Ammonia has been expected as hydrogen and energy carriers because it has high gravimetric and volumetric H 2 densities with 17.8 wt% and 10.7kgH 2 /100L, respectively. The volumetric hydrogen density is above 1.5 times of liquid hydrogen, and it is easily liquefied under 1MPa at 298K. ...
- 《Journal of the Physical Society of Japan》 被引量: 0发表: 2008年 Reduction of SO2 emissions by ammonia gas during unstaged combustion When ammonia is added in the main combustor zone, the temperature is much higher than that required for the occurrence of sulphur dioxide-ammonia and ...
Water is the most plentiful compound on Earth and is essential to life. Although water molecules are simple in structure (H2O), the physical and chemical properties of water are extraordinarily complicated. Also known as: H2O Written by
Purification and properties of crystalline 3-methylaspartase from two facultative anaerobes, Citrobacter sp. strain YG-0504 and Morganella morganii strain YG-0601. 3-Methylaspartase (3-methylaspartate ammonia-lyase, EC 4.3.1.2) from two facultative anaerobes from soil, Citrobacter sp. strain YG-0504...
The technologies used were nonammonia and ammonia method. The sugar as raw material was the white granulated sugar of the best quality, the glucose of the first grade and the invert sugar. The normal properties and the other properties such as isoelectric point and colloidal property were ...
Property of Matter: The matter has mass and occupies volume. There are two types of property of matter, these are chemical property and physical property. Properties are a measurable quantity of matter. Answer and Explanation:1 The difference between physical and chemical properties of matter : ...
Functional diversity rather than species richness is critical for the understanding of ecological patterns and processes. This study aimed to develop novel integrated analytical strategies for the functional characterization of fish diversity based on th
The parameters measured were: electrical conductivity, pH, alkalinity, temperature, dissolved oxygen, total dissolved salts, sodium, magnesium, calcium, potassium, fluoride, chloride, nitrate, ammonia, sulphate, phosphate and silicate. The physical and chemical properties are mostly affected by artificial...
The underlying goal of assessing the chemical and physical properties of a lubricant is to determine its performance characteristics. Lubricants are used for a myriad of different reasons, though all share the same goal of maximising efficiency. Below, we spotlight some of the ...
molecular structureA ball-and-stick model of molecular structure, showing atoms bonded together. Although simple models of bonding are useful as rules of thumb for rationalizing the existence of compounds and the physical and chemical properties and structures of molecules, they need to be justified ...
