A process of manufacture of a solid catalyst made of a support coated with a thin catalytic layer and a process for eliminating gaseous and/or particulate pollutants in an exhaust gas. The process of manufacture includes preparing a solution A by dissolving alkoxide and/or chloride precursors of at least one metal selected from Al, Si, Ti, Zr, Fe, Zn, Nb, V and Ce in a solvent S1, preparing a solution B containing a surfactant, an organic acid, and/or hydrochloric acid (HCl) in a solvent S2, mixing solution A and solution B together, thereby obtaining a washcoat solution C, and dip-coating, drying, and calcinating the support into washcoat solution C. The processes provide for elimination of volatile organic compounds (VOCs), CO, and/or particulate pollutants in an exhaust gas.

A novel process can be used for producing methacrylates such as methacrylic acid and/or alkyl methacrylates, in particular MMA. The process leads to an increased yield and increased efficiency compared to other C4-based production processes, in particular processes starting from isobutylene or tert-butanol as raw material. The process can be operated for longer periods without disruption and with the same or even increased activities and selectivities. The process can also be executed in a manner that is as simple, cost-effective, and environmentally friendly as possible.

Disclosed are heterostructured silica catalysts (modified Haider heterostructured silica) and methods of their use and preparation. The heterostructured silica catalysts include a transition metal, an alkaline earth metal oxide, and silica, wherein the transition metal, the alkaline earth metal from the metal oxide thereof, and silicon (Si) from silica are each present in the crystal lattice structure of the catalyst. The catalyst can have application in, e.g., the hydrogenation of carbon monoxide.

A method for producing chemicals from crude oil by double-tube parallel multi-zone catalytic conversion is provided. The method may include the following steps: feeding the crude oil directly or separating the crude oil into light and heavy components by flash evaporation or distillation after desalination and dehydration; strengthening the contact and reaction between oil gas and catalyst by using two parallel reaction tubes with novel structure, controlling the reaction by zones, carrying out optimal combination on feeding modes according to different properties of reaction materials, controlling suitable reaction conditions for different materials, and increasing the production of light olefins and aromatics.
