    摘要: Catalyst for dehydrogenating hydrocarbons, as manufactured by the process comprising:Admixing one or more iron compounds, chromium compounds and potassium compounds, in a definite range of relative proportions,Moistening and malaxing the resulting mixture while adding thereto a clayish material in such an amount as to obtain by reaction with the potassium compound, a proportion of 3 to 55% b.w. of potassium alumino-silicate in the final catalyst,Shaping the homogeneized resulting paste, drying and roasting it at about 870 - 1050.degree. C, the potassium compound being used in an amount greater than that liable to combine with the clayish material.

    摘要: A monolithic honeycomb-type structure useful in particular as a particle filter for exhaust gases from diesel engines has a number of passages that empty into the end faces of said monolith, but are alternately open and sealed. The monolith consists of a porous refractory material that comprises: 70 to 97% by mass of &agr; and/or &bgr; crystallographic-type silicon carbide that has at least one particle size and preferably at least two particle sizes, and 3 to 30% by mass of at least one bonding ceramic phase in the form of a micronic powder or particles that are obtained by atomization, comprising at least one simple oxide, for example, B2O3, Al2O3, SiO2, MgO, K2O, Li2O, Na2O, CaO, BaO, TiO, ZrO2 and Fe2O3 and/or at least one mixed oxide, for example, the alkaline aluminosilicates (of Li, Na, or K) or alkaline-earth aluminosilicates (of Mg, Ca, Sr or Ba), clays, bentonite, feldspars or other natural silico-aluminous materials. The production of the monolith comprises a calcination stage under an oxygen-containing atmosphere at a temperature up to 1650° C., but less than 1550° C.

    摘要: A solid mass for the recovery of mercury, comprising a solid mineral support or dispersant, essentially copper and sulphur at least partly in the form of copper sulfide is produced by the following stages:a) at least one copper compound other than a sulphide is incorporated into a solid mineral dispersant or carrier,b) the product obtained in stage (a) is calcined in order at least partly to convert the copper compound or compounds which it contains into copper oxide (CuO and/or Cu.sub.2 O),c) the product obtained in stage (b) or in stage (a) if there has not been a stage (b) is brought into contact with elementary sulphur,d) the product resulting from stage (c) referred to as the precursor, is subjected to a thermal treatment in a non-oxidizing atmosphere and accompanied by gas scavenging, to a temperature and for a sufficient time to allow the formation of sulphide of the metal(s) present.

    摘要: The invention relates to a process for the production of hydrogen by steam reforming of methanol, in which water and methanol are reacted (4), under relatively high pressure, over a suitable catalyst. The gases emitted from the reaction are contacted (10), after condensation (7) under relatively high pressure, with an adsorption agent, such that the byproducts of the reaction are adsorbed and a hydrogen-rich gas is liberated (11). Also, byproducts which are recycled to the steam reforming reactor (4), are periodically desorbed under relatively low pressure at along with a fraction of the hydrogen present in the adsorption zone (10), after being submitted to recompression (13) and removal (14), under relatively high pressure, of at least a portion of carbon the dioxide, the desorbed gas fraction is recycled to the steam reforming reactor.
