Question

is preparation of biofuel a chemical or physical process why

Answer 1

It is a chemical process

The process is known as transesterification. It involves the addition of methanol to vegetable oil which will react chemically.


A catalyst, Potassium Hydroxide or Sodium Hydroxide, is usually used in this process to speed up the rate of chemical reaction


The catalyst is recovered completely unaffected at the end of the process.

Answer 2

Answer: Preparation of biofuels is a chemical process.

Explanation:

When biomass is converted into liquid fuel then that fuel is known as biofuel.

For example, preparation of biodiesel is known as transesterification. In this process, methanol is added to vegetable oil in the presence of a catalyst. This catalyst is alkaline in nature. This catalyst along with the glycerol is removed from the vegetable oil. Further, after several steps biodiesel is obtained.  

Therefore, preparation of biofuels is done with the help of chemical reactions. Thus, we can conclude that preparation of biofuels is a chemical process.
