The latter value is expressed with regards to the Lower Heating Value (LHV) of hydrogen.
The maximum system efficiency based on lower heating value (LHV) is 37% at 120.7 W.
The lower heating value of product gas was 4 5 MJ/m3 using herb residues as feedstock.
The result was that lower heating value and element composition did not depend on circumference size.
The enthalpy of reaction represents 31% of the lower heating value (LHV) of the absorbed hydrogen.
Biodiesel has a 5.95% increasing in brake-specific fuel consumption due to its lower heating value.
It is also demonstrated that the proposed configuration leads to a net lower heating value efficiency of 33%.
And lower heating value (LHV) together with Wobbe index of SNG are separately 31.66 MJ/Nm3 and 45.90 MJ/Nm3.
The lower heating value, the volumetric gas yield, the gas power and the cold gasification efficiency were the output variables.
This resulted in world-class solar to hydrogen efficiencies as high as 9.3% (based on H2 lower heating value, LHV).
