Abstract: The impact of various parameters of the hydrotreatment of plant lipids, such as the hydrogen-to-fatty acids ratio, weight hourly space velocity (WHSV), and the temperature, on the components and fractional composition of a liquid organic product has been studied. Depending on the process parameters, the main products can be either motor fuel components (normal and isomerized alkanes), or oxygen-containing compounds of interest for the chemical industry (fatty alcohols). A formation of the predominantly “diesel” fraction with the iso-alkanes to normal alkanes ratio equal to 8.6 that resulted in the yield of iso-alkanes equal to 61 wt % was achieved at a hydrogen-to-fatty acid ratio of 2200 m3/m3, T = 300°C, P = 2.5 MPa, and WHSV = 2.1 h–1. The WHSV increase to 8.4 h–1 makes it possible to obtain an organic product consisting mainly of O-containing compounds (fatty alcohols, fatty acid esters, lactones) with the yield of 51 wt %.
