Zusammenfassung:	PCT No. PCT/FR95/00352 Sec. 371 Date Apr. 3, 1996 Sec. 102(e) Date Apr. 3, 1996 PCT Filed Mar. 22, 1995 PCT Pub. No. WO95/26819 PCT Pub. Date Oct. 12, 1995The invention concerns a catalyst for conversion of hydrocarbon feeds. The catalyst is essentially constituted by 0.05% to 10% by weight of a precious metal and a silica (5-70%)/alumina support with a specific surface area of 100-500m2/g. The catalyst has an average pore diameter of 1-12 nm, the pore volume of pores with diameters between the average diameter+/-3 nm being more than 40% of the total pore volume. The dispersion of the precious metal is 20-100% and the distribution coefficient for the precious metal is greater than 0.1. The invention also concerns a process for the hydroisomerization of feeds with boiling points of more than 350 DEG C. using this catalyst. The process is operated between 200 DEG C. and 450 DEG C. at 2-25 MPa with a VVH of 0.1-10 h-1 and a hydrogen/feed volume ratio of 100-2000.
