【甲烷氧化偶联OCM反应低温型Fe-P-O体系催化剂的研究】肖承庆.pdf

报要本文以开发适合于较低温度下(700℃),能够有效进行甲统氧化偶联反应的催化剂为主要目的,研制了Pe-P-0体系低温型催化剂,并对该体系催化剂过了系统地研究.在对系催化剂制备条件影响因素进行了考察,确定了最佳制备条件后,制备re/P(摩尔比)变化的一个系列催化剂,在常压固定床反应器中,以共同进料的操作方式(稳态)进行催化剂评价,确定Fe/P=0为催化剂的最佳组份配比。对反应条件进行考察后,适宜反应条件为常压下,反应温度为650℃,CH/0/Ar(体积比)=2/1/2,G.H.S.V=3000h-2,此条件下反应,0Fe/P催化剂甲烷转化率10.
