A continuous process for the transesterification of triglycerides to methyl esters was investigated in a pilot plant. The process was equipped with a motionlerr and a high-shear mixer. The experimental studies explored variations in the mixing intensity, stcichionetry, and catalyst concentration on the overall conversion. The combined as well as individual effect of mixers was examined. The dev...

Alcohols have been used as a fuel for engines since 19th century. Among the various alcohols, ethanol and methanol are known as the most suited renewable, bio-based and ecofriendly fuel for spark-ignition (SI) engines. The most attractive properties of ethanol and methanol as an SI engine fuel are that it can be produced from renewable energy sources such as sugar, cane, cassava, many types ...

Biodiesels, which are made from various crops, as well as animal fat, are renewable, bio-degradable, and non-toxic and are eco-friendly compared with fossil fuels. Currently, there are more than 350 oil-bearing crops identified as potential sources for biodiesel production. In this study, the potential of biodiesel obtained from a non-edible oil source (Moringa oleifera) was explored and compar...

Assessment of gamma emission tomography (GET) for spent nuclear fuel verification is the task in IAEA MSP project JNT1955. In line with IAEA Safeguards R&D plan 2012-2023, the aim of this effort is to “develop more sensitive and less intrusive alternatives to existing NDA instruments to perform partial defect tests on spent fuel assemblies prior to transfer to difficult to access storage". The ...

In this paper, raspberry hollow Pd nanospheres (HPNs)-decorated carbon nanotube (CNT) was developed for electro-oxidation of methanol, ethanol, and formic acid in alkaline media. The electrocatalyst was fabricated simply by attaching HPNs onto the surface of CNT which had been functionalized by polymer wrapping. The as-prepared HPN-CNTs (CHPNs) were characterized by transmission electron micros...

The electronic structures and transport properties of a series of actinide monocarbides, mononitrides, and dioxides are studied systematically using a combination of density-functional theory and dynamical mean-field theory. The studied materials present different electronic correlation strength and degree of localization of 5f electrons, where a metal-insulator boundary naturally lies within. ...

Fuel vapour composition and flammability properties of E85 A series of experiments have been conducted to study the flammability characteristics and determine the flammable temperature range of E85 fuel vapours. E85 is a mixture of ethanol and petrol the composition varies depending on time of the year. According to the Swedish standard, SS 155480:2006, the ethanol content may not be below 70 %...
