葡萄糖加氢制山梨醇Ru/C催化剂的开发实践探究

To Explore the Development Practice of Ru/C Catalyst for Hydrogenation of Glucose to Sorbitol

以葡萄糖加氢制山梨醇反映中对制备高活性Ru/C催化剂的方法进行研究。对活性组分负载方式、钌负载量、活性炭载体处理、氯离子脱除等对催化活性的影响。研究结果显示,钌晶粒可由尿素均匀沉淀法获得;双氧水处理活性炭的效果最好;钌晶粒的分散度随着洗涤脱氯而增加,催化剂活性提高。

Hydrogenation of Glucose Sorbitol reflected in the study of methods for producing high active Ru / C catalyst. Effect of active ingredient load mode, ruthenium loading, vehicle-treated activated carbon, chloride removal, etc.on the catalytic activity of the right. The results show that ruthenium crystal grains can be obtained by homogeneous precipitation of urea; hydrogen peroxide and activated carbon was the best; dispersion of ruthenium grains with washing dechlorination increases the catalytic activity is improved.
