Abstract
A process for preparing a pillared interlayered clay comprises heating a smectite clay containing material with a solution comprising a polymeric cationic hydroxy metal complex of a suitable metal (preferably aluminum) and a surfactant having the formula of R.sup.1 --O--(CHR.sup.2 --CHR.sup.2 O).sub.x H, wherein, R.sup.1 is an aliphatic C.sub.6 H.sub.13 --C.sub.24 H.sub.49 hydrocarbyl radical, R.sub.2 is hydrogen or the methyl group, and x is about 3-7. The thus prepared pillared interlayered clay exhibits high surface area, high methane storage capacity and high resolution in separating gaseous hydrocarbons.
