Mathematical modeling of catalytic reaction was performed for hollow cylindrical pellets with infinitely long or finite length. For isothermal irreversible first order reaction, intra-particle concentration could be predicted from analytical solutions obtained by solving reaction-diffusion equations. Both diffusional and surface film resistance were considered in the Factors affecting distribut...

Research has been carried out on the preparation of active natural zeolite impregnated with nickel followed by activity testing through hydrocracking catalytic reaction n-Hexadecane. Active was obtained from PT Prima Zeolita Yogyakarta. The concentration in sample ion exchange method [Ni(NH3)6]2+ precursor solution a 0.06M. content catalyst determined Atomic Absorption Spectrophotometer (AAS). ...
