Poisoning of a Silica-Supported Cobalt Catalyst due to Presence of Sulfur Impurities in Syngas during Fischer–Tropsch Synthesis: Effects of Chelating Agent

Industrial & Engineering Chemistry Research, 2014
The effects of sulfur impurities on the performance of cobalt-based Fischer–Tropsch catalysts are evaluated under industrially relevant operating conditions of temperature, pressure, and impurity levels. Chelating agents (CAs) were used to modify the SiO2 support, and the performances of the CA-modified catalysts are compared with conventional Co/SiO2 ...

A Phenomenological Model for Degradation of Solid Oxide Fuel Cell Anodes Due to Impurities in Coal Syngas

ASME 2009 7th International Conference on Fuel Cell Science, Engineering and Technology, 2009
A new phenomenological one-dimensional model is formulated to simulate the typical degradation patterns observed in Solid Oxide Fuel Cell (SOFC) anodes due to coal syngas contaminants such as arsenic (As) and phosphorous (P). The model includes ordinary gas phase diffusion including Knudsen diffusion and surface diffusion within the anode and the ...

A highly integrated ceramic membrane‐based reactor for intensifying the biomass gasification to clean syngas

AIChE Journal
Biomass gasification for syngas production is a key operating unit in the biomass utilization process. However, its overall efficiency and stability are often restricted by the presence of complex impurities, including particulate matters (PMs) and tars.

Oxide-Encapsulated Silver Electrocatalysts for Selective and Stable Syngas Production from Reactive Carbon Capture Solutions.

Angewandte Chemie
Electrolysis of bicarbonate-containing CO2 capture solutions is a promising approach towards achieving low-cost carbon-neutral chemicals production. However, the parasitic bicarbonate-mediated hydrogen evolution reaction (HER) and electrode instability ...

Thermodynamic equilibrium modeling of gasification for syngas production from carbonaceous feed containing the sulfur impurity

International Journal of Chemical Reactor Engineering
Abstract The present study deals with modeling and simulating the gasification process for syngas production. Equilibrium modeling was done to study the product gas composition by changing the process parameters, viz., reaction temperature, equivalence ratio, and moisture content.

Temperature and Impurity Concentration Effects on Degradation of Nickel/Yttria‐stabilised Zirconia Anode in PH₃‐Containing Coal Syngas

Fuel Cells, 2010
AbstractDegradation of the Ni/yttria‐stabilised zirconia (YSZ) anode of the solid oxide fuel cell has been evaluated in the coal syngas containing different PH3 concentrations in the temperature range from 750 to 900 °C. Thermodynamic equilibrium calculations show that PH3 in the coal syngas gas is converted mostly to P2O3 at 750–900 °C.

Study on the catalytic performance of ZnCrAl co-precipitated oxides washed with ammonium carbonate solution in the synthesis of light olefins from syngas

New Journal of Chemistry
Ammonium carbonate solution was used instead of water to wash the impurities in the coprecipitation method, and oxides with increased oxygen vacancy content and catalytic effect were obtained.
