    摘要： Petroleum refinery waste stream sludges are recycled by segregating the sludges according to their oil content. Sludges of high oil content are developed and then injected into a delayed coking unit during the coking phase so that they are converted to coke and liquid coking products. High water content sludges are used to quench the coke during the quench phase of the coking cycle, with minimal increases in coke volatile matter. The process increases the capacity of the delayed coking unit to process and recycle refinery waste sludges and produce a coke of lower volatile content.

    摘要： Catalytic cracking of hydrocarbon feedstocks is improved by hydrotreating the cracking feed under conditions of relatively low temperature, typically below 390.degree. C. for start-of-cycle, and high pressure, typically above 10,000 kPa, preferably above 12,000 kPa. The use of these conditions favors aromatics saturation to produce a cracking feed of improved crackability so that higher conversion is achieved in the cracking step at constant cracking conditions with production of naphtha of good octane quality. At the same time, desulfurization is achieved to maintain cracker SO.sub.x emissions at required levels; the advantages of high pressure operation are more notable at high denitrogenation severities while still achieving a low catalyst aging rate.

    摘要： A hydrocracking process for converting a petroleum feedstock to higher gravity, lower sulfur products, especially ultra low sulfur road diesel fuel. The process may be operated as a single-stage or two-stage hydrocracking. In each case, a hydrocracking step is followed directly by a post-treat hydrodesulfurization zone using a bulk multimetallic catalyst comprised of at least one Group VIII non-noble metal and at least two Group VIB metals with a ratio of Group VIB metal to Group VIII non-noble metal is from about 10:1 to about 1:10. In the two-stage option with interstage ammonia removal, the initial hydrocracking step may be followed by hydrodesulfurization using the bulk multimetallic catalyst prior to the ammonia removal which is followed by the second hydrocracking step. A final hydrodesulfurization over the bulk multimetallic catalyst may follow. The hydrodesulfurization over the bulk multimetallic catalyst is carried out at a pressure of at least 25 barg and preferably at least 40 barg.
