Basics :
CH4+ H2O-----800-1000 °C -----> CO+3H2 (1250 ° C in production of H2
)
CO+H2O ---- 500 °C -------> CO2 +H2 (catalyst Fe2O3 in production
of H2 )
Sum : 1 CH4 ---------> 4 H2 !
Invers : 3 H2 + CO ----300 °C + Ni catalyst -------> CH4 +H2O
4 H2 + CO2 -----300 °C + Ni catalyst -------> CH4 + 2H2O
Also 4CO + 2H2O -------- 275 +Ni catalyst ------> 3 CO2 + CH4
Mr Crispin ,mind closed box CARBIDES as surface steel hardening .900 ° C
Silicon Carbide , Calcium Carbide production ,the HIGH temperature is
needed .
To start the reaction .
Like : Ca O +3C ------2500 °C --------> CaC2 +CO
Carbon evaporation is not for stoves but in arc plasmas .
Old tric for chimney concrete :
Add 5% CaO to get less expansion problems .
Concrete glue is Na2SiO3 in presence of CaO or and Al (OH )3 .
Water in a parafin stove ( C12 H26 liniair ) may give a negative balance
.
But injection systems have a positive balance with 5% (? ) steam .
