Intensification of natural gas conversion to the key products of petrochemical synthesis and engine fuels

An analysis of technologies for producing engine fuels from natural gas is performed. Their main advantages and disadvantages are determined. A technology without feedstock recirculation for producing environmentally clean high-octane engine fuels and the key products of petrochemical synthesis (lower olefinic hydrocarbons, dimethyl ether, and methanol) is proposed. On the basis of laboratory and bench tests of the new process, mathematical models of a catalyst grain and catalytic reactors and the kinetic models of the reactions of the production of synthesis gas, methanol, dimethyl ether, olefins, and the components of engine fuels are constructed and their parameters are estimated. It is shown that the models are in agreement with experimental data. An energy and resource-saving scheme for producing engine fuels that ensures a decrease in the prime cost of the target products is calculated.
