摘要： The specification discloses a highly macroporous catalyst for hydroprocessing and hydroconversion of heavy hydrocarbon feedstocks. The high macroporosity catalyst incudes an inorganic oxide, molybdenum, and nickel components. It has a pore structure such that at least 18% of its total pore volume is in pores of a diameter greater than 5,000 angstroms and at least 25% of its total pore volume is in pores of a diameter greater than 1,000 angstroms. Preferably, the pore structure is bimodal. The catalyst is made by co-mulling the catalytic components with a high molecular weight polyacrylamide followed by forming the co-mulled mixture into a particle or an extrudate. The particle or extrudate is dried and calcined under controlled calcination temperature conditions to yield a calcined particle or extrudate of the high macroporosity catalyst composition.

摘要： Process for the preparation of a catalyst by adding, clay, boehmite, a first silica to form a slurry, digesting the slurry with a monoprotic acid to a pH of less than 4, adding one or more zeolites, adding a rare earth component to the slurry and mixing, adjusting the slurry pH to below 4 with monoprotic acid, adding a second silica anywhere in the preceding steps, destabilizing the slurry by raising the pH, shaping and collecting the resulting catalyst, wherein the resulting catalyst has enhanced mesoporosity.

摘要： A process for converting a hydrocarbon feed includes contacting a hydrocarbon feed with steam in the presence of a cracking catalyst under steam enhanced catalytic cracking conditions. The contacting the hydrocarbon feed with the steam in the presence of the cracking catalyst causes at least a portion of the hydrocarbon feed to undergo steam catalytic cracking reactions to produce a cracked effluent comprising C2 to C4 olefins, C6 to C10 aromatic compounds, or both. The cracking catalyst is a nanoparticle. The nanoparticle has a core and a shell. The core includes at least one zeolite particle, where the at least one zeolite particle includes ZSM-5 zeolites, Beta zeolites, Y-zeolites, or combinations of these zeolites. The shell is mesoporous and incudes silica (SiO2), alumina (Al2O3), or silica and alumina.

摘要： A method of making a xylene isomerization catalyst comprises the steps of (i) contacting a ZSM-5 zeolite starting material having a silica to alumina molar ratio of 20 to 50 and having a mesopore surface area in the range of 50 m2/gram to 200 m2/gram in a reactor with a base to provide an intermediate zeolite material; (ii) recovering the intermediate ZSM-5 zeolite material of step (i); (iii) contacting the intermediate zeolite material with an acid to provide an acid treated ZSM-5 zeolite product; (iv) recovering the acid treated ZSM-5 zeolite material; and (v) calcining the acid treated ZSM-5 zeolite material to provide a desilicated ZSM-5 zeolite product having a silica to alumina molar ratio of 20 to 150 and having a mesopore surface area in the range of 100 m2/gram to 400 m2/gram.
