[中文文摘]针对三种不同物料连续流动催化反应系统:(1)MoVTeNbO/SiO_2用于丙烷选择氧化制丙烯醛反应;(2)KMoNi/SiO_2用于高硫合成气制甲硫醇反应;(3)MoNiP/Al_2O_3用于噻吩加氢脱硫反应。在各自的固定反应条件下,研究催化反应转化率与催化剂组分含量的关系,提出半经验表达式:x_A=1-exp[-G(w_i)],G(w_i)=。利用此式拟合上述3个催化反应系统的实验数据,平均相对偏差分别为1.97%,1.54%和1.42%,拟合精度较高,证明所提出的关系式是合理的,而且颇有普适性,可用于优化设计催化剂组分的含量。[英文文摘]Relationship of conversion to catalyst contents was studied for three different material catalytic reaction systems with continuous -flow of reactants as follows:(1) MoVTeNbO/SiO_2 catalysts for selective oxidation of propane to acrolein;(2) KMoNi/SiO_2 catalysts for methanethiol synthesis from high H_2S-containning synthesis gas;(3) MoNiP/Al_2O_3 catalysts for thiophene hydrodesulfurization. A semiempirical expression of relationship of conversion to catalyst contents was put forward and used to correlate the experimental data of the above reactions.Average relative deviation(ARD) are 1.97%,1.54%and 1.42% respectively. The high fitting precision indicates that the expression proposed is reasonable,widely applicable and can be used for optimizing component contents of catalysts.国家重点基础研究发展计划(973计划,2004CB217805); 福建省百千万人才工程(闽人办[2003]40号)
