“…Pyrolysis occurs in the hot bed and tars produced are cracked by contact with this material, resulting in a product gas with low tar content [52]. In a comparison based on tar, carbon conversion and scale-up potential, circulating fluidised bed technology was observed to be superior to bubbling bed technology [68].…”

“…Fluidised bed gasification has generally been used for biomass gasification at larger scales of operation than fixed bed [59], and is reviewed by Siedlecki et al [68]. A small fraction of feedstock is added to a bed of fine-grained material, most commonly silica sand, which is fluidised by a stream of introduced gasification medium.…”

“…Driers used to achieve this include directly heated rotary driers which utilise energy from the flue gas, or indirectly heated fluidised bed driers which use steam. Commercial biomass gasifiers are reported as running on feedstock with 20%-50% wt moisture [68].…”

Abstract:The use of gas fermentation for the production of low carbon biofuels such as ethanol or butanol from lignocellulosic biomass is an area currently undergoing intensive research and development, with the first commercial units expected to commence operation in the near future. In this process, biomass is first converted into carbon monoxide (CO) and hydrogen (H 2 )-rich synthesis gas (syngas) via gasification, and subsequently fermented to hydrocarbons by acetogenic bacteria. Several studies have been performed over the last few years to optimise both biomass gasification and syngas fermentation with significant progress being reported in both areas. While challenges associated with the scale-up and operation of this novel process remain, this strategy offers numerous advantages compared with established fermentation and purely thermochemical approaches to biofuel production in terms of feedstock flexibility and production cost. In recent times, metabolic engineering and synthetic biology techniques have been applied to gas fermenting organisms, paving the way for gases to be used as the feedstock for the commercial production of increasingly energy dense fuels and more valuable chemicals.

“…Some of the reported advantages of biomass, such as its CO 2 life cycle neutrality [5], its moderate NO x or SO 2 emissions and its autonomy as a resource [6], make it a very useful feedstock for achieving these fixed goals. The energy conversion of biomass can be performed in different ways, bio and thermochemical being the most common.…”

Optimization of a Bubbling Fluidized Bed Plant for Low-Temperature Gasification of Biomass

Investigation into clean energies has been focused on finding an alternative to fossil fuels in order to reduce global warming while at the same time satisfying the world's energy needs. Biomass gasification is seen as a promising thermochemical conversion technology as it allows useful gaseous products to be obtained from low-energy-density solid fuels. Air-steam mixtures are the most commonly used gasification agents. The gasification performances of several biomass samples and their mixtures were compared. One softwood (pine) and one hardwood (chestnut), their torrefied counterparts, and other Spanish-based biomass wastes such as almond shell, olive stone, grape and olive pomaces or cocoa shell were tested, and their behaviors at several different stoichiometric ratios (SR) and steam/air ratios (S/A) were compared. The optimum SR was found to be in the 0.2-0.3 range for S/A = 75/25. At these conditions a syngas stream with 35% of H 2 + CO and a gas yield of 2 L gas/g fuel were obtained, which represents a cold-gas efficiency of almost 50%. The torrefaction process does not significantly affect the quality of the product syngas. Some of the obtained chars were analyzed to assess their use as precursors for catalysts, combustion fuel or for agricultural purposes such as soil amendment.
