Author: Fokin, I. G., Ozerskii, A. V., Nikitin, A. V., Savchenko, V. I., Arutyunov, V. S., and Sedov, I. V.
Subjects: *PARTIAL oxidation, *METHANE, *HYDROGEN, *OXIDATION of carbon monoxide, *NATURAL gas, *PRESSURE
Abstract: The effect of carbon monoxide and hydrogen additions on partial gas-phase high-pressure oxidation of methane was studied experimentally. The maximum permissible concentrations of these components in the recycled gas were determined. The optimum multiplicity of the hydrocarbon gas recycling in the process was substantiated.

Subjects: *OXIDATION of methanol, *NATURAL gas, *PARTIAL oxidation, *METHANOL as fuel, *CARBON monoxide, *METHANOL, *OXIDIZING agents
Abstract: Various options for designing the direct oxidation of natural gas to methanol are considered: flow-through, with a distributed supply of the oxidizer along the length of the reactor, and circulation. For each of the considered options for designing the process, the methanol yield was calculated, as well as the parameters at which the resulting blow-off gas can be used as a fuel. The optimal recycling rate in the circulation process has been determined. [ABSTRACT FROM AUTHOR]

Subjects: *PETROLEUM refineries, *PETROLEUM industry, *OXIDATIVE dehydrogenation, *GAS mixtures, *ETHYLENE, *HYDROCARBONS, *ALKANES, *PROPANE
Abstract: Trials of oxidative cracking of ethane—propane—n-butane mixtures were performed on an installation with the productive capacity with respect to the gaseous feed of 5 m3 h−1. Ethylene, CO, and hydrogen are the major products of oxidative cracking of oil refinery gases; their total yield can exceed 90%. The yield of ethylene and CO is determined by the total concentration of alkanes in the mixture and is independent on the length of their hydrocarbon chain, whereas the hydrogen yield appreciably decreases with an increase in the alkane chain length. The trials demonstrated high efficiency of the production of ethylene, CO, and hydrogen by oxidative cracking of oil refinery gas mixture components. [ABSTRACT FROM AUTHOR]

Subjects: *ETHYLENE, *HYDROGEN, *CRACKING process (Petroleum industry), *PETROLEUM refineries, *CARBON monoxide
Abstract: Flowsheets based on the results of experimental studies and detailed kinetic modeling were suggested for oxidative cracking of oil refinery gas components to obtain ethylene, CO, and hydrogen. The calculations show that oxidative cracking alone does not allow production of ethylene and СО in ratios required for the further catalytic carbonylation and hydroformylation of ethylene. Matrix conversion of a part of oxy-cracking products is suggested as an additional step for producing CO and hydrogen. [ABSTRACT FROM AUTHOR]
