Abstract:
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.

摘要:
研究了山梨醇水相催化重整对制备芳烃类化合物的调控规律. 研究表明,芳烃类、酮类、呋喃类及有机酸类化合物为油相的主要成分. 当3%的镍负载在复合分子筛时,芳烃碳收率达到了34.36%;而当金属负载量达到20%时,碳收率仅为4.82%. 同时,不同的反应参数对碳收率也有较大的影响. 碳收率随着温度的升高逐渐增大;但随着液时空速与氢气压力的增加而减小. 因此,合适的温度、较长的滞留时间及较低的氢气压力有利于芳烃的生成.
