The invention relates to a method for the production of a TiOmaterial comprising: The invention also relates to a TiOmaterial exhibiting an absorbance in the visible spectrum and in particular a light absorption at 500 nm which is greater than 50% of the light absorption at 400 nm, and its use as photocatalyst for the degradation of pollutants in air or water and water splitting into H, under radiation in the visible spectrum.

[object Object]

The invention relates to a cyclical method for producing a nitrogen fraction, the purity of which is greater than or equal to 95 mol %, and a hydrocarbon-enriched fraction from a filler containing nitrogen and a hydrocarbon, said method using a specific class of porous hybrid solids as an adsorbent in a pressure-swing adsorption (PSA) process. The invention also relates to equipment for implementing said method.

Cyclical method of producing high-purity nitrogen and optionally a high-purity hydrocarbon from a feedstock containing nitrogen and a hydrocarbon

Catalytic process for the partial conversion of a gaseous mixture containing carbon monoxide and hydrogen into a mixture of hydrocarbons, including bringing the said gaseous mixture into contact with a solid catalyst, the solid catalyst having a porous support with a composite material including SiC and a titanium carbide and/or a titanium oxide, and an active phase. The support is prepared in the form of grains, beads, or extrudates, or in the form of cylinders or sheets of cellular foam.

Catalytic process for the conversion of a synthesis gas to hydrocarbons

The invention relates to a process for manufacturing porous materials, which comprises the following steps: preparation of a solution of at least one structuring agent, having at least two structuring parts linked by at least one type of reversible non-covalent interaction; formation of the structured or porous material; separation of the at least two parts of the structuring agent at low temperature; and recovery of at least 50% by weight of the two non-degraded structuring parts and the porous material.

Impure gas streams containing contaminating amounts of NO.sub.x, e.g., automotive exhaust fumes and industrial waste gases, are purified by contacting same, in the presence of ammonia, at an elevated temperature, with a catalyst composition which comprises an inorganic oxide support substrate having a catalytically effective amount of a metal oxide active phase deposited thereon, such support substrate comprising at least one alumina, aluminate, titanium dioxide and/or zirconium dioxide and such catalytically active phase comprising at least one vanadium oxide and/or molybdenum oxide and/or tungsten oxide, the surface of the support substrate being chemically bonded to the metals V and/or Mo and/or W and the catalyst being devoid of V.sub.2 O.sub.3 and/or MoO.sub.3 and/or WO.sub.3 crystalline phases, and thereby selectively reducing such NO.sub.x values while minimizing the formation of N.sub.2 O.

V/Mo/W catalysts for the selective reduction of nitrogen oxides

Novel catalysts that include a porous alumina support having a surface coating of at least one spinel compound thereon, e.g., a compound having the formula M.sup.1 Al.sub.2 O.sub.4, and a catalytically active phase deposited onto such coated support, e.g., a catalytically active metallic oxide, are well adopted for the catalytic ammonia reduction of NO.sub.x values contained in gaseous flowstreams thereof, which gaseous flowstreams typically also contain SO.sub.x values.
