Title:
METHOD FOR THE PRODUCTION OF MIDDLE DISTILLATES BY HYDROISOMERISATION ET HYDROCRACKING OF CHARGES ARRISING FROM THE FISCHER-TROPSCH METHOD
Document Type and Number:
WIPO Patent Application WO2004076598
Kind Code:
A8
Abstract:
The invention relates to a method for the production of middle distillates from a paraffin charge produced by Fischer-Tropsch synthesis, using a hydrocracking / hydroisomerisation catalyst comprising at least one hydrogenating/dehydrogenating element selected from the group consisting of noble elements of group VIII of the periodic table of elements, a non-zeolithic support based on silica-alumina containing more than 5 wt. % and less than or equal to 95 wt. % silica (Si02), a porous median diameter measured by mercury-pump porosimeter of 20 - 140 ANGSTROM , a total porous volume measured by mercury-pump porosimeter of 0.1 ml/g 0.6 ml/g, a total porous volume measured by nitrogen-pump porosimeter of 0.1 ml/g 0.6 ml/g, a specific BET surface of 100 - 550 m<2>/g, a porous volume measured by mercury-pump porosimeter in pores whose diameter is more than 140 ANGSTROM of less than 0.1 ml/g, a porous volume measured by mercury-pump porosimeter in pores whose diameter is more than 160 ANGSTROM of less than 0.1 ml/g, a porous volume measured by mercury-pump porosimeter in pores whose diameter is more than 200 ANGSTROM of less than 0.1 ml/g, a porous volume measured by mercury-pump porosimeter in pores whose diameter is more than 500 ANGSTROM of less than 0.01 ml/g and an X diffraction diagram containing at least the main lines characteristic of at least one of the transition aluminas included in the group made up of alpha, rho, chi, eta, gamma, kappa, theta et delta aluminas.
