REACTION SYSTEM FOR PRODUCTION OF DIESEL FUEL FROM VEGETABLE AND ANIMAL OILS

摘要

Abstract A process for producing a fuel composition from vegetable and/or animal oil comprises feeding the oil to a tubular reaction unit containing a catalyst comprising an acidic component and a metal component, feeding effluent from the tubular reaction unit to a vapor-liquid separator, and feeding a vapor phase separated from the effluent from the tubular reaction unit to an adiabatic reaction unit comprising the same catalyst as in the tubular reaction unit comprising an acidic component and a metal component. The produced fuel composition has acceptable lubricity and comprises a mixture of C₁₂ to C₁₈ or C₁₄ to C₁₈ paraffins having a ratio of iso to normal paraffins of 2 to 8 and less than 5 ppm sulfur.
