Brief description of the hydrogenation of oils hydrocarbon-based heavy and apparatus works

摘要

P process of catalytic hydrogenation of a heavy hydrocarbon oil under pressure and at a high temperature, according to the process, the oil is sent into the reactors r1 to r5 connected in series and filled with a fixed bed of catalyst, the deactivated catalyst being continuously or periodically replaced by new catalyst, the deactivated catalyst being discharged from the reactors and the fresh catalyst being introduced into the reactors in the form of a suspension in oil by means of a network of supply pipes and of a network of discharge pipes which each reactor can be selectively connected and which are at the same pressure as the reactors. / p & & p & application to the treatments of hydrogenation of the heavy hydrocarbons. / p
