    摘要： An asphalt-containing mineral oil can be deasphalted at temperatures above about 80.degree. C. with methanol serving as the deasphalting solvent. Two liquid phases are produced, an asphalt-rich phase and a methanol-rich phase. By cooling the methanol-rich phase to a temperature below 80.degree. C., two additional liquid phases are produced, an oil-rich phase and a methanol-rich phase.

    摘要： A process for producing alkyl aromatic compounds which comprises contacting at least one aromatic compound with at least one alkylating agent or transalkylating agent possessing at least one aliphatic group having from 1 to 5 carbon atoms under alkylation or transalkylation reaction conditions and in the presence of an alkylation or transalkylation catalyst, to provide an alkylated aromatic product possessing at least one alkyl group derived from said alkylating agent or transalkylating agent, said catalyst comprising a binder-free molecular sieve having an X-ray diffraction pattern that includes the lines set forth in Table A.

    摘要： Low sulfur gasoline of relatively high octane number is produced from a catalytically or thermally cracked, olefin-rich, sulfur-containing hydrocarbon stream by hydrodesulfurization followed by treatment over an acidic catalyst containing a molecular sieve belonging to the MCM-22 family in combination with a metal component, preferably selected from the transition elements of the 4th and 5th periods of the Periodic Table. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the hydrocarbon feed.
