Abstract: At least one olefin and at least one isoparaffin are converted to a diesel fuel blending component by contacting the olefin and the isoparaffin with a catalyst selected from MCM-22, MCM-36, MCM-49, and MCM-56 to provide a product containing a diesel fuel.

Abstract: Ethylbenzene is produced by the alkylation of benzene with ethylene in the presence of an alkylation catalyst having a particular structure defined by its X-ray diffraction pattern. A preferred catalyst is the zeolite MCM-22. The process is typically carried out at a temperature of 300.degree. to 1000.degree. F. but the catalyst provides sufficient activity for the reaction to be carried out at temperatures below 700.degree. F. Liquid phase operation is preferred, giving a lower yield of polyethylated products. The use of the selected catalyst also results in a reduction of the xylene impurity level to values below 500 ppm in the product.

Abstract: A hydrocracking catalyst with improved distillate selectivity comprises, in addition to a metal component, a mesoporous crystalline material together with a molecular sieve component of relatively smaller pore size. The metal component of the catalyst is preferably associated with the high-surface area mesoporous component and high-metal loadings can be achieved in order to give good hydrogenation activity to the catalyst. The relatively smaller pore size component is preferably a large pore size zeolite such as zeolite Y or an intermediate pore size zeolite such as ZSM-5; this component provides a higher level of acidic functionality than the mesoporous component, achieving a functional separation in the hydrocracking process, permitting the metals loading and acidic activities to be optimized for good catalyst selectivity and activity. The catalysts enable the distillate selectivities comparable to amorphous catalyst to be achieved with improved conversion activity.

Abstract: A moderate pressure hydrocracking process in which a highly aromatic, substantially dealkylated feedstock is processed to high octane gasoline and low sulfur distillate by hydrocracking over a catalyst, preferably comprising ultrastable Y and a Group VIII metal and a Group VI metal, in which the amount of the Group VIII metal content is incorporated at specified proportion into the framework aluminum content of the ultrastable Y component. The feedstock which is preferably a 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 400-1000 psig at moderate to high conversion levels to maximize the production of monocyclic aromatics which provide the requisite octane value to the product gasoline. The distillate products from the hydrocracker are reduced in their sulfur content.
