  intra-particle
When the particles are heterogeneous, not only become the mentioned interactions more complex, but must properly account for the intra-particle interactions as well.
      
The results showed that intra-particle diffusion was the rate limiting step in the ion-exchange process.
      
It is suggested that this latter effect is due to AgCl-mediated intra-particle transport of silver.
      
External mass transport with intra-particle diffusion phenomena governed the rate limiting process, which has been confirmed from the Boyd poor non-linear kinetic plots.
      
The adsorbate species are most probably transported from the bulk of the solution into the solid phase through intra-particle diffusion process.

The kinetics of oxidative dehydrogenation of butene-2 on Mo-Bi-Ce/SiO2 catalyst has been investigated by the flow-recirculation glass reator. In the absence of oxygen, the catalyst was redued by butene-2. The kinetics of oxidative dehydrogenation of butene-2 obeyed the Redox mechanism. The values of parameters of the kinetic equation were estimated by linear least square method. The heats of adsorption of butene-2 and oxygen were determined by the pulse method. The kinetics and intra-particle diffusion...

Studying fine-grained carbonate rocks by ultra-technique can inquire into its vari-ous origin, secondary change in diagenesis and type of pores and evaluate its reservior properties. Analysis by SEM proved that chemogenic carbonate rocks have the equigran-ular and inequigranular texture with various euhedral degree, and the inter-crystaline pores are abundant. The remains of fossil fragment, algae trace or distint sporangia, algae tube, algae ball can be seen under SEM system in biogenic carbonote rocks. Pores in this kind of rocks are mainly inter- particle and intra-particle. The micritic carbonate rocks of mechanical origin have mud-debris structure. Identification of clay minerals in fine-grained carbonote rocks is useful, in deterimning the sedimentary and diagenetic environment.By synthetical study on fine-grained carbonate rocks of various ages in southern and northern China, we can find out the primary and secondary types of pores and its developmental history which is of practical significance in calculate the potential reservoir beds.

The effectiveness factors of extruded catalysts of four different shapes were calculated numerically by finite difference method. The results of calculation show that the three-lobed catalyst is much better than cylindrical-shaped in diffusion behavior. When intra-particle diffusion limitation is important, the use of non-cylindrical catalysts can increase superficial reaction rate markedly. An evaluation inequality about the effect of catalyst shape on the effectiveness factor of catalyst is proposed.
