The document outlines three main energy conversion technologies for producing energy from biomass: combustion, gasification, and pyrolysis. Combustion is the most common method for generating heat and electricity, while gasification converts biomass into gas at high temperatures, and pyrolysis produces bio-oil through thermal decomposition in the absence of oxygen. Additionally, it distinguishes between biofuels made directly from plant matter and fossil fuels formed from the decomposition of organic matter over time.

6. we used to produce energy from biomass
are three main categories:
energy conversion technologies-
o Combustion
o Gasification
o Pyrolysis

7. Primary energy conversion technologies
 Combustion - direct combustion of biomass is the most common way of
converting biomass to energy - both heat and electricity. Compared to the gasification
and pyrolysis it is the simplest and most developed.
 Gasification - gasification is a high-temperature (1200-1400 Degree Celsius)thermo
chemical conversion process but the process is used for production of gas, instead of
heat.
 Pyrolysis - thermal decomposition occurring in the absence of oxygen. We use
pyrolysis to produce a liquid fuel, bio-oil or pyrolysis oil.

14. Biofuel Fossil fuel
Bio-fuel is produced directly
from plant matter typically corn,
sugar cane, sugar beets, or
cellulose transforming it into
alcohol.
Fossil fuels are produced by
either the decomposition of
plant or animal matter over long
periods of time under certain
conditions such as high
temperature and pressure.
Fossil fuels are coal, oil, and
natural gas.
