CO2 footprint reduction with deployment of Net Zero futuristic bio-fuel technologies in-situ oil and gas refineries is prudent research area globally. India is primarily an agro-economy with varied crops generating annually 165MT of ligno-cellulosic-biomass like Rice husk, Wheat straw, Sugarcane bagasse etc. These are second generation bio-fuel source offering advantages over first generation food crops based bio-fuels without invoking food vs. fuel debate. Diversification of energy basket, Energy Poverty Alleviation and adopting Net Zero Technologies are drivers to promulgate bio-fuel technologies. India has gigantic 1.45 billion people (17.9% of world population) & around 100 million have limited access to clean energy and rely on low energy efficient polluting fuels like firewood, coal and cattle dung cakes for cooking. As per WHO, smoke emitted by these fuels causes smoky kitchens with CO, particulate matter, benzene, formaldehyde 1,3-butadiene and other noxious fumes adversely affecting women and children health causing respiratory disorders.
Present paper critically discuss CSR (Corporate Social Responsibility) initiatives of Indian Oil & Gas industry with responsibility of eradication of Nations’ Energy Poverty & upgrading Women Health via country wide Ujjawala program by enabling Clean LPG supply in rural areas PAN India.
Present paper also reviews spectrum of Futuristic Bio-fuel Technologies at various stages of development that are prudent to achieve Energy Affordability in India. Different thermo-chemical technologies like Fast biomass pyrolysis oil, Biomass Gasification, Biological Fermentation, Co-generation, Co-Firing of Bio-pellets, Pyro-Bio-oil Valorisation, Hydro-de-oxygenation, Hydrothermal Valorisation, Trans-Esterification Bio-Diesel, Bio-Butanol, Bio-Ethanol and Green Hydrogen via Biomass are analysed in context with low cost energy availibility to rural population & simultaneously making environment gree. It is technically discussed that LCA (Life Cycle Assessment) of Biofuels technologies establishes carbon neutral route while coupling renewable solar energy & CCUS (Carbon Capture and Utilization) portrays Bio-fuels technologies as carbon negative. Refinery integration challenges of these biofuel technologies with merits and demerits are analysed in context with eradication of energy poverty Across India with making common person index high on enegy affordability.
This Study encompass Robust capturing of innovation in Bio-Fuel Technologies & their demonstration in-situ oil and gas refineries & coupled bio-refineries. Upgrading Women Health via Ujjawala Clean LPG supply in rural India is also paramount arena of discussion. This study may set role model for oil and gas industry with focus on CO2 Footprint Reduction across global communities with holistic goal of eradication of Energy Poverty coupled with Net Zero, Energy Efficiency, Sustainability and Women Health worldwide.

Strategizing carbon neutral technologies & Ratification of International-Climate-Change Paris Agreement under UNFCCC, COP are critical drivers to promulgate carbon neutrality & holistic net Zero goal with Bio-gas as a potential candidate. Novel Heterogeneous Catalysis plays crucial role for selective oxidation of hydrogen sulphide (H₂S) to elemental sulphur (S) in bio-gas purification & is of paramount interest globally.
Bio-gas (primarily methane & carbon dioxide) is produced by Anaerobic Digestion (AD) of wet organic rich biomass. However, generated intermediate like hydrogen sulfide, ammonia, carbon dioxide, siloxanes & halogens lowers quality, selectivity & yield of harvested bio-gas. H₂S is notorious as it is toxic & corrosive. Selective Oxidation of H₂S to S using metal oxide-based catalysts (Vanadium & Iron oxides) & Carbon-based catalysts improves bio-gas quality, operational efficiency & prevents equipment damage.
Present paper critically reviews heterogeneous catalytic processes for Selective Oxidation of H₂S to elemental S in bio-gas contributing to sustainable & circular carbon economy. Advanced catalytic systems with robust reactor internals catering to optimised reaction parameters like temperature, O2/H2S ratio & H2O content affecting catalytic performance are analysed. Present paper elaborate parameters of catalysis in selective oxidation like catalyst efficiency, scalability, active sites regenerability, stability, adsorption strength, surface-to-volume ratio, metal-metal & metal support interaction & synergy of support with active metal sites being prudent factors of analysis including role of catalyst modifiers, inhibitors & enhancers.
Predictions of tailored heterogeneous active catalyst formulations for economic viability of selective oxidation technologies are elaborated with Noble/ non-noble catalysts support modifiers & enhancers (like magnesium, lanthanum, cobalt and chromium) that enhances gasification of coke precursors & slows coking surface reactions. Selectivity enhancement of catalysts by inhibiting thermodynamically unfavourable side reactions for desired conversion pathways; enhanced process energy efficiency due to more efficient catalysts with lower temperatures & pressures (due to altered activation energy); catalyst recyclability & reusability supplementing overall economics & environmental process impact; catalyst compatibility with impurities / contaminants laden feedstock and thereby being resistant to deactivation / poisoning by impurities and catalyst mechanism in bio-gas purification are discussed.
Study of Novel Heterogeneous catalysis for oxidation of H₂S to elemental S aims to establish that catalytic processes can be promising pathways for producing clean & industrially viable biogas & for pathways of producing VACs (Value Added Chemicals) from bio-gas. In Comparison, economic feasibility supplemented with positive green societal costs projects catalysis for biogas purification with in-situ integration of carbon neutral perspective. Hope this compilation will create lots of interest amongst researcher & practicing engineers active in Sulphur removal, Bio-fuels, Industrialist and environmentalist towards meeting net zero goals.
