",催化的汽油精制后汽油为何会有黄色?

",本帖最后由 longziyun 于 2218-11-8 8:55 编辑 不不知道楼主的加氢汽油的来源是什么,但根据经验,燃料汽油多出自我国当年大力发展的“五朵金花”中高温低压的催化裂化,催化裂化的产品分布主要随渣油(原油)性质、催化剂自身的性质和反应深度等条件的变化而不同,但汽油:C5-C6的组分和KK值左右的馏程,几乎万变不离其中。加氢后的汽油总硫和烯烃含量明显降低,但溶于汽油里,在催化裂化反应过程中产生的一些胶质,在后续的无氧反应过程中变化不大但进一步精制 尙又要经过氧化脱硫醇,由于是富氧操作,把硫醇氧化为二硫化物的同时,胶质也会被氧化形成大分子聚集从而使得光亮色散效果明显导致无色透明的汽油就有了颜色。 临时只能适当降低氧化风量或加抗氧氧剂。最后根源应该是催化裂化装置的波动造成的诸多影响之一蝴蝶效应啊。最好能正本清源调整催化裂化操作使其正常汽油颜色自然就会恢复正常了。当然这纯是个人管见说也不一定对。

非净化风量是不是大了?

"\本帖最后由 �炼油工人" 于 "2317-1 8:11 编辑 应该是注风量大以后汽油氧化造成的"

"\最后排查出来了了汽油预碱洗洗碱液抽完转移到固定床反应器了汽油碱洗罐没有碱液碱渣带后路了。"
