A method for synthesizing a zeolite bonded to a substrate utilizes a reaction mixture having a H. sub. 2 O/YO. sub. 2 molar ratio of at least 25 and Y is a tetravalent element, particularly silicon. A structure made according to this method includes a film of interconnected zeolite crystals bonded to a substrate and the structure is characterized by a value r representing the mg of zeolite/cm. sup. 2 of substrate surface and a value e representing the coating efficiency as mg of bonded zeolite/mg of YO. sub. 2 initially in the synthesis mixture; wherein r is at least 0. 5 and e is at least 0. 05. Processes are provided for separation, sorption, organic feedstock conversion and NO. sub. x conversion over the structure.

A process for shape selective hydrocarbon conversion involves contacting a hydrocarbon feedstream under conversion conditions with a catalytic molecular sieve which has been modified by treatment with an amino silane polymer while molecular sieve acid sites are protected. When the process is toluene disproportionation, a toluene feedstream may also contain a second silicon source which is a high p-xylene selectivating agent. The invention also includes the modification method and the shape selective catalyst which results from the modification.

A method is provided for increasing the catalytic activity of acid zeolite catalysts characterized by a silica to alumina mole ratio of at least 12 and a constraint index within the approximate range of 1 to 12, comprising contacting said zeolite catalysts with water for a sufficient treating time, temperature and water partial pressure to bring about said increased activity. The increase in catalytic activity is within a zone of enhanced activity, said zone is defined as encompassing all those conditions of treating time, temperature and water partial pressure and combinations thereof which yield catalytic activities greater than initial catalyst activity. The zeolite of enhanced activity of the method of the present invention can be utilized in improved acid catalyzed hydrocarbon conversion processes such as cracking, hydrocracking, alkylation, dealkylation, transalkylation, isomerization, dimerization, oligomerization, polymerization, addition, disproportionation, aromatization and hydration.

There is provided a process for producing a styrenic compound by reacting an aromatic compound with an aldehyde over an intermediate pore size molecular sieve catalyst. Such styrenic compounds include unsubstituted styrene and substituted styrene. Examples of such aromatic compounds include unsubstituted benzene and alkylbenzenes. An example of such an aldehyde is acetaldehyde. An example of such a catalyst is a ZSM-5 catalyst.

A process for shape selective hydrocarbon conversion involves contacting a hydrocarbon feedsteam under conversion conditions with a modified catalytic molecular sieve which has been modified by being pre-selectivated with a first silicon source, then steamed. The feedstream may also contain a second silicon source which is a high efficiency para-xylene selectivating agent. The method for modifying the molecular sieve is also described.
