Abstract: The invention relates to chemical industry and is directed to the production of middle distillate from vegetable oils. In the first step of the production method, the fatty acids or triglycerides of said vegetable oils are hydrogenated to give n-paraffins, and in the second step, the n-paraffins are catalytically converted to paraffins with branched chains. Using this process having two steps, a high-quality middle distillate useful as a component of diesel fuels without any particular specifications may be produced.
