前言由于分子筛催化裂化及一些燃烧反应在粒子被提升的同时会完成,所以近十年来快速流化床反应器的研究发展较快,国内有化工治金所的研究报导及山西煤炭化学所用于丁烯氧化脱氢的研究。预料快速流化床在今后会逐步进入一些化学化工领域。描述流化现象的数学模型,对于催化反应可按 Thiele 模数(即等于(d_p/2)((K/D_e)~(1/2)))分为二类。当 Thiele 模数小于1.0时可应用于均相模型和 Thiele 模数大于1.0时可应用的非
Preface Due to the zeolite catalytic cracking and some combustion reactions will be completed while the particles are being lifted, the rapid development of fast-fluidized bed reactors has been rapidly developed in recent ten years. The research reports of the chemical treatment and metallurgy institutes in China and the research reports of the coal chemical industry in Shanxi Study on Oxidative Dehydrogenation of. Rapid fluidized bed is expected in the future will gradually enter a number of chemical and chemical fields. The mathematical model describing the fluidization phenomena can be divided into two categories according to the Thiele modulus (ie equal to (d_p / 2) ((K / D_e) ~ (1/2)) for the catalytic reaction. Can be used when the Thiele modulus is less than 1.0 for homogeneous models and for Thiele modulus greater than 1.0
