chemical decomposition of water in a double-stage CO2 cycle.
For these processes, efficiencies above 50 % can be expected and could possibly lead to a major decrease of hydrogen production costs. The main technical issues for these high-temperature processes relate to materials development for corrosion resistance at high temperatures, high-temperature
membrane and separation processes, heat

the charge material - a molecular species that contains the desired element - is a gas at room temperature. (Liquids with an appreciable vapor pressure at or near room temperature may also be used.)
A standard gas handling system connects the external gas canister to the growth chamber.

this, we can know that axial impeller is not suitable. Also, because of wide width of tank, it has poor mixing.
Second, there is a problem with chemicals. PAC is injected with Cl2, so activation of Cl2 must be restricted.
Also, using alum may cause settling.
Alum lowered pH in localized area. To overcome this problem, we need more alkali materials and it means lots of cost.
What is Bioenergy?
Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.
So, Why do we produce Bioenergy?
One reason governments
