(gasification or reforming processes) but the inherent separation of the two semireactions allows the production of carbon-free hydrogen.In this thesis, steam-iron cycle with methanol is proposed and three different oxides with the generic formula AFe2O4 (A=Co,Ni,Fe) are compared in order to...
Methanol, also known as methyl alcohol, wood alcohol, or carbinol, is a clear, colorless liquid with a slightly sweet odor. It is the simplest type of alcohol and has the chemical formula CH3OH. Methanol is highly flammable and toxic, and it should be handled with care. It is the ...

Chemical Formula of Propane Alkanes follow a general formula with a set ratio of carbon atoms to hydrogen atoms: C_nH2_n+2. The simplest alkane is methane, otherwise known as natural gas. It contains one carbon atom bonded to four hydrogen atoms. For methane,n= 1, so the number of hydr...
