Olive Waste Valorization Through TGA-MS Gasification: A Diatomaceous Earth Effect

The effect of diatomaceous earth on gasification olive pomace and stone was studied by thermogravimetric analysis with mass spectrometry (TGA-MS). Additionally, gas emissions, the H2/CO ratio, reactivity were evaluated. First, a preliminary study particle size waste performed to select most appropriate from technical industrial point view. With pomace, larger size, lower reactivity. However, stone, optimum results observed largest particles. Subsequently, mixed different percentages (10, 25, 50 wt %) earth. When contained earth, even though there no substantial improvement in reactivity, syngas quality terms significantly enhanced increased up four times. more remarkable, enhancing both ratio. Different behaviors biomasses due impacts alkali alkaline metals Whereas these made positive contributions only latter had significant influence pomace.
