| 英文摘要 | a series of ni-promoted w2c/activated carbon (ac) catalysts were investigated for the catalytic conversion of jerusalem artichoke tuber (jat) under hydrothermal conditions and hydrogen pressure. even a small amount of ni could greatly promote the conversion of jat to 1,2-propylene glycol (1,2-pg), whereas the pure w2c/ac catalyst resulted in the selective formation of acetol. the product distribution profiles involving the reaction temperature, time, and h2 pressure indicated that 1,2-pg formed as a result of acetol hydrogenation, which was catalyzed by ni. thus, there was a synergy between w2c and ni, and the best performance yielded 38.5?% of 1,2-pg over a 4?% ni20?% w2c/ac catalyst at 245 degrees c, 6 mpa h2, and 80 min. to understand the reaction process, some important intermediates, such as inulin, fructose, acetol, glyceraldehyde, and 1,3-dihydroxyacetone, were used as the feedstock. based on the product distributions derived from these intermediates, a reaction pathway was proposed, where jat was first hydrolyzed into a mixture of fructose and glucose under the catalysis of h+, then the sugars underwent a retro-aldol reaction followed by hydrogenation catalyzed by niw2c. |
