Antifoam to achieve high conversion in hydroconversion of heavy oils
摘要
A process for the conversion of a heavy hydrocarbon oil in the presence of hydrogen and a catalyst or additive is described. It is shown that conversion can be increased by injecting an anti-foaming agent or a solution of anti-foaming agent in light oil into the reactor. Significantly better results are obtained when the anti-foam or the solution of anti-foam is injected directly into the top section of the reactor.
