Fremgangsmåde til hydrokonvertering i boblende leje af ladninger af biologisk fornybar oprindelse til fremstilling af brændstofbaser

摘要

Hydrotreatment and/or hydroconversion of a biorenewable mixture containing triglycerides and/or fatty acid structures (where the fatty chains comprising 8-25 carbons), comprises: (a) hydrotreating and/or hydroconversion of biorenewable mixture in a bubbling bed reactor in the presence of a granular catalyst comprising an amorphous support metal or metal compound having a hydro-dehydrogenating function, to produce first effluent; and (b) passing the effluent in a distillation area from which recovering a gaseous fraction and a distillate cut at boiling temperature of less than 400[deg] C.
