2. Catalytic Tests
Figure S4. Temperature dependence of 2,5-dMF and ethylene conversion over SiO2 (left) and SiC
(right) as derived from the MS analysis. Observed spikes correspond to GC injections.
Figure S5. Deoxygenation selectivity towards water in the aromatization reaction of 2,5-dMF and
2,5-dMF with co-feeding of ethylene over HZSM-5 and 4%Ga(HT) catalysts. Conditions: T = 450 °C;
p(2,5-dMF) = p(C2H4) = 0.2 kPa in 100 ml/min Ar.
