本文报道了高强度A110-5Q型氨合成球形催化剂的各种密度、抗压强度、比表面、孔结构、催化活性、动力学参数以及穆斯堡尔谱对物相的研究等.结果表明高强度球形催化剂的氧化态结构紧密,孔隙细小,堆密度和颗粒密度提高10—12%.还原态平均孔半径和最可几孔径增大,出现三个微孔体系,比表面仍在9m~2/g以上.实现了抗压强度提高约一倍、保持了高活性低阻力等优良性能.动力学参数指前因子K.和活化能E均有增大,K_o和E遵从补偿效应关系.K_o增大两个数量级与孔结构变化有关.
In this paper, various density, compressive strength, specific surface, pore structure, catalytic activity, kinetic parameters and MUSBORO spectra of high-strength A110-5Q spherical catalysts were reported. The results showed that high The strength of the spherical catalyst is closely related to the oxidation state and the pores are small, the bulk density and the particle density increase by 10-12%, the average pore radius and the most probable pore size of the reduced state increase, and three microporous systems appear and the specific surface is still 9m ~ 2 / g or more.Improve the compressive strength of about doubled to maintain the high activity of low resistance and other excellent performance.Kinetic parameters of pre-factor K and activation energy E have increased, K_o and E follow the compensation effect.K_o Increase by two orders of magnitude is related to the change of pore structure.
