Methyl tertiary butyl ether (MTBE) has been accepted worldwide as an octane booster, and the demand for MTBE has grown rapidly as the use of tetraethyl lead and similar lead containing compounds have been phased out due to concerns about the effect of lead compounds on health. MTBE is formed by the reaction of isobutene with methanol, an acid cation exchange resin as often with catalyst. In this study, the catalytic activity of a zeolite, H-ZSM-5, was evaluated in a fixed-bed micro-reactor at 75 to 115/degree/C. Isobutene conversions ranged from 10 to 89/percent/ and were completely selective to the formation of MTBE. Dimer formation was hindered by the unique pore size of the zeolite. Temperature and isobutene-to-catalyst ratio were the significant process variables. Pressure had no significant effect on conversion of the liquid phase reaction. The reaction rate was zero order with respect to methanol concentration and was correlated by a first order reversible reaction equation. This zeolite may have selectivity and stability advantages over the present commercial catalyst. 12 figs., 5 tabs.
