A pseudohomogeneous axial dispersion model accounting for both bulk-fluid-phase dispersion and intraparticle diffusion is solved to examine the effect of widely disparate configuration diffusion coefficients on selectivity in the reactor. The operator formalism is shown to obtain also solutions for the mathematically more complicated situation of a wall-catalyzed reactor with a nonuniform, fully developed flow profile. Computations presented for the axial dispersion model demonstrate that intraparticle diffusion hindrances in molecular sieve catalysts can drastically affect the selectivity of the xylene isomerization system. The influence of reactor parameters (Peclet and Damkohler numbers) and reactor feed conditions on product selectivity is investigated in order to elucidate the conditions under which optimum selectivity can be expected.","PeriodicalId":13548,"journal":{"name":"Industrial & Engineering Chemistry Fundamentals","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1986-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77535073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the absence of H/sub 2/S the pyrolysis rates and product selectivities remained virtually constant over large changes in S/V ratio. At low S/V ratios H/sub 2/S can either inhibit or accelerate the rate of hydrocarbon decomposition depending upon the nature of the intermediate radicals. Under high S/V conditions, H/sub 2/S caused an increase in pyrolysis rate for all hydrocarbons tested. The results are consistent with a mechanism and kinetic analysis in which the effect of high surface area is to catalyze the decomposition of H/sub 2/S into intermediate radicals. The effects of H/sub 2/S on product selectivity appear as a large increase in propylene yield from n-butane feed, increased isobutene from isobutane feed, and little or no change in selectivity with n-decane, propane, or ethane feed.","PeriodicalId":13548,"journal":{"name":"Industrial & Engineering Chemistry Fundamentals","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1986-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78826897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
