ABSTRACT

With rapidly increasing energy costs, the necessity of finding new sources of energy is becoming more urgent than before. As energy sources are limited, this project may be considered as a promising option. The hay of catkin is taken as a potential resource for the project work on fixed bed pyrolysis.

In this research study, the feedstock(biomass) is taken into the fixed bed reactor of stainless steel of 7.62cm diameter and 30 cm length and is heated to 350 ^OC-550 ^OC. This high temperature converts the feedstock into gaseous vapor and solid char. Liquefied petroleum gas (LPG) is flown through the reactor from a cylinder at a controlled rate dispose of the gaseous vapor to collector through a condenser. The condenser helps the vapor to be converted into liquid product. The liquid product is collected and the non-condensable gas is flared of.

ABSTRACT

Biomass gasification is quite new in Bangladesh and may be considered as a promising technology for the useful conversion of waste biomass. The fuel gas produced by gasification can run engines and thus generate electricity. In the present work, literature survey is performed to compare the available proven gasification technologies around the globe in terms of biomass quality and quantity, system complexities and capacity, and economic factors. The outcome of this study would identify a suitable gasification technology for Bangladesh. To explore the full potentials of biomass gasification, necessary data on biomass availability and quality is discussed. A case study is incorporated which applies biomass gasification technology in Bangladesh, to generate power from rice husk. This will provide a practical impression on the successful use of this technology in this country. Finally useful conclusions and possible recommendations are made in favor of adopting this technology in Bangladesh’s perspective.
