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 filter …
Syngas is a valuable intermediate in the chemical industry and can be produced from any carbonaceous source such as natural gas, coal, biomass or even organic wastes (Wender, 1996). The lowest production cost of syngas so far is based on methane and, hence, the main focus has been on using associated gas . Associated gas is a byproduct during ...

Two fundamental needs for improved anode materials are low irreversible capacity and long cycle life. Regrettably, early research discovered that many alloy anodes have large initial irreversible capacities (the difference between charge and discharge capacity) and fast capacity fading during cycling (reversible capacity loss) [8,9] Fig. 2.. depicts a …

2. CCE is commonly done at room temperature, which spares the thermolabile constituents from exposure to heat which is employed in most other techniques. 3. As the pulverization of the drug is done under wet conditions, the heat generated during comminution is neutralized by water. This again spares the thermolabile constituents from exposure ...
