Process for elimination of mercury in hydrocarbon charges wherein said charge is contacted, under hydrogen, with a catalyst containing at least one metal from the group consisting of nickel, cobalt, iron and palladium followed by--or mixed with--a capture mass containing sulfur or a metal sulfide.

Process for elimination of mercury and possibly arsenic in hydrocarbons

The invention relates to a process for preparing a mercury collecting solid mass containing a carrier and copper, at least partly as copper sulfide, comprising the following steps of:

Processes for preparing and regenerating a copper containing mercury

The invention concerns a process for removing sulfur oxides and particularly sulfur dioxide contained in such gases as industrial fumes, wherein said gas is contacted with a solid absorbent containing magnesium oxide and at least one group VIII noble metal, in such conditions that the sulfur oxides are mainly fixed as magnesium sulfate, and then the used solid absorbent is regenerated by contact with a hydrogen sulfide-containing reducing gas.

Process for removing sulfur oxides from a gas by means of an absorption

There are described catalysts containing, as oxides, iron, chromium and potassium, the latter being optionally partly in form of kaliophyllite Al.sub.2 O.sub.3, 2 SiO.sub.2, K.sub.2 O, as well as lanthanum, in a proportion, calculated in oxide weight, of 1-15% with respect to the final catalyst. The presence in the catalyst of lanthanum oxide, optionally previously combined with cobalt or vanadium, at least in part in the form of a mixed oxide of the perovskite type, confers to the catalyst an improved activity and/or selectivity in dehydrogenation reactions, particularly of ethylbenzene to styrene.

Catalyst containing iron, chromium, potassium and lanthanum oxides, its

A process for manufacturing catalysts containing, as oxides, iron, chromium, potassium, as well as a rare earth metal in a proportion, calculated in oxide weight, of 1-15% with respect to the final catalyst, comprises:

Methyl ketones are prepared in liquid phase by oxidizing terminal olefins of the formula R--CH.dbd.Ch.sub.2, where R is a hydrocarbon radical. The oxidizing agent is hydrogen peroxide or an organic hydroperoxide, and the catalyst is a palladium catalyst of the formula Pd AA' where

Process for manufacturing methyl ketones by oxidation of terminal olefins

Methyl ketones are prepared in liquid phase by oxidizing terminal olefins of the formula R--CH.dbd.CH.sub.2, where R is a hydrocarbon radical. The oxidizing agent is hydrogen peroxide or an organic hydroperoxide, and the catalyst is a palladium catalyst of the formula Pd AA', (L.sub.m) where
