摘　　要：用滴流床反应器代替原有的鼓泡塔式反应器，进行亚硝酸乙酯（简称亚酯）再生试验研究，采用惰性瓷环和分子筛为填充介质，考察了工艺条件，如原料气进气方式、反应温度和NO／O2体积比对O2转化率的影响。试验发现填充介质采用碗状瓷环为最佳，适宜的工艺条件：反应温度范围在40～60℃之间，NO／O2的摩尔比为6：1，惰性气体N2的体积分数为50％。The trickle bed reactor was used to replace the bubble bed reactor for ethyl nitrite regeneration. Inert porcelain and molecular sieve were selected as the filling material for testing the effects of parameters such as mode of gas inlet, reaction temperature and mole ratio of NO/O2 on conversion of O2. It was found that inert porcelain is the best filling material for this reaction and the suitable reaction condition is： temperature of 40-- 60℃, mole ratio of NO/O2 is 6：1 and content of N2 is 50% .
