摘要： This invention relates to a silicon enhanced amorphous silica-alumina (SEASAL) composition. The composition is characterized in that from about 3 to about 22 mole percent of the aluminum atoms in a host amorphous silica-alumina have been replaced by silicon atoms. Additionally, the SEASAL contains from about 0.5 to about 10 weight percent fluoride and has a cracking activity of at least 30%. The SEASAL is prepared by reacting a host amorphous silica-alumina with a fluorosilicate salt, thereby removing aluminum atoms and inserting silicon atoms. The SEASAL compositions have uses in hydrocarbon conversion processes such as hydrocracking, cracking and alkylation.

摘要： This invention presents a novel catalyst formulation for the isomerization of alkylaromatic hydrocarbons. The catalyst is comprised of at least one Group VIII metal, and a pentasil zeolite having an x-ray diffraction characteristic of ZSM-12 wherein a portion of the aluminum atoms have been replaced with gallium atoms. When utilized in a process for isomerizing a non-equilibrium mixture of xylenes containing ethylbenzene, a greater yield of paraxylene is obtained compared to prior-art processes.

摘要： Hydrocarbons are reduced in molecular weight in a conversion process wherein they are contacted with a non-zeolitic solid catalyst comprising an alumina, such as gamma alumina, which has been isomorphously substituted with silicon. The treated alumina will have a fluorine to silicon mole ratio of about 0.8:1 to about 1.3:1. For use in hydrocracking, the catalyst contains a metal hydrogenation component and possibly one or more other inorganic oxides such as silica-alumina. Other non-zeolitic materials such as delaminated clay or silica-alumina may also be composited into the catalysts.

摘要： This invention relates to novel silicon enhanced aluminas (SEAL), processes to prepare them, and hydrocarbon conversion processes using the SEALs. The SEAL compositions have a bulk empirical formula of Al.sub.2-x Si.sub.x O.sub.3 F.sub.x where x varies from about 0.01 to about 0.5. This SEAL material has a three-dimensional pore structure with the pores having diameters in the range of about 20 to about 300.ANG., a crystal structure characteristic of alumina, and where the surface of the SEAL has a higher silicon concentration than the interior of the SEAL. The SEAL is prepared by contacting an alumina with a fluorosilicate salt. This SEAL can be calcined to give a calcined seal with a formula Al.sub.2-x Si.sub.x O.sub.3 F.sub.y where x is as defined above and y varies from 0.01 to x. The calcined SEAL contains both strong and weak acid sites. These SEAL compositions are particularly useful in hydrocracking, cracking and alkylation processes.
