HYDROISOMERIZATION OF A PREDOMINANTLY N-PARAFFIN FEED TO PRODUCE HIGH PURITY SOLVENT COMPOSITIONS

摘要

A process for the hydroisomerization of a predominantly C8-C20 n-paraffin ic feed to produce a high purity C8-C20 paraffinic solvent composition having superior low temperature properties, and low viscosities. The feed is contacted, with hydrogen, over a dual functional catalyst to hydroisomerize and convert the feed to a product comprising a mixture of n-paraffins and isoparaffins, the isoparaffins component of which contains greater than 50 percent of mono-methyl species, with the mola r ratio of isoparaffins:n-paraffins ranging from about 0.5:1 to 9:1.
