Modeling and Simulation of Catalytic Direct Partial Oxidation of Methane to Methanol in a Fluidized-Bed Reactor

Autor: Asghar Mohammadi, Ali Farzi

Publikováno v: مجله مدل سازی در مهندسی, Vol 16, Iss 52, Pp 397-407 (2018)

Direct catalytic oxidation of methane to methanol is a novel technique which has eliminated the intermediate and expensive process of synthesis gas production. This technology can be used for low deposit, remote, low-pressure fields, and abundant res
