空间位阻苯酚烷基酯及其制备方法与应用

, 2016
本发明公开了一种空间位阻苯酚烷基酯、其制备方法与应用。该制备方法包括：在复合碱催化剂存在的条件下，使烷基丙烯酸酯与烷基苯酚化合物反应，再加入高分子量醇类化合物进行酯交换反应，生成位阻苯酚烷基酯化合物，而后用含水无机酸与有机酸组成的混合酸中和任何的催化剂残留物，以生成沉淀的盐和-或油溶性有机酸盐，然后分离出沉淀的盐，获得空间位阻苯酚烷基酯。本发明在位阻苯酚酯的制备过程中，采用复合碱催化剂提高了催化效率，并采用一釜反应方式简化了操作过程，缩短了反应时间，同时还利用混合酸中和的方法简化了催化剂中和及除去过程 ...

温度和停留时间对煤热解挥发分二次反应的影响

, 2018
在两段固定床反应器中考察了温度和停留时间对煤热解挥发分二次反应产物分布的影响.结果表明,温度和停留时间对二次反应的影响相互关联.温度≤600℃、停留时间小于2 s时,挥发分基本不发生气相二次反应.随温度升高和停留时间延长,挥发分二次反应加剧,焦油产率下降,气体产率和积碳产率增加.温度低于700℃时,焦油主要转化为气体产物,气相二次反应由二次裂解反应控制;高于700℃时,焦油转化为气体和积碳,气相二次反应由裂解反应和结焦反应共同控制.提高二次反应温度和延长停留时间,热解气中的H_2 ...
