Biomass-derived fuels can contribute to energy sustainability through diversifying energy supply and mitigating carbon emissions. However, the biomass chemistry poses an important challenge, i.e., the effective hydrogen to carbon ratio is significantly lower for biomass compared to petroleum,...

The techno-economic assessment of biomass pyrolysis gasification system for central gas supply was conducted using cost and profit method. From the results, it can be seen that Net Present Value (at discount rate of 10%), profit/Cost, and Internal Return Rate of financial analysis in village...

Thermochemical biorefinery based on dimethyl ether (DME) as an intermediate is studied. DME is converted into methyl acetate, which can either be hydrogenated to ethanol or sold as a co-product. Considering this option together with a variety of technologies for syngas upgrading, 12 different...

Nowadays, the global warming is considered as a world problem because it influences the environment by increasing the average temperature of earth surface. One of the greenhouse gases that release from human activities and fossil fuels combustion in industry is CO2. Several technologies are...

The performance differences between the fluidized-bed and the fixed-bed operation modes were comparatively studied in a pressurized coal-fuelled chemical looping combustion (CLC) process. Pressurized thermogravimetric (TG) analysis was applied to elucidate the findings observed in pressurized...

Driven by the search for high efficiency power generation with low CO2 emissions, several works in the last years investigated the integration of gas turbine cycles and high temperature fuel cells to arrange power plants with CO2 capture.

This paper presents a power plant concept based on an oxy-fired circulating fluidized bed combustor (oxy-CFBC) combined with thermal energy storage on a large scale. The concept exploits to full advantage the large circulation flows of high temperature solids that are characteristic of these...

In this paper, we experimentally investigated the time evolution of compositions in the gas phase and the hydrate slurry during long-term operations of hydrate-based CO2 separation. We performed continuous gas separation experiments at pressure of 2.3MPa and temperature of 273.2K. We continually...

The iron-based Coal-Direct Chemical Looping (CDCL) combustion process is an alternative to conventional oxy-combustion technologies, where the oxygen used for fuel conversion in the CDCL process is provided by an iron-oxide based oxygen carrier instead of an air separation unit. The iron oxide...
