采用改进的中压反应设备,在以硫化钨镍加于酸性载体上的双重性催化剂上,进行了正己烷异构化动力学的研究。从所得结果建立了描述空间速度、氢压等对转化率影响的动力学关联式: P_(n_0),P_(H_2)为反应器入口正己烷及氢气压力; v_m为正己烷克分子空间速度; x为转化卒;A及B为常数。式中(1/(AP_(H_2)~(0.5))+B与温度的关系符合Arrhenius关系式,其视活化能为26.6千卡。根据所得结果,对正己烷在双重性催化剂上异构化反应机理进行了讨论。
An improved medium pressure reaction equipment was used to study the isomerization kinetics of n-hexane on a dual catalyst with tungsten-nickel sulfide on an acidic support. Based on the results obtained, kinetic equations describing the influence of space velocity and hydrogen pressure on the conversion rate were established: P_ (n_0) and P_ (H_2) are the pressure of n-hexane and hydrogen at the inlet of the reactor; v_m is the n-hexane molecular space velocity; x is the transition; A and B are constant. In the formula, the relationship between (1 / (AP_ (H_2) ~ (0.5)) + B and temperature is in accordance with the Arrhenius equation, and its apparent activation energy is 26.6 kcal.According to the results obtained, n-hexane isomerizes on a dual catalyst The reaction mechanism is discussed.
