Co-gasification Characteristics of Biomass and Bangladeshi Bituminous Coal under Entrained Flow Conditions

The main limitations for the coal-based power/chemical production using conventional techniques are lower thermal efficiency and higher greenhouse gas emission. However, the advanced gasification technique is an efficient pathway for the synthesis of valuable fuels and chemicals. This research is the first-ever investigation on the co-gasification characteristics of renewable pine bark biomass and Bangladeshi Barapukurian coal. The results show that considering the heating value and other performance parameters, 50% of coal can be replaced efficiently with pine bark biomass using the co-gasification technique. Also, about 50% steam (energy-intensive) can be replaced with low-cost CO2 reactant under co-reactant condition.
