摘要：Acid leaching residue of coal gasification slag (ALR-CGS) is a by-product of the aluminum extraction process of CGS. Its amount increased with the industrialization of the CGS aluminum extraction process. Thanks to the high silica content of ALR-CGS, this research evaluated the synthesis of MCM-41 using this discarded material. Highly ordered MCM-41 with hexagonal shaped pore diameters of 2.91-3.65 nm was synthesized using ALR-CGS following a non-hydrothermal sol-gel method. The synthesized sample had a BET specific surface area of 1347 m(2)/g. ALR-CGS is a very competitive alternative silica source in the synthesis of MCM-41. (C) 2016 Elsevier B.V. All rights reserved.
