Use of a Dual-Bed System for Producing Diesel Fuel from a Mixture of Straight-Run Diesel and Rapeseed Oil over Sulfide Catalysts
A dual-bed catalytic system including MoS 2 /Al 2 O 3 and Co–MoS 2 /Al 2 O 3 catalysts is proposed for the process of production of diesel fuel with the sulfur content of less than 10 ppm from a straight-run diesel fraction containing 10–45 wt % rapeseed oil. The conversion of rapeseed oil to alkane...
