Biomass gasification in fluidized beds: A review of biomass moisture content and operating pressure effects

摘要: Abstract The global dependence on fossil reserves as well the environmental aspects related to them are some of factors that propel research renewable energy forms. Gasification, a thermochemical process converts carbonaceous resources into syngas, is an advantageous alternative due its relatively low costs, high efficiencies, and syngas’ wide variety applications. Although gasification very promising heat, power, fuel production technique, there still field improvement in fluidized beds when it comes operation under pressure with feedstocks containing moderate or moisture contents. Thus, provide enough information address such questions, present work aims at bringing overview concepts, in-depth discussion based simulation, laboratory- demonstration-scale works effects biomass water content different parameters several bed gasifiers. Moreover, diverse strategies for handling high-moisture materials presented, achievements technical difficulties encountered by worldwide development demonstration plant projects designed used pressurized fluidized-bed
