Abstract
A process for converting feedstock triglycerides to lube basestocks. The process has the steps of (a) metathesizing the feedstock triglycerides with ethylene in the presence of a metathesis catalyst to form alpha olefins and medium-chain triglycerides and (b) hydroisomerizing the medium-chain triglycerides in the presence of a hydroisomerization catalyst and hydrogen to form methyl-branched triglycerides. The alpha olefins may be oligomerized in the presence of an oligomerization catalyst to form poly(alpha olefins).
Claims22
A process for converting feedstock long chain fatty acid glycerides to lube basestocks, comprising:
- (a) metathesizing the feedstock long-chain fatty acid glycerides with ethylene in the presence of a metathesis catalyst to form alpha olefins and medium-chain glycerides,
- (b) hydroisomerizing the medium-chain glycerides in the presence of a hydroisomerization catalyst and hydrogen to form methyl-branched glycerides, and
- (c) oligomerizing the alpha olefins in the presence of an oligomerization catalyst to form poly(alpha olefins).
