The article discusses the features of obtaining liquid synthetic motor fuels from natural gas and other carbonaceous raw materials. The use of such fuels in the operation of construction and road equipment can help reduce the negative impact on the environment, especially in areas with increased requirements for air quality. It has been shown that one of the effective methods for obtaining synthetic fuel fractions is one-pot synthesis using bifunctional catalysts, which make it possible to combine the hydrocarbon synthesis process and the hydroprocessing stage, including hydrocracking and hydroisomerization processes.
