The invention relates to a process for preparing methyl mercaptan from a mixture of carbon oxide, hydrogen sulfide and hydrogen, in the presence of a catalyst based on molybdenum and potassium supported on zirconia, said catalyst not comprising any promoter.

Process for the preparation of methyl mercaptan

The invention relates to a catalyst comprising an active component based on molybdenum and on potassium and a support based on hydroxyapatite, and also to a process for preparing said catalyst and a process for producing methyl mercaptan in a catalytic process by reaction of carbon monoxide, sulphur and/or hydrogen sulphide and hydrogen, comprising the use of said catalyst.

Catalyst for the synthesis of methyl mercaptan and process for producing methyl mercaptan from synthesis gas and hydrogen sulphide

A process for preparing a mesoporous alumina is described, comprising the following steps:

Process for preparing an alumina with controlled mesoporosity

A catalyst contains at least one group VIII element and at least molybdenum and/or tungsten, said elements being present at least in part in the catalyst in the dry state in the form of at least one heteropolyanion with formula MABOHC, tHO; MABOHC, tHO; MABOHC, tHO; MABOHC, tHO; or MABOHC, tHO, in which M is cobalt and/or nickel and/or iron and/or copper and/or zinc, A is one or two elements from group VIII of the periodic table, B is molybdenum and/or tungsten and C is an Hion and/or a (NRRRR)type ammonium ion, in which R, R, Rand R, which may be identical or different, correspond either to a hydrogen atom or to an alkyl group and/or caesium and/or potassium and/or sodium, t is a number between 0 and 15 and x takes a value in the range 0 to 4 depending on the formula.
