A new organic-inorganic hybrid nanocomposite (TBA-Si 2 W 18 Mn 4 @SAB) was synthesized by supporting quaternary ammonium salt of sandwich-type polyoxometalate (TBA-Si 2 W 18 Mn 4 ) on sodium-activated bentonite (SAB) for catalysing an oxidative desulfurization (ODS) process. The synthesized materials were characterized by means of elemental analysis, 29 Si NMR, Fourier transform infrared and UV-visible spectroscopies, X-ray diffraction and scanning electron microscopy. The proposed ODS process was successfully developed on the basis of the catalytic oxidation of organosulfur compounds using TBA-Si 2 W 18 Mn 4 @SAB as catalyst and CH 3 COOH/H 2 O 2 as oxidizing agent.The removal of the sulfur content of gasoline reached 97% at a temperature of 35°C after 1 h using 0.10 g of the prepared catalyst. Various experiments were conducted to investigate the effects of reaction time, catalyst amount, reaction temperature and catalyst type on sulfur removal efficiency. The heterogeneous TBA-Si 2 W 18 Mn 4 @SAB catalyst was found to be reusable for five times. The obtained data illustrated that the use of the TBA-Si 2 W 18 Mn 4 @SAB/ CH 3 COOH/H 2 O 2 oxidation system could be a convenient strategy for reducing the sulfur content of gasoline fuel under moderate reaction conditions.

Catalytic Conversion of Coal and Biomass Volatiles: A Review

et al. 2020

This paper presents a review of recent research on direct upgrading of coal/biomass volatiles into aromatics by catalytic pyrolysis and syngas by gasification with catalytic steam reforming. Coal/biomass valorization is considered an important part to fill up the depletion of modern fossil fuel resources. The catalytic pyrolysis process is a potential approach to improve coal tar/bio-oil quality by minimizing its undesirable properties (high viscosity, corrosivity, instability, etc.) and producing renewable fuels and high-value chemicals, such as aromatics (benzene, toluene, ethylbenzene, xylenes, etc.). Gasification reforming as a promising process for renewable energy utilization can produce H2-rich syngas. The produced syngas can be further synthesized to fuel and chemicals via Fischer–Tropsch synthesis. Thus, this study provides a comprehensive review of the research and development of conversion of coal and biomass volatiles in terms of technological types and catalysts. Aspects related to upgrading technology, the reactor type of catalytic pyrolysis and gasification, and the reaction mechanisms to specific products during the catalytic process are also discussed comprehensively. In particular, catalytic upgrading by fast pyrolysis involves a series of reactions, including deoxygenation, cracking, hydrocarbon pool mechanism, aromatization, and condensation, as well as desulfurization and denitrification in the gasification process. Some key points that are to be addressed for the established process of coal and biomass volatile upgrading may include finding multifunctional catalysts and reactor development for improving the efficiency. Expanding and enhancing knowledge about catalyst utilization and fundamental reaction mechanisms in the thermochemical catalytic conversion technologies of coal and biomass will play an important role in the generation of chemicals and carbon-neutral fuels.

“…The authors have suggested that the changes in the catalytic properties induced by second metal addition to Ni may be caused by changes in the electronic and/or geometric properties of the homogeneous bimetallic particles. Because of this behavior, various bi‐metallic Ni‐based catalysts were also investigated for WGS reaction especially at high temperature and low steam conditions ,,,. Among all, Cu and Fe are two most commonly added secondary metals to Ni‐based catalysts for WGS reaction and methane suppression, because Cu and Fe alone are promising WGS catalysts at low and high temperatures, respectively with negligible methane formation.…”

This article provides a critical review of Ni-based catalysts employed in high temperature and ultra-high temperature water gas shift reaction (WGS) for hydrogen production and methane suppression. The promotional role of nature and type of active metal and support for WGS reaction is discussed with respect to activity and selectivity. This review mainly covers the recent strategic catalytic formulations like promotion with alkali metals, alloying with another metal and core@-shell-like structures for suppressing methanation during WGS reaction. The change in nature and strength of CO adsorption over modified Ni-surfaces is discussed using available in situ CO-DRIFTS results. The various WGS reaction and CO methanation pathways are also presented together with insights gained from computational DFT studies.[a] Dr.
