Abstract:: ... Activated carbon is functionalized by different treatments with sulfuric acid and hot liquid water and used as catalyst for the hydrolysis of cellobiose in a continuously operated fixed bed reactor. Characterization results reveal that the chemically treated materials are more disordered with a lower degree of graphitization, while adsorption isotherms demonstrate that van der Waals forces dominat ...

Abstract:: ... The sulfuric acid-catalyzed conversion of paper wastes in gamma-valerolactone (GVL) or dioxane leads to the formation of levulinic acid (LA) and formic acid (FA), which can be converted to GVL by transfer-hydrogenation using the Shvo catalyst in situ or separately. The isolation of LA and FA was assisted by the neutralization of the sulfuric acid with ammonia to form a biphasic system. While the a ...
