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.
