An apparatus for forming C1 to C5 alcohol, carboxylic acid, or mixture thereof from carbon dioxide and hydrogen is described. The apparatus comprises: a dielectric barrier discharge, DBD, device arranged to generate a plasma; and a passageway having an inlet for the carbon dioxide and the hydrogen and an outlet for the C1 to C5 alcohol, carboxylic acid, or mixture thereof and including therein a catalyst comprising nickel and/or cobalt and/or copper on a support. The passageway extends, at least in part, through the DBD device wherein, in use, the carbon dioxide is exposed to the catalyst in the presence of the hydrogen in the generated plasma, thereby forming the C1 to C5 alcohol, carboxylic acid, or mixture thereof from at least some of the carbon dioxide and the hydrogen. The DBD devices comprises a water electrode. A method and a catalyst are also described.

A process for preparing C2 to C3 hydrocarbons may include introducing a feed stream including hydrogen gas and a carbon-containing gas comprising carbon monoxide, carbon dioxide, and mixtures thereof into a reaction zone of a reactor, and converting the feed stream into a product stream comprising C2 to C3 hydrocarbons in the reaction zone in the presence of a hybrid catalyst.

Disclosed are a spherelike supermacroporous mesoporous material, a polyolefin catalyst, and a preparation method therefor and an olefin polymerization process. The spherelike supermacroporous mesoporous material has a twodimensional hexagonal ordered pore channel structures. The mesoporous material has an average pore size of 10 nm to 15 nm, a specific surface area of 300 m.sup.2/g to 400 m.sup.2/g, and an average particle size of 1 .Math.m to 3 .Math.m, based on the total mass of the mesoporous material. The mass content of water in the mesoporous material is < 1 ppm. The mass content of oxygen in the mesoporous material is < 1 ppm. When a polyolefin catalyst prepared with the mesoporous material as a carrier is used for an olefin polymerization reaction, the a polyolefin product with a narrow molecular weight distribution and a good melt index can be obtained.

The present disclosure concerns a process for converting alkyl halides to ethylene and propylene, said process comprising the steps of (a) providing a feedstream comprising alkyl halides; (b) providing a first and second catalyst composition, said second catalyst composition comprising a cracking catalyst; (c) contacting said feedstream with said first catalyst composition in a first reaction zone under first reaction conditions to provide a first product stream, and (d) subjecting at least a part of said first product stream to an Olefin Catalytic Cracking with said second catalyst composition in a second reaction zone under second reaction conditions to provide a second product steam. The process is remarkable in that it further comprises a step of steaming said first catalyst composition before the step (c) and in that said first catalyst composition comprises zeolites and a binder, wherein said zeolites comprise at least one 10-membered ring channel.

An ammonia production method is a method of producing ammonia from nitrogen molecule using electron supplied from a power supply in the presence of a complex and a proton source. The complex used is, for example, a molybdenum complex (1) that is carried on Merrifield resin. The proton source used is an electrolyte membrane, a solution used in a cathode tank, or both the electrolyte membrane and the solution used in the cathode tank:
