Two-stage thermophilic anaerobic co-digestion of cattle manure and corn stover was conducted to increase biomethane production. The first stage pre-digestion studied based on the following treatment variables: liquid fraction digestate (CS:LFD) ratio (1:7, 1:10, 1:13, 1:14), digestion temperature (55 °C, 60 °C) time (3, 7, 14 days). reduction in lignin, cellulose hemicellulose (LCH) between 3.97% 11.98%, which increased biodegradability stover. Corn pre-digested with a CS:LFD 1:10 at 55 °C...

Biodiesel has become a promising alternative biofuel that exhibits problems like high cost of feedstock, poor atomisation due to viscosity, stability issues, flow properties and NOx emissions as compared conventional diesel. Alcohols have recently drawn much attention low that, exhibit cetane number miscibility issues. Addition fuel additives, for example, diethyl ether (DEE), may be effective overcome the with biodiesel or alcohols. In this work, influence DEE on engine performance were...

The use of lower alcohol (such as methanol and ethanol) blends in diesel engines shows problems like phase separation, miscibility, higher NOx emissions etc. addition alcohols with either or biodiesel is relatively new only a little information available on the effects alcohols. In this work, engine performance characteristics were compared between blended biodiesel. Conventional are considered reference fuels. Three (methanol, ethanol propanol) three (butanol, pentanol octanol) each 50% by...

Thermophilic anaerobic digestion (AD) of cattail followed by hydrothermal carbonization (HTC) was studied. The intent the research to develop agricultural waste-based biorefining technologies for bioenergy production along with value-added products. Cattail anaerobically digested at 55 °C 14 days and protein cellulose components were partially degraded. average methane yield 230–280 mL/g volatile solids total decreased 33–55%. When particle size reduced from 1 in. mm, lag phase shortened...

Stringent emission regulations and health awareness about air pollution have led researchers to find alternative means of minimising emissions in diesel engines. In this article, the influence oxygen enrichment is discussed determine effect on engine performance, characteristics combustion characteristics. Normal oxygen-enriched are used experiment. The increase concentration complete combustion, producing higher thermal efficiency low harmful emissions. From results, it noted that fuel...

Energy utilisation from renewable sources plays a vital role in meeting the demands of clean environment. Commercialisation biodiesel is comparatively less than that other alternative due to its suitability and yield. This paper focused on performance emission characteristics neem oil cotton seed blended with cerium oxide as an additive. The blending proportion was B10, B20, B30, B40 100% diesel. testing performed single-cylinder diesel engine coupled exhaust gas analyser. were obtained...

Abstract Feeding strategy and diet are increasingly recognized for their roles in governing primate gut microbiome (GMB) composition. Whereas feeding reflects evolutionary adaptations to a host's environment, is more proximate measure of food intake. Host phylogeny, which intertwined with strategy, an additional, often confounding factor that shapes GMBs across host lineages. Nocturnal strepsirrhines intriguing underutilized group examine the links between these three factors GMB Here, we...

Nanofuel refers to the fuel that contains nanoparticles at very low concentrations. The addition of metallic had proven their effectiveness in improving engine performance and reducing emissions diesel/biodiesel blends fueled engines. However, emission these themselves through exhaust gases atmosphere may cause adverse health hazards. organic on biodiesel is relatively a new concept, which has potential overcoming toxic effects while imparting benefits using nanoparticles. In this research...

Nowadays, global warming, environment pollution, and limitations in energy resources have appeared as a serious crisis. Therefore, efficiency conservation are necessary all energy-consuming devices, such heating, ventilating, air conditioning (HVAC) systems. The aims of this project to evaluate the performance conventional system also compare its with proposed HVAC system, which consists heat recovery unit reduce initial capital cost electricity consumption system. Through hour-by-hour...

Biodiesel has become one of the potential alternative sources to replace diesel. Some limitations biodiesel include high NO x , poor atomization, oxidation stability, cold-flow problems, long-term storage etc. Various strategies were discussed overcome biodiesels. Recent research is on effects fuel additives or composition modification reformulate properties. This article aimed at presenting experimental investigation isobutanol additive engine performance and emission characteristics blends...

The shortage of drinking water has become one the biggest problems in world. Water pollution increased considerably because factors such as population growth, industrialisation and urbanisation. Several new technologies have been invented for desalination from time to solar distillation is considered more economical. In this work, influence Fresnel lens on conversion polluted industries into was investigated using double slope single basin still. industrial waste (of pH value 14) used still...

The main purpose of this study was to adapt proper methoding models improve the cast ability and reduce defects in casting. According many researchers, 90% casting are due wrong design gating riser systems 10% defects. Here we improving runner placement through process. In present work, validate advantages methoding, have selected model with without temperature distribution over various positions been analysed it is found that provides uniform distribution.

In advanced gas turbines, the turbine blade-operated temperature is above melting point of blade material. A sophisticated cooling scheme must be developed for continuous safe operation turbines with high performance. This report describes development and application a validated computational fluid dynamics (CFD) modelling approach internal passages in rotating turbomachinery which analyse change pressure, velocity, temperature, pressure passage. Velocity changes passage help to determine...
