The feasibility of incorporating synthetic oil produced by the Fischer-Tropsch process from synthesis gas of a wood-biomass gasification process into the production of class K5 alternative low-pour-point fuels by processing in a blend with straight-run diesel distillate employing a two-stage scheme (first stage, hydrofining in the presence of conventional hydrofining catalyst Co-Mo/Al2O3; second, hydroisodewaxing) is investigated. It is shown that a nickel-molybdenum-containing hydroisodewaxing catalyst based on a binary mixture of zeolites (high-silica low-alkali zeolite TsVN of pentasil structure and mordenite) enables the production of diesel fuel for Arctic conditions (limit filterability temperature -45A degrees C) and aviation kerosene with an initial crystallization temperature of -63A degrees C. A mixture of boron and lanthanum oxides was used as the promoter; a mixture of amorphous aluminum silicate and gamma-alumina, as the binder.
