ABSTRACT:
A process for using hydrogen-containing gas to regenerate a zeolite catalyst comprising at least some crystalline aluminosilicate zeolitic material having pore windows formed by 8-membered rings of oxygen atoms, e.g., ZSM-34, which has been used to promote conversion of methanol and/or methyl ether to light olefins. Contact of such catalysts with hydrogen-containing gas such as hydrogen or synthesis gas at particular regeneration temperatures and pressures can restore the activity of such catalysts either in the presence or absence of organic reactants without forming potentially catalyst-damaging by-products such as water.
