SULFUR RESISTANT HYDROCONVERSION CATALYST AND HYDROPROCESSING OF SULFUR-CONTAINING LUBE FEEDSTOCK

摘要

The present invention relates to a kind of novel platinum-nickel alloys catalyst for hydrofinishing and is hydrocracked the raw material of non-low sulfur content and technique hydrofinishing and the charging of non-low sulfur content as being hydrocracked are fed. The catalyst keeps the sulfur tolerance of active palladium catalyst and platinum catalyst, without usually with the higher reaction temperature of platinum base catalyst, to avoid the manufacture Lube basic oil material feedstocks of the undesirable cracking reaction of higher rate.
