high efficiency base synthesis process for shape selective production of pyridine and picoline products from ammonia and C.sub.1-5 carbonyl compounds. The process includes reacting ammonia and at least one C.sub.1-5 carbonyl reactant under suitable reaction conditions of temperature, pressure, and space velocity in the presence of a catalyst comprising a molecular sieve to produce a primary product comprising pyridine or picoline products and polyalkylpyridines or other higher molecular weight aromatic species, separating and collecting the pyridine or picoline products from the polyalkylpyridines or other higher molecular weight aromatic species, and circulating the polyalkylpyridines or other higher molecular weight aromatic species to the same or another catalyst under conversion conditions to yield additional pyridine or picoline products with substantially reduced amounts of polyalkylpyridines or other higher molecular weight aromatic species.
