Preliminary Investigation into the Cold Plasma Powered Water Gas Shift Reaction – Experiments And Analysis
Water gas shift reaction (CO + H2O ↔ H2 + CO2) is a CO oxidation reaction in the presence of steam resulting in the formation of H2 and CO2. Traditionally, water gas shift (WGS) reaction is achieved using multiple catalytic ... -
Valorization of Residual Ligno-celluloses from Anaerobic Digesters Through Product Recovery
Complete digestion of lignocellulosic biomass during anaerobic digestion (AD) is impossible due to recalcitrance created by lignin, consequently leaving behind a significant part of the feedstock unconverted to methane. ... -
Modeling and Analysis of Hybrid Renewable Energy for Power Generation
Renewable energy-based power has gained significant global momentum—to minimize fossil-fuel use, combat climate change, and ensure energy security. While renewable energy (RE) is fast-growing, stand-alone single resource-based ... -
Studies on Processed Granulated Blast Furnace Slag as Fine Aggregate in Mortars and Concrete
Fine aggregate is essential for the preparation of mortar and concrete. There are attempts to find alternatives to the river sand as the natural sources for fine aggregates are dwindling. Currently, sand mining from river ... -
Lignin and Extractive Tracing - an Alternative approach to Assess and Predict Biogas Yields and Production Rates among Tropical Biomass Feedstocks
Predicting biogas yields from the composition of biomass feedstocks has been difficult primarily due to the variations found in their chemical composition and structure of lignocellulosics. This study aims at understanding, ... -
Prospects of Bioethanol from Estuarine Macroalgae
Burgeoning dependence on fossil fuels for transport and industrial sectors has been posing challenges such as depletion of fossil fuel reserves, enhanced greenhouse gas (GHG) footprint, and imminent changes in the climate, ... -
Fate and Remediation of Ammonium-n In Pit Toilet Blackwater
Pit toilets satisfy the sanitation requirement in regions with no access to piped sewerage facilities. Black water discharged from pit toilets is a major source of groundwater pollution. The primary focus of the thesis is ... -
Sustainable and Energy Efficient Treatment Potential of Mixed Algal Consortia for High Nutrient Organic Wastewaters
The increasing levels of generation of nutrient rich wastewaters around the world pose serious challenges where conventional biological and chemical methods of treatment have gradually begun to fail in meeting sustainability ... -
Evaluation of Btex Contamination in Bengaluru Groundwater and Remediation of Contaminated Water Samples
BTEX (benzene, toluene, ethylbenzene, and xylene isomers) are monoaromatic, volatile organic compounds (VOCs) with single benzene ring and various degree of alkylation. US EPA classifies benzene and TEX (toluene, ethylbenzene, ... -
Bioremediation of Mechanically and Biologically Treated Waste Of Bangalore City: An Experimental and Numerical Study
Remediation of the existing MSW dumpsites has received considerable attention these days and there is an urgent need to address this issue in order to maintain the over hygiene of the urban environment. An approach consisting ... -
Syngas Fueled Solid Oxide Fuel Cell (Sofc) – Experiments and Analysis on Gas Characterization and Cell Performance
The present research addresses the complexities involved in the use of syngas as a fuel in a Solid Oxide Fuel Cell (SOFC). Solid oxide fuel cell is an efficient, clean direct energy conversion device. Being a fuel flexible ... -
Algiculture - A Novel Algae Cultivation Technique for Sustinable Algal Biofuel Production and Capture of Green House Gases
Algal biofuel has been shown to have great potential to solve the World’s sustainable energy crisis but technologies for large-scale cultivation are still elusive. While photobioreactors meet very high value algal products ... -
In-Cylinder Experimental and Modeling Studies on Producer Gas Fuelled Operation of Spark Iginited Gas Engines
(2018-08-10)The current work, through experimental and numerical investigations, analyses the process and cycle level deviations in engine response on fuelling multi-cylinder natural gas engines with producer gas. Producer gas is a ... -
Evaluation of the Engineering Properties of Municipal Solid Waste for Landfill Design
(2018-07-18)The objective of this thesis is to evaluate the engineering properties of Municipal Solid Waste (MSW) that are necessary in the design of landfills. The engineering properties of MSW such as compressibility, shear strength, ... -
Vulnerability of Forests to Climatic and Non-Climatic Stressors : A Multi-Scale Assessment for Indian Forests
(2018-06-05)During the 21st century, climatic change and non-climatic stressors are likely to impact forests leading to large-scale forest and biodiversity loss, and diminished ecological benefits. Assessing the vulnerability of ... -
Effect of Extractives and Crude Proteins on the Kinetics of Hydrolysis in a Solid State Bio-Reactor
(2018-04-18)Polymer hydrolysis is the first (and rate limiting) step for biomethanation of heterogeneous biomass feedstock’s. Satisfactory hydrolysis has been difficult to achieve, understand and predict adequately, to run anaerobic ... -
Studies on Modified Clay Additives to Impart Iodide Sorption Capacity to Bentonite in the Context of Safe Disposal of High Level Nuclear Waste
(2018-03-03)It is a generally agreed internationally that high level nuclear wastes containing long-lived radioactive wastes should be disposed in deep and stable geological formations that are 500-1000 m below ground level. Deep ... -
