甲缩醛合成流化催化精馏过程的非平衡级模拟

STIMULATION OF FLUIDIZED CATALYTIC REACTION DISTILLATION FOR SYNTHESIS OF METHYLAL USING NONEQUILIBRIUM STAGE MODEL

以酸性离子交换树脂为催化剂、在筛板塔内进行甲缩醛合成流化催化精馏过程，建立了非平衡级模型，采用ＮｅｗｔｏｎＲａｐｈｓｏｎ方法进行了模拟计算，得到了催化精馏塔内温度、浓度和流率等的分布规律。

A nonequilibrium stage model was established for the synthesis of methylal by fluidized catalytic reaction distillation using a kind of acidic ion exchange resin as catalyst in a sieve tray column. The model was resolved by Newton Raphson method. The distributions of concentration, temperature and flow rate in column were found. A suitable technological condition for this process was selected.
