摘要:

目前费托合成常用的固定床、浆态床和流化床三种反应器存在不同程度的传质和传热问题,同时反应物/产物与催化剂难以分离,而微反应器因其可在接近等温和很小压降条件下进行反应,从而有望改善费托合成的反应性能,提高所用催化剂的活性和选择性。本文首先介绍了微反应器的结构和特性,然后从催化剂种类及其在微反应器中颗粒装填式和器壁涂覆式两种形式简述了微反应器中费托合成的实验研究,并从计算流体力学和动力学研究等方面简述了微反应器中费托合成的模拟计算。

Abstract:

At present, the three commonly used fixed bed, slurry bed and fluidized bed reactors for Fischer-Tropsch synthesis have different degrees of mass and heat transfer problems. At the same time, the reactants/products and the catalysts are difficult to separate. The reaction is carried out under conditions close to isothermal and very small pressure drop in the microreactor, which is expected to improve the reaction performance of Fischer-Tropsch synthesis and increase the activity and selectivity of the catalyst used. This article first introduces the structure and characteristics of the microreactor, and then briefly describes the experimental research of the Fischer-Tropsch synthesis in the microreactor from the type of catalyst and its particle loading type and wall coating type in the microreactor. The simulation calculation of Fischer-Tropsch synthesis in microreactors is briefly described from computational fluid dynamics and kinetics research.

Key words: microreactor, Fischer-Tropsch synthesis, catalyst, computational fluid dynamics, reaction kinetics
