Development of fluidized bed gasifier for sustainable energy production in rural areas
The economic viability and achievement of high efficiency in biomass gasification applications depends on the gas quality and gasification parameters. High LHVgas and purity enables the biomass producer gas for further exploitation in Internal Combustion Engines (ICES). Small scale mobile power production units are of great importance towards a sustainable energy world and especially for the renewable energy. Versatile and modular energy production units would enable ‘green’ energy production and operation close to the place of feedstock origin, either on mountainous or island regions minimizing transportation and logistics costs of fuels 1; thus agricultural residues generate in diverse topography regions like Mediterranean could comprise an attractive alternative solid biofuel for clean energy production. Especially gasification is a promising step towards H2 production from biomass 2. The solid biomass can be converted, via gasification, to an easier to handle gaseous fuel that could be further exploited for renewable hydrogen and/or energy production. Gasification process is considered as a two stage thermochemical valorization method consisting, at primary stage, by pyrolysis that takes place in the absence of an oxidizing medium. 3. When considering to the development of commercial scale gasifiers the study of biomass gasification aiming at the selection of information for the design, construction and preliminary operation of pyrolysis and gasification in laboratory scale reactors is of primary importance. Successively, in order to select the proper agricultural residue for performing the gasification experiments either in laboratory or pilot scale, a thorough bibliographic study takes place and concerns the availability and physicochemical characteristics of agricultural residues. Olive kernel seems to be the proper agro residue for gasification in pilot scale in Mediterranean countries due to its established logistics, absence of competition with food industry and its suitable physicochemical properties for exploitation through gasification.
