Question

which kind of conversion uses heat to upgrade the
biomass
in fuel​

Answer 1

Answer:

Gasification converts biomass to a combustible gas mixture through partial oxidation of biomass at high temperatures of 800–900°C. It has traditionally received the most RD&D support as it offers potentially higher efficiencies compared with combustion.

Answer 2

Answer:

The answer is the thermal conversion

Explanation:

Biomass is commonly referred to as a biofuel because it is primarily used as a fuel for the generating of heat and power.

• Biomass energy is the energy derived from organic material derived from plants and animals. When biomass is burned, chemical energy is released in the form of heat.

• Crop wastes, forestry leftovers, industrial and municipal organic wastewaters, and so on are all examples of biomass.

The use of heat, with or without the presence of oxygen, to convert biomass into other kinds of energy and goods is known as thermal conversion.

• Direct combustion, pyrolysis, and torrefaction are examples of these processes
