Safety isobutane alkylation

For alkylating isobutane, considerable research has been conducted to develop processes that use solid catalysts. Safety problems would then be significantly reduced, but no known process has yet been commercialized. In all cases, the catalysts were rapidly deactivated in hours or even minutes. Conjunct polymers were obtained that diffuse most slowly from the pores (1,35). These polymers adsorb on the inner surfaces of the pores.
