An exergy based approach to determine production cost and CO2 allocation for petroleum derived fuels

The renewable and non-renewable exergy and CO2 costs of petroleum derived fuels produced in Brazil are evaluated using exergoeconomy to rationally distribute the exergy costs and the CO2 emitted in processes with more than one product. An iterative procedu ...

Sulfur containing organic compounds in the raw producer gas of wood and grass gasification

Christian Ludwig, Tilman J. Schildhauer

The detailed description of gas streams in biomass gasification plants is necessary for the correct design and operation of these units. Sulfur containing compounds are usually present in biomass gasification gas, since sulfur is typically found in the fee ...

An assessment of different solvent-based capture technologies within an IGCC–CCS power plant

François Maréchal, Laurence Tock, Jeremy Urech

This study evaluates three different solvent absorption processes for the pre-combustion capture of CO2 for a black coal IGCC (Integrated Gasification Combined Cycle) power-plant, with the aim of determining the best solvent process for pre-combustion capt ...

Thermo-economic and environmental model of microalgae-to-SNG conversion process through hydrothermal gasification

François Maréchal, Adriano Viana Ensinas, Alberto Mian, Kevin Arrandel

Due to its high photosynthesis conversion efficiency, microalgae are currently considered as a serious feedstock for next-generation biofuels production. One possible conversion process is the production of synthetic natural gas (SNG) through catalytic hyd ...

Gasification of Hay in a Bench Scale Fluidised Bed Reactor with Emphasis on the Suitability for Gas Turbines

Christian Ludwig, Marco Wellinger

Thermal gasification of pasture plants (hay) is so far considered as difficult mainly due to the high amount of inorganics (ash, alkalis). Under certain circumstances it could be an additional resource for power production. There has been some experiments ...

Catalysts for High Temperature Gas Cleaning in the Production of Synthetic Natural Gas from Biomass

Bio synthetic natural gas (Bio-SNG) is being proposed as an alternative to the natural gas of fossil origin (NG) [1]. Bio-SNG consists mainly of CH4 (at least 95%mol), has a high heating value (e.g. 10 kWh/m3N), and respects the quality standards of the NG ...

Increasing Conversion Efficiency in Fuel Ethanol Production from Lignocellulosic Biomass by Polygeneration - and a Paradoxon between Energy and Exergy in Process Integration

François Maréchal, Martin Gassner

In the public and scientific debate on biofuels, ethanol from lignocellulosic biomass is generally the most popular alternative that may allow for a sustainable production. Compared to thermochemical processing of biomass which assures a complete conversio ...

Thermo-economic modeling of fuel decarbonization processes

François Maréchal, Laurence Tock

A systematic framework is developed for the thermo-environomic modeling, analysis and optimization of fuel decarbonization processes using precombustion routes to decarbonize the fuel by CO2 removal before burning the purified H2-rich gas in a gas turbine ...

Adsorption and strain: The CO2-induced swelling of coal

Brice Tanguy Alphonse Lecampion

Enhanced coal bed methane recovery (ECBM) consists in injecting carbon dioxide in coal bed methane reservoirs in order to facilitate the recovery of the methane. The injected carbon dioxide gets adsorbed at the surface of the coal pores, which causes the c ...
