1-Butene conversion reactions over SAPO-11 and MeAPO-11 were studied under 0.2 bar 1-butene partial pressure. High conversion (90%) and high selectivity (40%) toward isobutene can be obtained. The selectivities of isobutene increase with increasing temperature and contact time. The deactivations of SAPO-11 and MeAPO-11 ( Me = Zn, Co, Mn) are not serious.
