Abstract
A method for upgrading a synthesis oil synthesized by the Fisher-Tropsch synthesis reaction, the method includes: a hydroisomerization step of hydroisomerizing the synthesis oil to remove alcohols and olefins, and converting at least a portion of normal paraffins with a carbon number of 5 or more into isoparaffins to obtain a hydroisomerized synthesis oil; a crude oil mixing step of mixing the hydroisomerized synthesis oil with a crude oil to obtain a mixed crude oil; a mixed crude oil transferring step of transferring the mixed crude oil to a crude oil distillation unit of a refinery; and a mixed crude oil refining step of processing the transferred mixed crude oil in petroleum refining facilities of the refinery including at least the crude oil distillation unit.
