Production process of high-class Diesel fuel

摘要

(57) Abstract The process which is something where it possesses the low temperature quality which is improved, as the Diesel fuel whose content of the aromatic compound is low it is the process which produces from the hydrocarbon feed the appropriate intermediate fraction as a starting material, as for this process, the origin of existence of hydrogen, the temperature which is heated and making the aforementioned feed material contact with the catalyst and one reaction process which have two functions under the pressure which is boosted, being something which it does simultaneously with the removal of the aromatic compound and the isomerization of paraffin, as for the aforementioned catalyst, includes the hydrogenation metal component in addition to with molecular sieve and the carrier and is. The aforementioned molecular sieve desirably is crystal aruminoshiriketo or crystal shirikoaruminohuosuhueto, the aforementioned catalyst VI in the element periodic ratio charts or includes the metal which is chosen from the metal which belongs to VIII group as a hydrogenation/a dehydrogenation transformation amount.
