ABSTRACT:
The invention relates to the catalytic treatment of a gas oil feed stock, distilling between 150.degree. and 530.degree. C., in a reactor zone whose temperature is comprised between 200.degree. and 500.degree. C., the pressure is comprised between 15 and 80 bars and containing a hydrogen form zeolite as catalyst, in the presence of a quantity of isobutane representing from 5 to 100% of said feed stock.
The process is particularly suitable for the improvement of the filtration temperature limit of the gas oils.
