1. Characterization and optimization of the biomass.
2. Physical pre-treatment (size reduction) of biomass.
3. Study of biogas production rate by the biomass mixed with cattle dung at
different temperatures from 35°C to 55°C at a interval of 10°C.

production rate at 35°C is
higher as compared to that at
45°C.
Kinetic rate constant at 55°C
is the highest indicating
highest biogas production
rate, followed by 35°C and
45°C for both the biomasses.

Characterization of lignocellulosic biomass for biogas
production
Aim – Characterization of locally available biomass was performed to know
its potential for biogas production.
Dipti Yadav

Fuel characteristics play a
determining role in the
use of a given feedstock
for biogas production. So,
its necessary that different
properties of a biomass
are known in order to pre-
estimate its value and
suitability as a feedstock.
The volatile solid content destruction are the crucial parameters deciding
the amount of biogas generated from substrate. Bamboo dust shows
highest volatile content.
Results – Proximate analysis of lignocellulosic biomass
Methadology
Physical and chemical
properties of Biomass has
been characterized by
analytical methods like
Proximate analysis
ultimate analysis, fibre
analysis, COD, FTIR,
TGA.

1.Fabricating Solar Flat plate collector
2. Proposed Design of Biogas Digester
3. Heat Exchanger Design- 3.1. Modeling
Dimension of the digester : Based

Diameter - 1.36m
Height - 1.02 m
Insulation thickness- 10mm
Wall thickness- 6mm
Conclusion: The heat transfer characteristic of
75mm coil pitch are much better compared to 50mm
and 25mm at higher dean number with limitation in
space and more pressure drop.
