CAI331 Biochemical and Thermochemical Conversion of Biomass Syllabus:

CAI331 Biochemical and Thermochemical Conversion of Biomass Syllabus – Anna University Regulation 2021

COURSE OBJECTIVES:

 To expose the students with different bio and thermal conversion of biomass.

UNIT I BIOMASS CHARACTERIZATION

Biomass – types – fuels from biomass. Terms and units used in biomass production. Biomass fuel characterization – physical, chemical and thermal – energy release. Supply chain – harvesting / collection – transportation and processing. Briquetting – types – pelletizing.

UNIT II BIOCHEMICAL CONVERSION

Biochemical degradation – factors affecting biogas production – types of biogas plants – construction details – operation and maintenance – utilization of biogas – slurry handling, utilization and enrichment – high rate biomethanation process – landfills – bioethanol – feedstock – process – utilization – composting – methods – machinery.

UNIT III THERMO CHEMICAL CONVERSION BY COMBUSTION

Thermochemical degradation. stoichiometric air requirement – Combustion process – chemistry of combustion – combustion zones – emissions. Cofiring of biomass. Incinerators – layout. Combustion of wastes and MSW. Wood burning stoves – types- operation.

UNIT IV THERMOCHEMICAL CONVERSION BY GASIFICATION AND PYROLYSIS

Biomass gasification – chemistry of gasification – types of gasifier – Gas cleaning & conditioning – utilization of producer gas – emissions – commercial gasifies plants. Pyrolysis – product recovery – types – biochar – bio oil – operation – recovery.

UNIT V COGENERATION AND WASTE HEAT RECOVERY

Cogeneration technologies – cycles – topping – bottoming – problems – applications – selection. Waste heat recovery – plate heat exchangers – waste heat boilers – heat pumps – thermic fluid heaters – selection of waste heat recovery.
