PROCESS AND SYSTEM FOR REDUCING THE OLEFIN CONTENT OF A FISCHER-TROPSCH PRODUCT STREAM
摘要
<p>A method is provided for converting synthesis gas to liquid hydrocarbon mixtures useful as distillate fuel and/or lube base oil. The synthesis gas is contacted with a synthesis gas conversion catalyst comprising a Fischer-Tropsch synthesis component in an upstream catalyst bed thereby producing an intermediate hydrocarbon mixture containing olefins and C21+ normal paraffins. The intermediate hydrocarbon mixture is subsequently contacted with a hydroisomerization catalyst and an olefin saturation catalyst, thereby resulting in a product containing no greater than about 25 wt% olefins and containing no greater than about 5 wt% C21+ normal paraffins. The hydroisomerization and olefin saturation catalysts may be in separate beds or mixed in a single bed downstream of the synthesis gas conversion catalyst.</p>
