摘要
Process for the hydroisomerization of long-chain n-paraffins which comprises isomerizing n-paraffins having a number of carbon atoms higher than 15 in the presence of hydrogen and a hydroisomerization catalyst which comprises: a) a carrier of acid nature consisting of a silica and alumina gel amorphous to X-rays, with a molar ratio SiO2/Al2O3 ranging from 30/1 to 500/1, and having a surface area ranging from 500 to 1,000 m2/g, a porosity ranging from 0.3 to 0.6 ml/g and a pore diameter within the range of 10-40 Angstrom; b) a mixture of metals belonging to groups VIB and VIII deposited on the carrier in an overall quantity ranging from 2 to 50% by weight of the total (a) + (b).
