A very huge amounts of fruit wastes are available as sugar laden world over. In fact, there is a need to recover value added products from these wastes. Fruit rich in sugars and carbohydrates which can be recovered utilized for the production bioethanol. Gasoline being used at scales globally. Therefore, plenty bioethanol would required produced if has replace gasoline fuel. Present studies directed towards finding cost effective ways starting initially without using any acidic or enzyme...
In the present work, graphene was synthesized by catalytic reduction of carbon dioxide (dry ice) in presence magnesium flame supported zinc and nickel metal respectively. The use Nickel resulted improvement yield. multiwall nanotubes (MWCNTs) were from pongamia oil CVD setup. MWCNTs characterized different characterization techniques such as scanning electron microscopy, transmission Raman spectra X‐ray diffraction study. Thus have been used conductive filler polystyrene (PS)/graphene...
Attempts have been made to understand the non-isothermal kinetics of cracking Jatropha oil (JO), vacuum residue (VR) and high density polyethylene (HDPE) their combined co-cracking using different heating rates 5 K min− 1, 10 15 1 20 under nitrogen (N2) atmosphere. The Flynn–Wall–Ozawa Kissinger–Akahira–Sunose (KAS) models were employed study kinetic analysis samples. To evaluate exponential factor model fitting Coats –Redfern approach was used. distribution activation energy for these...
Coal still remains an important source of power generation world over. Along with its usage, comes unwanted noxious gas emissions, toxic metal releases into wastewater and other pollutants which ultimately lead to environmental concerns. So cleaning coal through physical or chemical processes becomes utmost important. There are several coals cannot be cleaned by beneficiation techniques produce low ash cleaner coals. Such can only techniques. The present paper reviews the demineralisation...
Thermal decomposition of petroleum vacuum residue (XVR), polypropylene (PP), Bakelite (BL), Samla coal (SC), bagasse (BG), Calotropis procera (CL, a petrocrop), and their mixtures with was studied in batch reactor under isothermal conditions at atmospheric conditions. The product distribution patterns have been determined. Kinetics thermal were also order to compare the kinetics cracking individual materials that mixture. Activation energy as well rate constants calculated for mixtures....
Abstract Due to growing environmental concerns, eco‐friendly processes and materials have become one of the key interests research in area tribology, natural esters are gaining popularity as lubricants. Natural being used many applications lubricant base. In Europe, canola/rapeseed oil sunflower mainly used, whereas USA, soybean is use for formulating environmentally friendly Native genetically modified high oleic varieties these oils widely used. Indian scenario, since above‐mentioned...
This article reviews the literature reports based on polystyrene nanocomposites using nanoclay as filler. The use of various clay surfactants and different processing conditions, i.e., in situ polymerization, melt intercalation solution casting used for preparation its effect properties morphology is also reviewed.
Abstract The use of low-grade coal in thermal power stations is leading to environmental pollution due the generation large amounts fly ash, bottom and CO2 besides other pollutants. It therefore important clean before using it stations, steel plants, or cement industries etc. Physical beneficiation results only limited cleaning coal. increasing problems from have led development technologies. In fact, requires ultra low ash contents, keeping norms view ever-growing need increase efficiency...
To fulfill the need of renewable, sustainable, and cleaner form fuel, scientists are attracted toward biodiesel hydrotreated vegetable oil or green (renewable) diesel. Biodiesel is generally obtained from by process transesterification while diesel hydrogenation. However, chemically both completely different thus their physical properties highly affected. In present work, authors have compared important Pongamia biodiesel, algal oil. It observed that biofuels may be blended for use in...
