一、前方烃类蒸汽转化催化剂的工业制备,一般是在适当的溶液中浸渍多孔裁体,然后煅烧、分解以获得有活性组份的催化剂。众所周知,烃类蒸汽转化反应受内扩散控制,当反应与多孔催化剂内部的传质过程同时进行时,催化剂的内表面不可能被充分利用,因此,内扩散过程对反应速度的影响是不可低估的。为了提高单位体积催化剂的活性,通常把工业
I. Industrial preparation of hydrocarbon steam reforming catalysts in the front is generally by impregnating a porous body in a suitable solution and then calcining and decomposing to obtain a catalyst having an active component. It is well known that the hydrocarbon steam reforming reaction is controlled by internal diffusion. When the reaction is carried out simultaneously with the mass transfer process inside the porous catalyst, the inner surface of the catalyst can not be fully utilized. Therefore, the influence of the internal diffusion process on the reaction rate can not be underestimated . In order to increase the catalyst activity per unit volume, usually put the industry
