The temperature range was 573653 K with butane concentrations up to 3 mol % in the feed, which is within flammability limits but below ignition temperatures. The rate data were modeled using power low kiics with product inhibition and included total oxidation and deposition reactions. Kiic parameters were estimated using a multiresponse, nonlinear regression algorithm showing intercorrelation effects. The kiics were bined with independent measurements of catalyst diffusivity and reactor heat transfer using a onedimensional heterogeneous reactor model. Model predictions and observed temperatures and concentrations from nonisothermal pilot plants pared up to 115 days on stream. Agreement was acceptable with inlet butane concentrations up to mol %. For example, runaway was predicted at a temperature 3 K higher than observed. Effectiveness factors around the hot spot were estimated at with catalyst surface temperature 23 K higher than average gas temperature. 摘要 _報(bào)道－指示性摘要 對(duì)文獻(xiàn)中的基本內(nèi)容作較為詳盡的報(bào)道性介紹，對(duì)其它部分則作指示性的表述。 以最短的篇幅傳遞最大信息量。 摘要 _報(bào)道－指示性摘要 Baffle effects on the performance of a catalytic fluidized bed reactor were examined experimentally. The circulating fluidized bed reactor or riser was 102 mm in diameter and m in height. Reaction was the catalytic deposition of ozone using FCC particles with a mean diameter of 89 um, impregnated with ferric oxide as catalyst. Four ringtype baffles, mounted horizontally around the riser wall, were used in this study. Ozone concentrations were measured in both axial and radial directions under various operating conditions in a riser with baffles, the ozone concentration in the radial direction was more uniform and the ozone conversion was higher than that in a riser without baffles except at the lowest gas velocity used. A mathematical model developed accounted for the gasphase ozone conversion under various operating conditions. The gassolid contact efficiency in the riser was discussed in light of the model. 摘要 _論著摘要 論著摘要包括期刊論文、會(huì)議論文、技術(shù)報(bào)告、學(xué)位論文、專著等的摘要，內(nèi)容通常有四個(gè)方面： 研究的目的和范圍 研究的方法 研究的結(jié)果 作者對(duì)研究的主要結(jié)論 摘要 _論著摘要 A major difficulty affecting the control of product quality in industrial polymerization reactors is the lack of suitable online polymer property measurements.
