Process for the production of fuel and fuel additives capable for use for internal combustion engines and the fuels and fuel additives obtained

摘要

The invention provides a process for the production of paraffin fractions by special hydrocracking comprising the treatment of a feedstock with hydrogen at 160-420°C temperature and 5-100 bars pressure in the presence of a heterogeneous catalyst applied on a carrier, wherein the volumetric ratio of hydrogen to feedstock is 200-2000 Nm 3 /m 3 and the hourly feedstock load is up to 10 m 3 feed/m 3 catalyst, and wherein
- the feedstock comprises fatty acids and fatty acid esters;
- the process is carried out in the presence of a sulfidizing agent to maintain the sulfidized state of the sulfide catalyst at a constant level; and
- the process is carried out in the presence of an agent inhibiting oxidation and/or gum formation as indifferent material for controlling the reaction. The invention further provides four paraffin fractions obtained by the process.
