Abstract

While the production of biodiesel increased, significant amounts of glycerol, a byproduct that will become abundant if large scale bio-diesel production is implemented. The glycerol byproduct amount to about 10 wt% of the total biodiesel produced. Rather than consider the crude glycerol as a waste as a result of the increased amount of glycerol byproduct, many research being done to convert glycerol to value added products. There is no previous study on the direct conversion of glycerol to methanol. Therefore, this preliminary work studied the effect of metal loading on zeolite on the conversion and yield of methanol. Zeolite HZSM-5 was loaded with different amount of Nickel and Copper. The experiments were carried out in the presence of Nitrogen as carrier gas by using fixed bed reactor at 500oC and atmospheric pressure. The catalysts were characterized by XRD while the products were analyzed by GC-FID for calculation of conversion and yield of methanol. The results from the experiments suggested that Cu/HZSM-5 had the highest conversion and methanol yield with 100% and 6.70% respectively.

在沸石基催化剂的存在下，甘油转化为甲醇

当生物柴油的产量增加时，大量的甘油，一种如果大规模生物柴油生产将变得丰富的副产品。甘油副产物约占所生产生物柴油总量的10%。由于甘油副产品数量的增加，人们不再将粗甘油视为废物，而是进行了许多将甘油转化为增值产品的研究。关于甘油直接转化为甲醇的研究尚无先例。因此，本初步工作研究了沸石上金属负载对甲醇转化率和收率的影响。以HZSM-5型沸石为研究对象，分别负载不同量的镍和铜。实验采用固定床反应器，以氮气为载气，在500℃常压条件下进行。用XRD对催化剂进行了表征，并用GC-FID对产物进行了分析，计算了甲醇的转化率和收率。实验结果表明，Cu/HZSM-5的转化率和甲醇收率最高，分别为100%和6.70%。
