The Developed System of Continuous Utilization of Carbon Dioxide, Enrichment of the Atmosphere with Oxygen and Production of Biofuel Using the Resulting Concentrate of Rapidly Multiplying Microalgae
Abstract: It is known that microorganisms, such as microalgae, during photosynthesis utilize carbon dioxide and enrich the atmosphere with oxygen. Microalgae, on the other hand, can be converted into biofuels by extracting fatty acids from macromolecules known as lipids. Recovery of this fatty acid traditionally requires the removal of most of the water from the microalgae resulting in biomass slurry. The method developed earlier permitted to obtain a high-quality concentrate of …

H2 Production by Methanol Steam Reforming over Copper Impregnated Anodized Aluminum Oxide (AAO)
Abstract: Hydrogen production by methanol steam reforming (MSR) is easy and simple as compared to other reforming methods using fossil fuels such as methane steam reforming. The catalysts for MSR are well developed and available commercially. When constructing a small or micro reformer, the catalyst often needs to be coated on the wall of the metal substrate. In this case, the bonding between the metal surface and the catalyst layer must …

Modeling and Simulation of Spiral Plate Heat Exchanger
Abstract: The spiral-plate heat exchanger (SHE) offers efficiency in spacing and reduces heat losses. SHE’s offer high reliability, lower spaces occupancy, high heat transfer coefficient and on-line performance in many severely fouling services such as slurries. Experimental investigations were conducted in a spiral plate heat exchanger with hot water as the service fluid and cold water in different flow rates as the cold process fluid. The experiments were conducted essentially in …

Use of Liquefiable Materials for Vibration Isolation
Abstract: Abstract Trench barrier isolation is very popular but less adopted technique for the isolation of buildings and important structures. Here the structures are to be protected against the energetic surface waves, which are confined up to 3–4.5 m depth below the surface. Several types of trenches with different in-fill materials have been tried with some degree of success. The difficulty comes from the nature of the waves, which are a …

Studies on Biological Degradation of 4-Bromophenol Using Anaerobic, Anoxic and Aerobic Bioreactors
Abstract: The present study investigates biodegradation of 4-Bromophenol (4-BP) and simultaneous removal of COD in anaerobic, anoxic and aerobic moving bed bioreactors. Cow dung slurry was used as a source of microbial consortium for acclimatization in moving bed reactors in batch mode. The acclimated microbial consortium was able to degrade various concentrations such as 5, 10 and 15 mg/l of 4-BP within specific time period. Biodegradation was evaluated by determining total …

Thermophilic Adaptation of Anaerobic Sludge for Electricity Production
Abstract: Normal 0 false false false EN-US X-NONE X-NONE Anaerobic digestion of biogas inside the digester occurs in a particular temperature range. Research shows that the production can be increased by 33% by switching over from mesophilic temperature range (3040 ° C) to thermophilic temperature range (5060 ° C). Even then, biogas plants generally work in mesophilic range because a large amount of energy is required to maintain the high digester …

Improvements in Wear Resistance by Hardfacing
Abstract: Wear of hardfacing appears from additive effects of abrasion, erosion, corrosion and impact in real cases where material under handling varies between dry states to damp/slurry state. Abrasion of hardfacing is a study of gouging abrasion, high stress grinding abrasion, and low stress scratching abrasion or erosion. Impacts of abrasive particulates induce additive effects to wear and material loss by embrittlement effects of carbides. Corrosion of hardfacing appears from galvanic, …
