PCT No. PCT/FR91/00992 Sec. 371 Date Aug. 10, 1992 Sec. 102(e) Date Aug. 10, 1992 PCT Filed Dec. 10, 1991 PCT Pub. No. WO92/10289 PCT Pub. Date Jun. 25, 1992.A catalyst is provided based on chlorinated eta alumina incorporating platinum and germanium and tin, as well as chlorine. This catalyst can be used in a process for the isomerization of a charge rich in normal C4-C6-paraffins, without hydrogen recycling.
