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。
Aiming at the continuous flow catalytic reaction system of three different materials: (1) MoVTeNbO / SiO_2 is used in the selective oxidation of propane to acrolein; (2) KMoNi / SiO_2 is used in the reaction of methanethiol with high sulfur synthesis gas; (3) MoNiP / Al_2O_3 for thiophene hydrodesulfurization reaction. Under the condition of each fixed reaction, the relationship between the conversion rate of catalytic reaction and the content of catalyst components was studied, and the semi-empirical expression was proposed: x_A = 1-exp [-G (w_i)], G (w_i) =. The experimental data of the above three catalytic reaction systems were fitted by this equation, the average relative deviations were 1.97%, 1.54% and 1.42%, respectively. The fitting accuracy was high, which proves that the proposed formula is reasonable and quite universal Can be used to optimize the design of the catalyst component content.
