We consider olive pomace + grape pomace gasification (or biomass co-gasification) in the presence of oxygen or air (gasifying agent).
Here, we determine the Equivalence Ratio (ER) when we feed the gasifier with 1 mol of each one of the two biomasses and 1 mol of pure O2 knowing that olive pomace is modeled as a pseudo-compound whose formula is while grape pomace is modeled as .
Next, we determine the Equivalence Ratio (ER) when we feed the gasifier with 1 mol of each one of the two biomasses and 5 mol of air.
