Production Process of MCM-41 and SBA-15 MOLECULAR FEATURES FROM RECYCLED GLASS

摘要

process of producing mcm-41 and sba-15 molecular sieves from recycled glass powder. The present invention provides reactive silica production processes and processes for producing mcm-41 and sba-15 molecular sieves from glass dust. mcm-41 and sba-15 molecular sieves are mesoporous silicates widely used in processes of oil adsorption, cracking and refining, biodiesel synthesis and fischer-tropsch synthesis. The present invention describes synthesis methodologies for the molecular sieves mcm-41 and sba-15 from a route that reduces their production costs, in an initial estimate by about 20% to 40%, replacing conventional silica sources with vitreous waste (glass dust) that has low economic value and high ecological value because it is the recycling of an industrial waste.
