Evaluation of biomass potential in Binh Dinh province
Abstract
Vietnam is a developing country and has large biomas potential to produce energy, fuels and chemicals. As an agricultural country, Vietnam has diversified biomass resource from rice crop, corn cob, cassava crop sugarcane bagasse and peanuts crop residues, etc. In this approach, we used Geospatial Toolkit software (GsT) to evaluate and estimate the potential of biomass in each region as well as Binh Dinh province. GsT focused on agricultural biomass residue and was divided into 5 categories: sugarcane crop, peanut crop, cassava crop, rice crop and corn crop residues. The potential of electric power produced from rice crop residues and corn crop residues is 61850.72 and 51892.97 MWh respectively. Design capacity with draw materials of rice crop residues and corn crop residues can be used for power generation is 8.83 and 7.4 MW. In addition, we aslo analysed thermal gravimetric of rice husk, rice straw and corn cob for energy generation. The initial decomposition of biomass in inert environment was noticed between 200÷380 o C. The second decomposition of biomass in inert environment continuously occurred above 400 o C and char from pyrolysis of rice husk and rice straw were higher than of corncob. These results have large significants in production electric, power and chemical from biomass.
