Point process mesoscale model

In this chapter, the multiscale analysis of FTS process is illustrated, and the effects of every scale are discussed on the product distribution of FTS reaction. Flowever, constraint will be exploded in mesoscales viewpoint because there are many combined factors to influence FTS reaction, such as complex reaction mechanism, mass transfer of reactants and products, and flow type of reactor. Therefore, the ASF distribution is always improper in the FTS system. On the other hand, the flow model of the reactor has been investigated, but how the reactor influence the reaction performance of catalyst is still not clear. Therefore, if we want to know the product distribution of different reactors, a lot of experiment should be taken place. Based on these points, the mesoscale phenomena and effects for products of FTS reaction should be investigated in detail. 

The mesoscale effects on the product distribution of FTS should include two points as follow (1) the modified ASF product distribution and olefin readsorption mechanism model and (2) diffusion-reaction model and external-internal diffusion model of FTS process.
