Biomass gasification technology: The state of the art overview

In the last decades the interest in the biomass gasification process has increased due to the growing attention to the use of sustainable energy. Biomass is a renewable energy source and represents a valid alternative to fossil fuels. Gasification is the thermochemical conversion of an organic material into a valuable gaseous product, called syngas, and a solid product, called char. The biomass gasification represents an efficient process for the production of power and heat and the production of hydrogen and second-generation biofuels. This paper deals with the state of the art biomass gasification technologies, evaluating advantages and disadvantages, the potential use of the syngas and the application of the biomass gasification. Syngas cleaning though fundamental to evaluate any gasification technology is not included in this paper since; in the authors’ opinion, a dedicated review is necessary.

Nowadays renewable energy sources are an essential issue in the framework of global energetic scenario. Biomass can represent an effective substitute to conventional fuels and a sustainable, carbon-neutral and environmental-friendly energy resource. Biomass gasification is a promising technique in order to valorize biomass conversion in energy, biofuels and chemicals.Figure optionsDownload as PowerPoint slide
