摘要

实验研究了合成甲醇固定床反应器流向变换强制周期操作的非定态特性

考查了流向变换周期、进料流速和进料组成对床层轴向温度分布、热波在床层内的爬行速度以及反应器流出物组成的影响 .研究发现

即使进料中∑COx 总浓度降低至 0 .33 % (mol)

合成甲醇的非定态反应过程也能自热进行

Abstract

Unsteady-state performance of a fixed bed reactor for methanol synthesis

operating under flow reversal mode

was experimentally studied.The effects of various factors

such as feed gas velocity

feed composition and cycle duration on the transient axial temperature profile in the bed

propagation velocity of thermal wave

transient composition of tail gas and time-averaged methanol output were investigated at a pressure of 2.0 MPa

gas velocity about 0.20-0.50m·s -1

cycle duration of 20-120?min and total concentration of carbon oxides

∑CO x

0.33?%-7.32%mol.Higher conversion of ∑CO x than that of steady-state operation was achieved even though for a very low concentration of ∑CO x down to 0.33%mol.
