Process for converting a carbonaceous material to lower paraffinic hydrocarbons and monocyclic aromatic hydrocarbons

A carbonaceous material is subjected, in admixture with a hydrogenated recycle oil, to hydrogenation in two successive steps at respective temperature ranges of 350 DEG -470 DEG C. and 600 DEG -1000 DEG C., under a pressure of at least 20 bars, the resulting product being separated into a carbonaceo...

Beschreibung
Zusammenfassung:	A carbonaceous material is subjected, in admixture with a hydrogenated recycle oil, to hydrogenation in two successive steps at respective temperature ranges of 350 DEG -470 DEG C. and 600 DEG -1000 DEG C., under a pressure of at least 20 bars, the resulting product being separated into a carbonaceous solid residue, which is subsequently treated with oxygen and steam so as to obtain a hydrogen-containing reducing gas to be used in the second of the two hydrogenation steps, a fraction distilling in major part above 150 DEG C. which, after hydrogenation, forms the recycle oil admixed with the starting carbonaceous material, and a fraction containing the desired lower paraffinic hydrocarbons and monocyclic aromatic hydrocarbons, distilling in major part below 150 DEG C.
