摘要： A process for the coproduction of purified benzene and ethylene is provided. The method comprises providing a first mixture comprising benzene, toluene, and one or more C6 to C7 non-aromatics and separating the majority of the benzene and the one or more C6 to C7 non-aromatics from the majority of the toluene to form a second mixture containing benzene and at least a portion of the one or more C6 to C7 non-aromatics. Thereafter at least about 80% of the C6 to C7 non-aromatics in the second mixture are cracked while maintaining essentially no cracking of benzene to produce a cracked product containing ethylene, propylene and pyrolysis gasoline comprising olefins, di-olefins and benzene. The pyrolysis gasoline is preferably hydrotreated and then fractionated to form a purified benzene product comprising at least about 80 wt % benzene. The purified benzene can be used as a feed to a liquid phase or mixed phase alkylation and/or to produce ethylbenzene or cumene.

摘要： The invention relates to a process for the preparation of acetylene and synthesis gas by thermal treatment of a starting mixture containing one or more hydrocarbons and in addition molecular oxygen and/or one or more compounds containing the element oxygen, in which the starting mixture is heated, brought to reaction in a reactor and subsequently cooled. The process has the special feature that the starting mixture is heated to a maximum of 1400° C. It is then possible to carry out the process with comparatively little expenditure of energy.

摘要： Olefins may be produced by thermally steam cracking residuum containing a short residuum having a boiling point range greater than 565° C. wherein at least 3 weight percent of the short residuum has a boiling point greater than or equal to 650° C. The residuum has pentane insolubles less than or equal to 1.2, ASTM 893. Further, the weight percent of hydrogen of the residuum is greater than or equal to 12.5. Such feedstocks are produced by hydrotreating, where necessary, a petroleum residuum having pentane insolubles less than 1.0, ASTM 893, until the weight percent of hydrogen of the petroleum residuum is 12.5. Where necessary, the petroleum residuum may be deasphalted prior to subjecting it to hydrotreatment.
