Abstract: An investigation on the formation of an effective activity layer by acetylene penetration in copper-bismuth catalyst with spherical silica gel as supporter was conducted in connection with butynediol synthesis. Employing Weisz-Prater Criterion, it was proved that, within the scope of our experimental conditions, acetylene was the key component in the bicomponent in-trapellet diffusion control system. Since acetylene showed zero order in intrinsic reaction kinetics, according to the criterion value 2A, valuable conclusions were drawn by comparing uniformed distributed copper with egg-shell and multilayer distributed catalyst pellets.

摘要： 本文结合丁炔二醇合成反应探讨了以硅胶为载体的铜铋催化剂在反应时由于乙炔渗入深度形成的有效活性层.采用Weisz和Prater判准,证明在实验条件下乙炔为双组份有内扩散控制时的关键组份.乙炔的本征反应级数为零级,按判准Ψ_A~2值有关因素(C_(甲醛)、温度和乙炔压力),对均匀型催化剂与蛋壳型、多层型催化剂在理论和实验上作比较,并得到有意义的结论.
