Filtration
Filtration is a physical separation process that separates solid matter and fluid from a mixture using a filter medium that has a complex structure through which only the fluid can pass. Solid particles that cannot pass through the filter medium are described as oversize and the fluid that passes through is called the filtrate. Oversize particles may form a filter cake on top of the …
Hydrogen peroxide
Hydrogen peroxide (H 2 O 2) is a nonplanar molecule with (twisted) C 2 symmetry; this was first shown by Paul-Antoine Giguère in 1950 using infrared spectroscopy.Although the O−O bond is a single bond, the molecule has a relatively high rotational barrier of 386 cm −1 (4.62 kJ/mol) for rotation between enantiomers via the trans configuration, and 2460 cm −1 (29.4 …

Biomass
Biomass is plant-based material used as fuel to produce heat or electricity.Examples are wood and wood residues, energy crops, agricultural residues, and waste from industry, farms and s. Since biomass can be used as a fuel directly (e.g. wood logs), some people use the words biomass and biofuel interchangeably. Others subsume one term under the other.
Haber process
The Haber process, also called the Haber–Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today. It is named after its inventors, the German chemists Fritz Haber and Carl Bosch, who developed it in the first decade of the 20th century.The process converts atmospheric nitrogen (N 2) to …
