摘要：在内循环无梯度反应器中研究了铜系催化剂氯乙烯非汞合成的反应特性。在转速为1 000~4 000 r/min,乙炔空速80~170 h^(-1),乙炔和氯化氢物质的量比为0.5~2.0,反应温度180~300℃的实验条件下,考察了转速、空速、原料配比和反应温度对氯乙烯非汞合成反应的影响。选取幂函数动力学模型,根据实验数据,运用线性最小二乘法,回归得到表观活化能为28 k J/mol,C_2H_2的反应级数为1.43,HCl的反应级数为2.11。残差分析和统计检验表明,动力学模型是适定的。
The reaction characteristics of acetylene to vinyl chloride over copper-based non-mercury catalystwere studied in a non-gradient inner loop reactor. The experiment was performed at the stirring speed of1 000-4 000 r/min, acetylene space velocity of 80-170 h-1, molar ratio of acetylene to hydrogen chlorine of0.5-2.0, reaction temperature of 180-300 ℃. An exponential kinetic model was established and the linearleast squares method was used to estimate parameters of the proposed models based on the experimental data.The calculation showed that activation energy was 32.87 kJ/mol and reaction orders were 1.43 for acetyleneand 2.11 for hydrogen chloride, respectively. The residual error analysis and the statistic tests showed thatthe proposed macro-kinetic model was reliable and adequate.
