摘要

摘要比较研究了铁基纳米分散体在两种不同浆式反应器（即连续搅拌罐反应器（CSTR）和浆式气泡塔反应器（SBCR））中进行费托合成的催化性能。研究发现，在相同的工艺温度下，使用四个等间距 1 毫米孔的气体分散器的 SBCR 中的 CO 转化率低于 CSTR 中的转化率。然而，这一观察结果与文献中的其他报告并不一致。用一个中心开有 2 毫米孔的板代替气体分散器后，CO 转化率提高到接近 CSTR 中的数值。计算了不同类型反应器的反应速率常数。

Behavior of Nanocatalysts in Fischer–Tropsch Synthesis in Various Types of Three-Phase Slurry Reactors

The catalytic performance of iron-based nanodispersions in Fischer–Tropsch synthesis in two different slurry reactor types, specifically a continuous stirred-tank reactor (CSTR) and a slurry bubble column reactor (SBCR), was comparatively investigated. It was found that, at equal process temperatures, the CO conversion in the SBCR using a gas disperser with four equally spaced 1-mm holes was lower than that in the CSTR. However, this observation is inconsistent with other reports in the literature. Replacing this disperser with a plate with a single centered 2-mm hole enhanced the CO conversion up to values close to those obtained in the CSTR. The reaction rate constants were calculated for the different reactor types.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
