Abstract:
The methanation of a real gas produced from almond shells via steam/oxygen gasification is investigated. The performance of an experimental Ni-containing catalysts (Ni23.7Mg56.3Al20) was evaluated by using the material prepared in grains of 1-2 mm. The real gas was enriched with hydrogen at two different H2/COx mole ratios. All tests were carried out at operating conditions of 400 ÷ 450 °C and 25 bara. Checks with a defined reactive gas mixture provided indication about the activity state of the catalysts before and after the methanation. During all the stages of the tests the outlet gas composition was monitored and after each complete run the catalyst analyzed. Under the operating conditions adopted, the experimental catalyst showed a higher methane yield (+10% and +44%) at both H2 enrichment levels and no carbon deposition was observed, as demonstrated by after-test catalyst samples evaluated via Raman spectroscopy coupled with optical microscopy and SEM-EDAX analysis.
