Limestone was converted to high surface area CaO/MgO catalysts via calcination-hydration-dehydration (CHD) method for transesterification of coconut oil to biodiesel. Thermal?decomposition?at 900 degr...
Biodiesel obtained from mustard seed is found to be a promising alternative for petroleum diesel fuel owing to its similarity in physical and chemical properties. In this work, TiO2 nano-fluid which a...
Biodiesel from inedible sources has become prominent in last few decades. But it is economically incompatible with petroleum diesel. At the same time, both petro-diesel and biodiesels are concerned wi...
One of the most useful agricultural machinery is power tiller; this kind of tractor is widely used in small fields. The operators of this kind of machinery are exposed to high level of vibration. Lo...
The disposal of crude glycerol, the biodiesel by-product, may become an economic or environmental problem in cases where no trading of this material is possible. This study aimed at evaluating the dec...
An increasing number of countries and areas in the world suffer from either natural or anthropogenic dust, which results in a serious hazard with respect to the environment and to personal health and ...
A comparative study of biodiesel production from waste cooking oil using sulfuric acid (Two-step) and microwave-assisted transesterification (One-step) was carried out. A two-step transesterification ...
This study was carried out to produce biodiesel from methyl esters of groundnut (Arachis hypogea) oil and blend with Petrol diesel. The fuel quality of the biodiesel and its blend (B10) was assessed a...
This study investigates the size distribution of nano/ultrafine particle-bound PAHs (polycyclic aromatic hydrocarbons) and the PAH-associated carcinogenic potency/cytotoxicity of the exhaust from a g...
从非均相酸和碱催化转酯化反应的角度,综述了微波促进生物柴油制备的国内外研究进展。在微波辅助下非均相催化过程具有反应速率快、节能、环境友好、产物分离简便的优点。非均相催化剂以固体酸或者固体碱催化剂为主,反应在10~30min内完成,转化率与传统加热方式相当或者更高,所采用的固体催化剂具有可重复利用性。
通过酯交换实验制备了以新疆产的文冠果种仁油和棉籽油为原料的两种生物柴油。采用气相色谱方法对其脂肪酸甲酯组分进行了分析;考察了两种生物柴油的部分理化性质,并与0号柴油和国外生物柴油的标准进行对比。重点分析了生物柴油中脂肪酸甲酯组分分布对其理化性能的影响。实验结果表明,文冠果种仁油无需进行脱酸预处理,而各项理化指标均达到要求,更适合制备生物柴油。
The article explores the possibilities of using fatty acid methyl esters derived from the oil of a new species of oily plant Camelina sativa not demanding on soil. The performed research on the physic...
In order to investigate the influence of fatty acid methyl ester (FAME) on oxidative deterioration behavior of biodiesel mixed diesel fuel, FAME/tetradecane mixtures were prepared as model biodiesel/d...
Waste cooking oil contaminated with fish oil has potential uses as a biodiesel fuel feedstock. The changes in properties of fish oil fatty acid methyl ester (FAME) caused by oxidation were first evalu...
This paper discusses the influence of biodiesel on the injection, spray, and engine characteristics with the aim to reduce harmful emissions. The considered engine is a bus diesel engine with injectio...
