Brief description: A group of technological processes based on direct oxidation of various hydrocarbon gases has been developed at IPCP RAS, which provides various oxygenates, including alcohols (methanol, ethanol), aldehydes (formaldehyde, acetaldehyde), acids (acetic acid), as well as olefins (ethylene, propylene), etc., in a simple one-step non-catalytic gas phase process. As far as the process is one-step, simple and technologically flexible, and no catalysts, and, hence, strict requirements to gas preparation and to its composition are necessary, it is economically more effective in small-capacity mode than traditional technologies for these products. This technology is much more efficient than all available foreign ones. By taking into account fundamental kinetic features of the process mechanism, the gas conversion and yield of the target products have been increased by several times, the process pressure has been decreased, the range of hydrocarbon gases for processing has been extended, and some new modifications of the process and fields of its application have been proposed.
