The catalytic oxidative coupling of methane: Ⅱ. Axial gas sample probing in a bubbling fluidized-bed reactor and the effect of side reactions

摘要

The atmospheric pressure catalytic oxidative coupling of methane was studied in detail by axial gas concentration probing experiments in a 60 mm OD bubbling fluidized-bed reactor system. Experimental data demonstrated a very fast reaction which occurred within the vicinity of the distributor(normally in the first 5 mm of bed height) under normal reaction conditions of 850deg and 83 vol/100/17 vol/100 CH_4/O_2 feed.
