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 four products, wherein Product A is a paraffin fraction comprising 98.0-99.9% by weight C 4 -C 12 i- and n-paraffins with 1:4 to 4:1 i/n ratio and 0.1-2.0% by weight C 4 -C 10 carboxylic acid esters, wherein the boiling range of the paraffin fraction is 20-250°C. Product B is a paraffin fraction comprising 95.00-99.95% by weight C 10 -C 25 i- and n-paraffins with 1:9 to 3:2 i/n ratio and 0.05-1.00% by weight C 12 -C 14 carboxylic acids and/or C 12 -C 16 carboxylic acid esters, wherein the boiling range of the paraffin fraction is 160-400°C. Product C is a polar product mix comprising 5-20% by weight C 9 -C 14 carboxylic acids and 80-95% by weight C 12 -C 19 carboxylic acid esters. Product D is a paraffin fraction comprising C 10 -C 26 i- and n-paraffins with 1.5:1 to 5:1 i/n ratio, wherein the boiling range of the paraffin fraction is 160-420°C. The invention further provides a process for the production of paraffin fractions by a special hydrocracking, wherein the feedstock is treated with hydrogen in the presence of heterogeneous catalyst applied on a carrier at 160-420°C temperature and 5-100 bars pressure, where the volumetric hydrogen to feedstock ratio is 200-2000 Nm 3 /m 3 and the hourly feedstock load is up to 10 m 3 feedstock/m 3 catalyst.
