METHOD FOR CONVERSING RAW MATERIAL FROM REUSABLE SOURCE MATERIAL TO DIESEL FUEL BASE WITH GOOD QUALITY BY USING ZEOLITE TYPE CATALYST

摘要

PROBLEM TO BE SOLVED: To provide a method for getting a high quality diesel fuel base in a high yield from a not processed vegetable oil or an oil given as a reserve to a preliminary purification step, an animal oil or a charged raw material from such reusable sources.;SOLUTION: The method includes steps as shown below (a) a step for hydrogenation treating a charged raw material in the presence of a fixed-bed catalyst having hydrogenation and dehydrogenating function and containing an amorphous carrier, (b) a step for separating the hydrogen, gas and at least one kind of base containing hydrocarbon from an effluent from step (a), and (c) step for hydrogenating and isomerizing at least a part of the hydrocarbon containing base from the step (b) in the presence of a fixed-bed hydrogenating and isomerizing selective catalyst including at least one kind of VIII family metals and/or VIB family metals and one kind of one dimensional 10MR zeolite molecular sieve, (d) a step for separating hydrogen, a gas and at least one kind of diesel fuel base from an effluent from step (c).;COPYRIGHT: (C)2010,JPO&INPIT
