“…Current state of the art examples are almost ubiquitously based on high temperature, pressurized, entrained flow gasifiers with high throughput and fuel flexibility. 1 To determine which gasification technology is best suited to a particular feedstock, and to facilitate design, development and optimisation of the process, coal-specific data under industrially relevant conditions are required. Low rank coals, such as the Victorian brown coals from Australia and the Rhenish lignites from Germany, are attractive potential fuel options for coal to products applications via gasification due to their low cost and relative abundance.…”

The low rank coals from Victoria, Australia, and Rhineland, Germany are of interest for use in entrained flow gasification applications. Therefore, a high temperature, electrically heated, entrained flow apparatus has been designed to address the shortage of fundamental data. A Victorian brown coal and a Rhenish lignite were subjected to rapid, entrained flow pyrolysis between 1100 and 14008C to generate high surface area chars, which were subsequently gasified at the same temperatures under CO 2 in N 2 between 10 and 80 vol %. The Victorian coal was more reactive than the Rhenish coal, and peak char reactivity was observed at 12008C. Char conversion and syngas yield increased with increasing temperature and plateaued at high CO 2 concentration. Ammonia and tar species were negligible and HCN and H 2 S were present in parts per million (volume) concentrations in the cooled, filtered syngas.

“…Thus, the value of V m can be determined according to the slope and intercept of the fitting curve. Then, a plot of ln(V/V m ) versus ln(ln(P/P 0 )) fitting by using least-square method will show a linear trend (Figures 9b and 10b) as well, and the slope of the fitting line is equal to A, which can be used for calculating the value of the surface fractal dimension according to Equation (3). The surface fractal dimension of the fresh 5Fe5Ce/ZSM-5 is 2.61, and it considerably increases to 2.96 after the sulfidation reaction, which indicates a more sophisticated pore distribution for the spent 5Fe5Ce/ZSM-5, and the higher value suggests that the surfaces of the spent 5Fe5Ce/ZSM-5 is more irregular [39].…”

Fe 2 O 3 /ZSM-5 modified with Ce via citrate route (sol-gel approach) is applied for H 2 S removal in 500-700 • C temperature range. The sulfidation activity of Fe 2 O 3 /ZSM-5 is appreciably promoted by introduction of Ce plausibly attributed to the synergy of Fe 2 O 3 and CeO 2 . 5Fe5Ce/ZSM-5 performs the optimal desulfurization behavior at 600 • C with sulfur capacity of 1020 µmol S/g, and the sulfidation process conforms to non-catalytic gas-solid redox reaction mechanism, which yields FeS 2 , Ce 2 S 3 , and S. Fractal analysis is introduced to evaluate the surface porous structure and the adsorption capacity of the sorbent. Its surface fractal dimension is estimated by using Frenkel-Halsey-Hill (FHH) model. It considerably increases after sulfidation plausibly attributed to the formation of a few heterogeneous sulfides or elemental sulfur, which block or cover the surface pore structures of sorbents.

“…In addition, cheaper and more stable price of coal also supports synthetic natural gas as an attractive option to fulfill the need for clean energy from coal. (Kopyscinski et al, 2010) "Synthetic natural gas" or "substitute natural gas" (SNG) is an artificially produced version of natural gas mainly from coal, and also from biomass, petroleum coke, or solid waste (Higman & Tam, 2013). The carbon-containing mass can be gasified, then the resulting syngas can then be converted to methane, the major component of natural gas.…”

As the most abundant and widely distributed fossil fuel, coal has become a key component of energy sources in worldwide. However, air pollutants from coal power plants contribute carbon dioxide emissions. Therefore, understanding how to taking care coal in industrial point of view is important. This paper focused on the feasibility study, including process design and simulation, of a coal to SNG power plant in Kalimantan in order to fulfill its electricity demand. In 2019, it is estimated that Kalimantan will need 2446 MW of electricity and it reaches 2518 MW in 2024. This study allows a thorough evaluation both in technology and commercial point of view. The data for the model is gathered through literature survey from government institution reports and academic papers. Aspen HYSYS is used for modelling the power plant consists of two blocks which are SNG production block and power block. The economic evaluation is vary depends on the pay-back period, capital and operational cost which are coal price, and electricity cost. The results of this study can be used as support tool for energy development plan as well as policy-making in Indonesia.
