,e-Business — electronic business and PLM,umn with a fixed bed of catalyst particles through which liquid flows in the form of films, droplets and rivulets. Gas moves cocurrently; sometimes counter-current flows are also used. Usually one reactant is introduced in the liquid phase and the other in the gas phase.尊重 发表于 2025-3-27 04:49:26
Antti Saaksvuori,Anselmi Immonenroductivity, lowering the process selectivity and reducing the life of the catalyst. Among these include the oxidation of ethylene, benzene, C. hydrocarbons and methanol, the ammoxidation of propylene, methanol synthesis (Lurgi), the hydrochlorination of methanol and steam reforming of natural gas and naphtha.手势 发表于 2025-3-27 05:50:53
Preparing for the PLM strategy,restrictions against mass and heat transfer in the interior and in the gas film surrounding the particle, and it accepts a general type reaction rate expression such as a power law expression or a Langmuir-Hinshelwood expression. The model is reduced to a number of coupled second order differentialangina-pectoris 发表于 2025-3-27 11:45:58

Preparing for the PLM strategy, for many catalytic and noncatalytic reactions involving solid particles and a gas or liquid. However, gas fluidized bed reactors present a challenge to the engineer because their patterns of gas-solid contacting and mixing are complex and difficult to characterize. Contacting and mixing are intimat得体 发表于 2025-3-28 02:34:28

Understanding the product lifecycle,, Baker and Muroyama and Fan . Epstein distinguished in particular the difference between three-phase fluidized beds and slurry reactors. In slurry reactors the size of the solid particles is normally smaller than 0.1 mm while in three-phase fluidization the particle diameter is bigger
