Highly Dispersed CoO Embedded on Graphitized Ordered Mesoporous Carbon as an Effective Catalyst for Selective Fischer–Tropsch Synthesis of C5+ Hydrocarbons

Abstract

Herein, we report the high Fischer–Tropsch synthesis performance of the Co-based catalysts supported on graphitized ordered mesoporous carbon (GMC-900) by using a facile strategy. Compared with CMK-3 and active carbon (AC), the obtained GMC-900 by using pollution-free soybean oil as a carbon source exhibited enhanced catalytic performance after loading Co species due to its highly crystallized graphitic structure and uniform dispersion of CoO. As a result, Co/GMC-900 was an effective catalyst with the maximum C5+ selectivity of 52.6%, which much outperformed Co/CMK-3 and Co/AC. This research provides an approach to produce advanced Co-based catalysts with satisfactory performance for efficient Fischer–Tropsch synthesis.

Promotion of Metal–Organic-Framework-Derived Co@C Catalysts for Fischer–Tropsch Reaction by Physical Mixing of Aluminum Isopropoxide

“…The increase in the specific surface area is most likely related to the decrease in the granule size with increased Al loading, as observed from BET measurements and TEM images (Table , column 4). All catalysts show typical type IV N 2 adsorption–desorption isotherms , with clear hysteresis loops (Figure S7 in the Supporting Information), indicating the presence of mesopores in the catalysts. Broadening of the hysteresis loop with increasing Al loading and accompanying pore size distribution curves (Figure S8 in the Supporting Information) indicate that the pore size distribution widens with increasing Al loading, as would be expected from random arrangements of the underlying building blocks.…”
