METHOD FOR CONVERTING FEEDSTOCK FROM RENEWABLE SOURCE TO HIGH-QUALITY DIESEL FUEL BASE USING ZEOLITE CATALYST WITHOUT INTERMEDIATE GAS-LIQUID SEPARATION

摘要

PROBLEM TO BE SOLVED: To provide a method of treating feedstocks from renewable sources without intermediate gas-liquid separation to produce diesel fuel bases of excellent quality.;SOLUTION: The feedstocks used are raw vegetable oils or oils previously subjected to a prerefining stage, animal fats, or mixtures of such feedstocks. The method, allowing high diesel fuel base yields to be obtained from such feedstocks, includes a step (a) for performing hydrogenation, a step (b) for separating a hydrocarbon-containing base, a step (c) for removing a nitrogen compound, a step (d) for performing hydroisomerization, and a step (e) for separating the diesel fuel base.;COPYRIGHT: (C)2010,JPO&INPIT
