Effective Fe/K Catalyst for Fischer–Tropsch to Light Alkenes

Construction of Nanoflower Cobalt‐Based Catalyst for Methane‐Free CO Hydrogenation to Hydrocarbon Reaction

“…The activity of a catalyst can usually be compared by the temperature at which it undergoes a half-way conversion (i. e. a conversion rate of 50 %). [27,29,30] As shown in Tables 2 and 3 as well as Supporting Information Figure S3, the CO conversion rate of reference catalyst R1 (i. e., the one without using structure-directing agent) increased from 5.8 % to 95.3 % in the reaction temperature range of 210 °C-260 °C. It can be obtained by curve fitting that the half-way conversion temperature of catalyst R1 is ca.…”

“…The solution to this situation is to compare and study their respective selectivity data based on the same or similar CO conversions. [29,30] There are two forms of oxygen removal routes in the dissociation process of CO molecules, one is oxygen removal completed in the form of H 2 O, and the other is oxygen removal completed in the form of CO 2 . [40] According to the CO hydrogenation mode proposed by Iglesia [40] et al, there are two oxygen removal modes in the dissociation process of CO molecules.…”

“…[20,21] During the catalytic reactions, AlÀ OÀ Zn type supports can generally form AB 2 O 4 spinel structure (i. e., ZnAl 2 O 4 phase). [22][23][24][25][26][27][28][29][30] In this article, we investigated the effect of structure-directing agent urotropine on cobalt-based catalyst supported on AlÀ OÀ Zn type carrier and achieved an initial and pioneering exploration of methanefree CO hydrogenation to hydrocarbon reaction at mild CO conversion range. Coprecipitate solutions A and B at 40 °C, age for 1 h, and thoroughly filter and wash with a Buchner funnel to obtain filter cake LB0.…”
