What are liquid biofuels, its types, advantages and few facts to know about

As we all know, biofuels is a renewable, alternative clean fuel that is derived from plants, industrial waste, agriculture and domestic waste. It is a non fossil fuel produces from biomass. We have already seen Biofuels, its types and advantages. Now let us see what liquid biofuels are, its types, advantages and facts to know about liquid biofuels.

What are Liquid Biofuels?

Biofuels are converted to the required form by three ways; they are namely chemical process that uses chemical agents for the breakdown, thermal process that uses heat energy for the breakdown of raw material and biochemical process that uses bacteria for the breakdown of raw materials.  Biofuels can be broadly classified into solid biofuels and liquid biofuels. Solid biofuels are being used since ages for heating and lighting purposes. Some of the examples of solid biofuels include wood, sawdust, charcoal, agricultural waste, dry manure and firewood. Solid biofuels are also known as primary biofuels. Liquid biofuels on the other hand is used widely in industries and automobiles. Some of the commonly used liquid biofuels are biodiesel, bio ethanol, biogas, Biobutanol and biohydrogen. The energy released from biofuels is known as bioenergy.

Types of Liquid Biofuels


Bioethanol is one of the most promising liquid biofuels. It is a renewable source of energy that can be easily produces from fermentation of sugar from crops. In the fermentation process, the sugar required is from the energy crops. The commonly grown crops are corn, wheat crops, sorghum, maize, willow, reed canary grass and cord grasses. The production process of Bioethanol is as under;

Bioethanol can also be produced from wheat grains. The process is an under;


Biodiesel is another liquid biodiesel that is easily renewable. It is easily produces from waste animal fat and vegetable oil. It is biodegradable and causes very less pollution during burning. It can be mixed with petroleum diesel for vehicles. Cooking oil, animal fat and agricultural byproducts are the major ingredient that is used in the making of biodiesel. These ingredients go through a chemical process where in which the glycerin is extracted. The process of removal of glycerin is called transesterification. The end products of this reaction are methyl esters commonly known as biodiesel and glycerin that are widely used in the making of soaps. This biodiesel is being used in diesel engines with very little modifications. One of the major attractions of using biodiesel is that it helps to release dirt from the engines which otherwise accumulate fuel pipes and walls. This in turn reduces the capacity of the vehicle and even clogs the filters. The energy content in biodiesel is about 90% that of petroleum.


Facts to know about liquid biofuel:


Liquid biofuels can be considered an asset to the economy. Considering its availability, more in-depth studies and research should be conducted so that it can be wisely used. Awareness program should be conducted so that more people will know the benefits of using liquid biofuels. It can also be used as an alternative for diesel and petrol which will reduce the monopolization of fuel. Thus this renewable resource is a boom to the economy as a whole.
