The pseudomorphic transformation of spherical silica gel (LiChrospher® Si 60) into MCM-41 was achieved by treatment at 383 K for 24 h with an aqueous solution of cetyltrimethylammonium hydroxide (CTAOH) instead of hexadecyltrimethylammonium bromide

It was shown in previous publications that porous glasses can be transformed into MCM-41 materials with monomodal or bimodal (hierarchical) pore systems. In this study we describe the synthesis of MCM-48 granules with a bimodal pore structure via pse

In this study, the adsorption of CO2 and H2S has been investigated on commercial activated carbon Desorex K43 impregnated with K2CO3, NaOH, or Fe2O3 in order to assess their potential for “upgrading” and desulfurization of biogas or contaminated
