RENEWABLE AND NON- RENEWABLE ENERGIES BIOMASS
ability to cause a change in matter
biggest source of energy is a sun
is the organic animal and plant matter used for energy:
any type of biomass comes from the reaction of plant photosynthesis that takes advantage of the energy of the sun
TYPES OF BIOMASS
Energy crops: such as corn and sugarcane used to obtain bioethanol
Waste: from agricultural and livestock activities
found in nature in limited quantity, these cannot be substituted
inexhaustible natural sources for their large amount of energy and are capable of regeneration. unlimited*
BIOMASS TO BIOGAS
they are simple machines that convert
into usable by-products
Parameters for a biodigester:
:check: longer retention time, higher methane content.
:check:low fermentation temperatures, high percentage of methane = less gas
:check:pH approx. 7
HOW DOES IT WORK
complex organic: proteins, carbohydrates and lipids.
Simple organic: sugars, amino acids, peptides.
Long chain fatty acids: propionic, butyric (volatile) alcohols.
TYPES OF BIODIGESTORS
Biogasification can be designated as a methane fermentation, which consists of the destruction of lean gas by microbial fermentation in anaerobic digestion.
Formation of methane:
FACTORS INFLUENCING ANAEROBIC DIGESTION
:check: carbon / nitrogen ratio
:check: pH control
:check: suitable bacteria system
