Abstract
The invention relates to a catalyst comprising: PA1 a matrix consisting of 0 and 100% by weight of .lambda. transition alumina, the complement up to 100% by weight of the matrix being in .gamma. transition alumina, and relative to the total weight of the catalyst, PA1 from 0.001 to 2% by weight of silicon, PA1 from 0.1 to 15% by weight of at least one halogen chosen from the group formed by fluorine, chlorine, bromine and iodine, PA1 from 0.01 to 2% by weight of at least one noble metal from the platinum group, from 0.005 to 10% by weight of at least one promoter metal chosen from the group formed by tin, germanium, indium, gallium, thallium, antimony, lead, rhenium, manganese, chromium, molybdenum and tungsten, and PA1 if required from 0.001 to 10% by weight of a doping metal.
