When producing hydrocarbons from fatty acid esters contained in fats or fat oils, the fatty acid esters initially are split up by hydrolytic decomposition into a first stream containing crude alcohol and water and a second stream containing free fatty acids, and subsequently the free fatty acids of the second stream are hydrogenated with hydrogen to obtain saturated hydrocarbons.

Process and plant for producing hydrocarbons

The invention relates to a method for a high temperature short-time distillation of residual oil. The method according to the invention is characterized by a technically simple recovery of a small residual fraction from a gas and/or oil vapour mixture produced by a mixing apparatus (). Said small residual fraction contains large quantities of undesirable polluting catalytic substances (CCR, Ni, V, asphaltenes). For this purpose, the gas and/or oil vapour mixture produced by the mixing apparatus () is diluted with gas or water vapour in a column () at a temperature of 450&#xb0; C. in such a way that a high boiling fraction, which has a high content of the pollutant substances and whose initial boiling point is higher than 450&#xb0; C., is condensed and extracted. Another realization of the method consists in introducing a non condensed oil produced in the column () into a fractionating column (), where said oil is decomposed in order to produce a depressurized gas oil fraction having a low content of pollutants and a benzine/gas oil fraction.
