Methyl tertiary-butyl ether adsorption

Isobutylene is the most chemically reactive of the butylene isopiers. If the objective is just to get the isobutylene out of the C4 stream, it can be removed by reaction with methanol (CH3OH) to make MTBE (methyl tertiary butyl ether), by reaction with water to make TBA (tertiary butyl alcohol), by polymerization, or by solvent extraction. After that, butene-1 can be removed by selective adsorption or by distillation. That leaves the butene-2 components, together with iso- and normal butane, which are generally used as feed to an alkylation plant. 

Study of adsorption of polar methyl tertiary-butyl ether (MTBE) and nonpolar 1- methylbutane vapors on activated carbons in the dynamic conditions was carried out by Gironi and coworkers [138]. The maximum capacities of activated... 

Pervaporation and adsorption studies performed in our group [36, 37] with methanol and methyl tertiary butyl ether (MTBE) molecules, showed that the silica membrane pores allowed the MTBE molecule ( 4.4 A) to permeate, though...
