It is found that the macroscopic kinetics for ethylbenzene synthesis can be described by the law of consecutive-parallel reaction kinetics over the modified industrial PMg ZSM-5 catalyst made by the authors. The macroscopic kineties model is as follows: (-r_B)=-(dp_B)/dt=k_1p_B~(0.5)p_(Et)~(1.07) r_(EB)=(dP_(EB))/dt=k_1p_B~(0.5)p_(Et)~(1.07)-k_2p_(EB)~(0.2)P_(Et)~(1.07) r_(DEB)=(dp_(DEB))/dt=k_2p_(EB)~(0.2)p_(Et)~(1.07)

在自制的磷镁改性ZSM-5分子筛工业催化剂上,通过大量实验与数据处理,指出,苯与乙醇合成乙苯的宏观动力学可用连串-平行反应力学规律描述,其动力学模型为:(-γ_B)=-dP_B/dt=k_1P_B~(0.5)P_(Et)~(1.07),γ_(EB)=dP_(EB)/dt=k_1P_B~(0.5)P_(Et)~(1.07)-k_2P_(EB)~(1.07),γ_(DEB)=dP_(DEB)/dt=k_2P_(EB)~(0.2)P_(Et)~(1.07)。

Effects of hydrogen sulfide on alkylation of benzene with ethylene over catalyst FX-02 were studied. It implied that sulfide hydrogen sulfide had occupied the active sites of the catalyst and impeded the adsorption and reaction of reactants. Thus the desulfuration of FCC off-gas is necessary in the process of ethylbenzene synthesis using FCC off-gas as feedstock over catalyst FX-02.

研究了H2 S对FX -0 2催化剂上苯与稀乙烯烷基化反应的影响。认为是H2 S占据了催化剂的活性位 ,妨碍了反应物的吸附和反应。结果表明 ,在FX -0 2催化剂上利用干气制乙苯时 ,应对干气进行脱硫预处理。

Some technologies of ethylbenzene synthesis on zeolite are reviewed and their advantages and disadvantages are compared in this paper.The research situation in recent years and the developing trend of alkylation catalysis technology are described emphatically.It is considered that restraining the deactivation by coking of zeolite catalyst and controlling the generation of xylene are keys of improvement of ethylbenzene technology.

综述了乙苯生产技术的进展 ,比较了分子筛催化合成乙苯几种生产工艺的优缺点以及研究现状与发展趋势 ,指出抑制催化剂结焦和二甲苯的生成是改进乙苯工艺和开发新一代催化剂的关键。
