Aromatic Compounds Production from Sorbitol by Aqueous Catalytic Reforming

The rules on regulating aromatic compounds production was investigated by aqueous cat-alytic reforming of sorbitol. It was found that aromatics, ketones, furans, organic acids were main compounds in organic phase. The obvious e ect of metal content showed that the highest carbon selectivity of aromatics was 34.36% when 3wt% Ni content was loaded on HZSM-5 zeolite modi ed by MCM-41. However, it was decreased only to 4.82% when Ni content was improved to 20wt%. Meanwhile, di erent reaction parameters also displayed important impacts on carbon selectivity. It was improved with the increase of temperature, while it was decreased as liquid hourly space velocity and hydrogen pressure was increased. The results showed that appropriate higher temperature, longer contact time and lower hy-drogen pressure were in favor of aromatics information, which suggested a feasible process to solve energy crisis.
