Oxidative coupling of methane over Li/Sn/MgO catalysts. Use of a fluidized bed reactor at low gas velocities

摘要

A fluidized bed reactor has been used to carry out methane oxidative coupling (MOC) over a Li/Sn/MgO catalyst. The influence of the operating conditions. (CH_4/O_2 ratio, total floware, temperature, particle size) has been studied, with most of the experiments concentrated in the region of low fluidizing velocities. In this work, hydrocarbon yields around 20 percent have been obtained, which are among the highest reported for this type of reactor using undiluted CH_4/O_2 mixtures.
