摘要： A heavy aromatics feed is converted to lighter aromatics products, such as benzene, by contacting a C9+ aromatics fraction and toluene over a first catalyst comprising a zeolite having a constraint index ranging from 0.5 to 3 and a hydrogenation component, and a second catalyst composition comprising an intermediate pore size zeolite having a constraint index ranging from 3 to 12 and a silica to alumina ratio of at least 5, whereby the amount of coboilers is reduced or eliminated.

摘要： Long chain alkyl substituted naphthalenes are produced by the alkylation of naphthalene with an olefin or other alkylating agent possessing at least 6 carbon atoms, usually 12 to 20 carbon atoms, in the presence of an alkylation catalyst comprising a zeolite having rare earths associated with less than 50 % of the exchangeable sites of the zeolite. The zeolite is usually a large pore size zeolite such as zeolite USY. The partial exchange with rare earths increases the selectivity of the catalyst for the production of long chain mono-alkyl substituted naphthalenes in preference to more highly substituted products.

摘要： A novel catalyst composition and process for catalytic cracking of a hydrocarbon oil. The catalyst comprises zeolite beta and a shape selective cracking component, preferably ZSM-5, and may include conventional cracking catalyst components such as zeolite Y. These components may be present in one particle or as a blend of separate particle additives. The composition increases light olefin yields and gasoline octane as compared to catalyst containing either, but not both of, ZSM-5 and zeolite beta.

摘要： Long chain alkyl substituted naphthalenes are produced by alkylating naphthalene with an olefin or other alkylating agent with at least 6, and usually 12 to 20 carbon atoms, in the presence of an alkylation catalyst comprising a zeolite having both ammonium and protonic species associated with the exchangeable sites of the zeolite. The zeolite is usually a large pore size zeolite such as USY. The presence of both ammonium and protonic species increases selectivity for production of long chain mono-alkyl substituted naphthalenes in preference to more highly substituted products.

摘要： Heavy oils are subjected to catalytic cracking in the absence of added hydrogen using a catalyst containing a zeolite having the structure of ZSM-12 and a large-pore crystalline zeolite having a Constraint Index less than about 1. The process is able to effect a bulk conversion of the oil while at the same time yielding a higher octane gasoline and increased light olefin content.

摘要： Bromine reactive hydrocarbon contaminants are removed from aromatic streams by first providing an aromatic feedstream having a negligible diene level. The feedstream is contacted with an acid active catalyst composition under conditions sufficient to remove mono-olefins. An aromatic stream may be pretreated to remove dienes by contacting the stream with clay, hydrogenation or hydrotreating catalyst under conditions sufficient to substantially remove dienes but not mono-olefins.
