Odia scientist-led team develops tech for producing biofuel

The present scenario calls for production of biofuels using green technology.  The term biofuel is referred to as liquid or gaseous fuels that are predominantly produced from biomass. Biofuels are important because they can replace petroleum based fuels.

Biofuels are generally considered as offering many priorities, including sustainability, reduction of greenhouse gas (GHG) emissions, regional development, social structure and agriculture, and security of energy supply, says Dr Sanjib Kumar Karmee, Principal Scientist and Head of Thermo-Chemical Conversion Division Sardar Patel Renewable Energy Research Institute Anand,Gujarat.

In the above context, biomass, in particular forestry (sawdust) and agricultural wastes, are best sources to meet the energy demands of the future as it is not only renewable but also environmentally friendly ,says Dr Karmee further.

The energy obtained from biomass is used mainly for heat production, electricity, and as liquid fuels for vehicles. Various advanced technologies have been developed to obtain biofuels and chemicals from biomass, which include the hydrothermal process, pyrolysis and combustion.

Pyrolysis of biomass is one of the most efficient technologies used to produce biofuels. The process is carried out at elevated temperatures under an inert atmosphere which is maintained using either argon or nitrogen gases. The process generates bio-oil, biochar (solid), and pyro-gas (gaseous products), explains Dr Karmee further.

To conduct pyrolysis experiments the Sardar Patel Renewable Energy Research Institute has designed and developed a new pyrolysis plant to produce biofuels from saw-dust and agro residues. A team led by Odia Scientist Dr  Karmee  has demonstrated that biomass can be successfully converted into biofuels using both batch and pilot scale system. The newly developed pilot system has important industrial significance since it can operate at 15 kg/hr scale. The results of these experiments are published in the Fuel journal (Elsevier), informs Dr Karmee further.

Bolangir, July 8 (LocalWire): A scientific team in Gujarat led by an Odia scientist Dr Sanjib Kumar Karmee has now developed a machine which can produce fuels from biomass.

The plant was designed by the team at the Sardar Patel Renewable Energy Research Institute, Anand (Gujarat).

The plant has the capability to conduct pyrolysis of sawdust and agro residues to produce biofuels.

Karmee works at the Thermo-Chemical Conversation Division of the institute.

The scientific team has demonstrated that biomass can be successfully converted into biofuels using both batch and pilot-scale systems.

“The newly developed pilot system has important industrial significance since it can operate at a pace of 15 kg/hr scale. The results of these experiments are published in the Fuel journal (Elsevier),” said Dr Sanjiv Kumar Karmee further.

Local MLA and Congress Legislature Party Leader Narasingha Mishra on Tuesday called upon people to plant more trees to protect environment and meet climate change challenges.

He was speaking at a Bana Mahotsav at Khamarmunda organised by the Balangir Forest Range. He planted an Amla tree on the occasion.

He stressed the need to plant locally-suited and medicinal plants like Bahada, Arjuna and Amla trees.

DFO Sameer Satpathy claimed that forest cover in the district has increased. He said a plantation programme would be undertaken to plant trees on a four-km stretch of National Highway divider beginning from the Balongir Collectorate. Assistant Conservator of Forest BC Roul briefed about the Bana Mohotsav. Social distancing and other Covid norms were followed.
