Hydrofining of vegetable, synthetic, and petroleum blendstocks to produce diesel fuel

Аннотация

The process of co-hydrofining of pyrolysis products and Fischer–Tropsch synthetic crude with petroleum diesel distillate at a pressure of 5–8 MPa and 330–370°C in the presence of a conventional CoMo–Al₂O₃ hydrotreating catalyst has been studied, and the trends in the behavior of the physicochemical characteristics of the resulting products have been revealed. The feasibility of manufacturing class K5 diesel fuel containing the alternative components in amounts of 20 and 30 vol % by involving the pyrolysis products and synthetic crude, respectively, in the process has been demonstrated.
