摘要： High octane gasoline and high quality distillate are co-produced by a hydrocracking light cycle oil from a catalytic cracking process under conditions of low to moderate hydrogen pressure and severity to produce a high octane, hydrocracked gasoline. The distillate fraction from the hydrocracker is separated to form a first fraction which boils immediately above the gasoline fraction and a second, higher boiling fraction which is withdrawn as product. The first distillate fraction is recycled, preferably to extinction, to the cracker to increase the paraffinic content of the higher boiling distillate product by removal of the hydroaromatic components in the recycled fraction. The recycled fraction may be mixed with fresh feed to the cracker or may be injected at a higher level in the cracking riser as a secondary feed injection. The paraffinic distillate product has a low sulfur content and a high cetane index and is useful as a road diesel fuel.

摘要： High octane gasoline and high quality distillate are co-produced by a hydrocracking process in which a catalytic cracking light cycle oil is hydrocracked under conditions of low to moderate hydrogen pressure and severity to produce a high octane, hydrocracked gasoline. The distillate fraction which boils immediately above the gasoline fraction is recycled to the hydrocracker to increase the paraffinic content of this fraction by partial saturation and cracking of the aromatics contained in it so as to form a paraffinic distillate of low sulfur and high cetane index which is useful as a road diesel fuel. A higher boiling distillate fraction of relatively lower aromaticity may also be produced for use as a low sulfur fuel oil. The recycled fraction may be cooled to provide quench for the hydrocracker.

摘要： Each application executing on an application server uses an extended version of the Berkeley Packet Filter (BPF) language to define an application-specific rule set. The application server also includes a Just-In-Time compiler to compile the BPF rule set. The compiled rule set is downloaded to a Packet Forwarding Entity (PFE) in the network, and used to control how the PFE steers data packets generated by the application through a communications network.

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： The concentration of sulfur trioxides in an FCC unit regenerator is maintained within environmentally accepted limits, while maintaining an adequate amount of gas for fluidizing conditions in the regenerator, by admixing the regenerator oxygen-containing gas with an inert gas. The quantity of the inert gas is controlled by a control loop measuring the pressure drop in the regenerator, and adjusting the amount of the inert gas to maintain the pressure drop within the predetermined limits.
