Production manner of the high-class lubricating basic oil supply raw materials from the not yet conversion oil of the fuel oil hydro-cracking process which is operated by recycling format

摘要

(57) Abstract As for manner in order to produce the high-class lubricating basic oil supply raw materials by this invention, very high viscosity characteristic being something regarding the manner which produces the high-class lubricating basic oil supply raw materials which possess low volatility making use of the not yet conversion oil (UCO) which excessive is done with fuel oil hydro-cracking reaction process, everything which excessive is done or supplying the not yet conversion oil of part to the 2nd decompression distillation process continually from fuel oil hydro-cracking reaction process, it produces the lubricating basic oil supply raw materials of various classes which possess the desire viscosity range not only, as for this kind of decompression distillation process in the recycling oil streamBeing accumulated, the desirable heat resistance where product choice performance and the catalytic converter performance in the hydro-cracking reaction process with recycling format and it can decrease quickly heavily it can remove the hydrocarbon and the polynuclear aromatic compound effectively.
