Pollutants from Energy Sources

Abstract

Waste disposal is a major problem in most of the countries. Thus, waste to energy conversion will fulfill the future energy demand as well as resolve the pollution issues. This work mainly involved in the extensive study on pyrolysis and gasification of biomass and hazardous e-waste into useful energy and its impact on the environment. Microwave-assisted pyrolysis (MAP) technique has attracted the research society because of its energy efficient process and more viable route for converting the waste into potential products. Similarly, this chapter provides the assessment of biomass and e-waste volarization route to produce syngas using different gasification strategies. In addition, this study focused on the pyrolysis and gasification parameters like temperature, equivalence ratio, and particle size, which influence the product yield and emission formation. In general, pyrolysis and gasification of biomass and e-waste produce the volatile products, and it leaves the solid residue like char and ash. As an implementation, this study explained the conversion of waste residue from pyrolysis and gasification into useful products like activated carbon, silicon carbide, and zeolite, which can be used as the catalyst in microwave process and some other applications. At the end, the study covers the utilization of pyrolysis fuel and syngas in compression ignition engines with advanced technologies like CRDI and dual fuel strategies. CRDI and dual fuel mode combustion are the appropriate methods to reduce the engine emissions and enhance the engine efficiency.
