摘要： A moderate pressure hydrocracking process in which a highly aromatic, substantially dealkylated feedstock having a boiling point in the range between 300.degree. and 650.degree. F. is processed directly to high octane gasoline by hydrocracking over a catalyst, preferably comprising a large pore size, crystalline alumino-silicate zeolite hydrocracking catalyst such as zeolite Y together with a hydrogenation-dehydrogenation component. The feedstock which is preferably a light cut light cycle oil has an aromatic content of at least 50, usually at least 60 percent and an API gravity not more than 25. The hydrocracking typically operates at 600-1000 psig at moderate to high conversion levels to maximize the production of monocyclic aromatics which provide the requisite octane value to the product gasoline.

摘要： There is provided a continuous toluene disproportionation process to selectively produce para-xylene. The process includes a steady-state of operation, wherein the conversion of toluene and selectivity to para-xylene is maintained at essentially constant target levels. Prior to such a steady-state of operation, the reaction is conducted under a relatively high temperature.

摘要： This invention is concerned with removing metal and sulfur contaminants from residual oil fractions by catalytic contact with two different catalysts in the presence of hydrogen. In this process, the oil is first contacted with the major fraction of a catalyst comprising a Group VIB metal and an iron group metal oxide, such as a mixture of cobalt and molybdenum oxides, composited with an alumina support, the catalyst having at least 60% of its pore volume in pores of 100A to 200A diameter and at least about 5% of its pore volume in pores having a diameter greater than 500A. The oil is then contacted with a secondcatalyst of the high surface-area, cobalt-molybdenum on alumina type having a major fraction of its pores in the 30 to 100A diameter range. Finally, the oil is contacted with the remainder of the large-pore catalyst.

摘要： A moderate pressure hydrocracking process is disclosed in which substantially dealkylated heavy distillate feedstocks are processed directly to high octane gasoline over a catalyst, preferably comprising a crystalline silicate zeolite hydrocracking component having a Constraint Index less than 2. The bottoms fraction produced from the contacting may be passed to an FCC unit for further processing. In another embodiment, the substantially dealkylated heavy distillate feedstock may be fractionated into a lighter boiling stream and a heavier boiling stream for better ease of processing.
