The invention provides four products, wherein
Product A is a paraffin fraction comprising 98.0-99.9% by weight C4-C12 i- and n-paraffins with 1:4 to 4:1 i/n ratio and 0.1-2.0% by weight C4-C10 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 C10-C25 i- and n-paraffins with 1:9 to 3:2 i/n ratio and 0.05-1.00% by weight C12-C14 carboxylic acids and/or C12-C16 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 C9-C14 carboxylic acids and 80-95% by weight C12-C19 carboxylic acid esters.
Product D is a paraffin fraction comprising C10-C26 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 Nm3/m3 and the hourly feedstock load is up to 10 m3 feedstock/m3 catalyst.
