Production of fuel-grade hydrocarbons from renewable raw materials

One of the actively developing areas in the current production of motor fuel components from renewable raw materials consists in the processing of vegetable oils using various catalytic processes. The object of research in this paper was rapeseed oil and the products of its processing on a hydrotreating catalyst. The choice of rapeseed oil as a raw material for processing is due to the large acreage it occupies on the territory of the Russian Federation as food industry, currently being produced mainly for export. The authors investigated a process of catalytic processing of rapeseed oil using a hydrotreating catalyst. The processing was carried out in a laboratory catalytic unit at a temperature of 375 °C, a pressure of 7 MPa, and a volume feed rate of 1 h^-[1]; the hydrogen consumption was 2×10^-4 m³/h Physicochemical and low-temperature properties were determined for the feedstock and catalytic processing product. In addition, the component composition was determined for the resulting catalytic reprocessing product. The main directions of chemical transformations of rapeseed oil components into hydrocarbons on a hydrotreating catalyst are considered. The possibility of using rapeseed oil as a feedstock for producing fuel hydrocarbons – in particular n-alkanes, iso-alkanes and alkenes, which are promising raw materials for the production of motor fuel components – is substantiated.
