Patent number: 10000712Abstract: A method for producing diesel fuel from biocomponent feeds includes hydrotreating the feed followed by catalytic dewaxing with a 1-D, 10 member ring molecular sieve containing catalyst. The hydrotreated feed may be cascaded directly to the dewaxing step, or the hydrotreated feed can undergo intermediate separation. The diesel fuel resulting from processing of the biocomponent feed exhibits superior cetane values.Type: GrantFiled: June 8, 2016Date of Patent: June 19, 2018Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: William J.

Patent number: 7713407Abstract: 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.Type: GrantFiled: June 2, 2006Date of Patent: May 11, 2010Assignee: ExxonMobil Research & Engineering CompanyInventors: William J.

Patent number: 5705724Abstract: A process is disclosed for the production of alkylaromatic compounds employing olefinic liquid from thermally or catalytically cracked plastics as alkylating agent. The process comprises contacting a feedstream comprising alkylatable aromatics and the olefinic liquid with acidic alkylation catalyst under alkylation conditions in an alkylation zone; and recovering an effluent stream comprising alkylaromatic compounds. The alkylation can be performed with the product of plastics pyrolysis or with non-degraded plastic feedstock in-situ with thermal/catalytic degradation of the plastic.Type: GrantFiled: October 26, 1995Date of Patent: January 6, 1998Assignee: Mobil Oil CorporationInventors: Nick A.

Patent number: 5009767Abstract: 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.Type: GrantFiled: September 21, 1989Date of Patent: April 23, 1991Assignee: Mobil Oil CorporationInventors: Mark P.

Patent number: 4786401Abstract: Hydrocarbon-containing liquid waste sludges from refinery waste streams can be disposed of by blending with the feedstock being passed to a fluid catalytic cracking unit. Preferably, the sludge is premixed with a hydrocarbon, such as a light oil, prior to mixing with the feed.Type: GrantFiled: September 25, 1987Date of Patent: November 22, 1988Assignee: Mobil Oil CorporationInventors: Solomon M.

Patent number: 4780193Abstract: 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.Type: GrantFiled: December 22, 1986Date of Patent: October 25, 1988Assignee: Mobil Oil CorporationInventors: W.
