A method of preparing hydrodesulfurization catalysts having cobalt and molybdenum sulfide deposited on a support material containing mesoporous silica. The method utilizes a sulfur-containing silane that dually functions as a silica source and a sulfur precursor. The method involves an one-pot strategy for hydrothermal treatment and a single-step calcination and sulfidation procedure. The application of the hydrodesulfurization catalysts in treating a hydrocarbon feedstock containing sulfur compounds to produce a desulfurized hydrocarbon stream is also specified.

Exemplary oxygen carrier particles may comprise a mesoporous support and a plurality of metal oxide-based nanoparticles immobilized on the mesoporous support. The plurality of metal oxide-based nanoparticles may comprise 10 volume percent to 80 volume percent of mesopores in the mesoporous support. A reactor may comprise a feedstock inlet in fluid communication with a carbonaceous feedstock source, a product stream outlet, and oxygen carrier particles. Exemplary reactors may be operated by providing a carbonaceous feedstock to an inlet of the reactor, providing oxygen carrier particles within the reactor, and collecting a product stream from an outlet of the reactor.

Disclosed is a method for preparing a synthesis gas. The method may include performing a combined reforming reaction by injecting a reaction gas including water (H.sub.2O) and heat-treating it in the presence of the catalyst. The catalyst may include a mesoporous support including regularly distributed mesopores, metal nanoparticles supported on the support, and a metal oxide coating layer coated on a surface of the support.

The present invention relates to a dielectric barrier discharge (DBD) plasma reactor comprising a catalyst bed for CO.sub.X hydrogenation in a discharge region; and a method to produce light hydrocarbons from a CO.sub.X-containing gas mixture in the DBD plasma reactor. In the DBD plasma reactor for a CO.sub.X hydrogenation reaction, the catalyst for CO.sub.X hydrogenation comprises a catalytically active component on a mesoporous support that is a dielectric. When the DBD plasma reactor for a CO.sub.X hydrogenation reaction according to the present invention is used, it is possible to convert by-product gases or waste gases into higher-value-added chemical products without additional heat supply from the outside.
