Abstract

The oxidative coupling of methane to ethane and ethylene (C-2's) on lithium doped magnesia (Li/MgO) is carried out at reaction temperatures of 800circC. At these conditions the influence of non-catalytic reactions is investigated by varying the ratio of active catalyst to empty space in the reactor. At contact times shorter than 5 s there is no significant influence of non- catalytic reactions on the product selectivity. At longer contact times the post-catalytic space can benefit the ethylene yield by cracking of the ethane formed. However, it functions as an afterburner when oxygen is still present. The occurrence of the non-catalytic reactions has consequences for the reactor design.
