LIGNOCELLULOSIC BIOMASS WASTE AS PRECURSOR FOR THE PREPARATION OF ACTIVATED CARBON MONOLITHS FOR ALCOHOL DEHYDRATION
DME is recognized as a clean diesel substitute and a key intermediate for other important chemicals,such as olefins,methyl acetate and dimethyl sulphate.DME can be obtained by methanol dehydration reactions using acid catalysts such as zeolite materials,T-Al2O3 and acid modified T-Al2O3.In this sense,chemical activation with phosphoric acid is able to provide activated carbons with a high development of the porosity,relatively high oxidation resistance and a great presence of low-moderate acidic sites [1].In this work,activated carbon monoliths(ACMs)from different lignocellulosic biomass waste have been prepared by the direct extrusion of the precursors with phosphoric acid,followed by activation under inert atmosphere,and washing with distilled water.These ACMs were used as catalysts for different alcohol dehydration reactions.
