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.
Highlights
With the rapid development of human society and economy, it becomes more and more difficult for crude oils to meet people’s demands (Guo et al, 2016; Hao et al, 2016; Zhang et al, 2017)
SBA-15 was synthesized in an acidic environment with ethyl silicate as the silicate source and P123 as the soft template
The ratio of relative integrated intensity (ID/IG) between these two bands implies the degree of graphitization and the disorder degree of functionalized groups and defects, which was calculated to be 1.98, 1.55, and 2.65 for Co/CMK-3, Co/GMC-900, and Co/active carbon (AC), respectively. These results indicate that GMC-900 has a high degree of graphitization than Co/CMK-3 and Co/AC, which are in accordance with the above X-ray diffraction (XRD) results
Summary
With the rapid development of human society and economy, it becomes more and more difficult for crude oils to meet people’s demands (Guo et al, 2016; Hao et al, 2016; Zhang et al, 2017). Carbon materials are considered as some of the most desirable supports in FTS owing to their unique specific structure and chemistry, such as surface inertness, controllable crystallized graphitic structure, high conductivity, and acid or alkali resistance (Lyu et al, 2019; Dlamini et al, 2020). We report the high Fisher-Tropsch synthesis performance of the Co catalysts supported on graphitized ordered mesoporous carbon (GMC-900) by using pollution-free soybean oil as a carbon source. We chose the porous CMK-3 prepared and commercial AC from other carbon sources as the supports and controls to evaluate the catalytic performance of GMC-900 in FTS. Unreacted gases (H2, N2, and CO) and by-products (CH4 and CO2), and hydrocarbons (C1–C30) can be detected by TCD and flame ionization detector, respectively
