Production of methanol is achieved in a continuous high pressure flow reactor using methane, carbon dioxide and hydrogen as reagents at 250 oC, 25-80 bar (GHSV = 40000 mL CO2/g.h). The results confirm the potentialities of the bimetallic oxides and intermetallic compounds containing f-block elements as catalysts, especially when compared with the behavior of a commercial Cu methanol synthesis catalyst.
Different protocols tested by using absorbed and regenerative luminescence measurements applied to single and multiple aliquots of micro samples of ceramics fractions enriched in quartz grains, showed that single aliquot regenerative-thermally stimulated luminescence (SAR-TSL) protocol is the most appropriate for the determination of the absorbed dose for the luminescence age calculation
