Fig. 2: Catalytic performance of tandem catalysts.
From: CO2 hydrogenation to acetic acid and methyl acetate via tandem catalysis
a Catalytic performance of different catalyst modes. Reaction conditions: H2/CO2/Ar = 71.25/23.75/5, T (upper bed) = 623 K, T (lower bed) = 558 K, P = 5.0 MPa, GHSV = 1200 mL gcat−1 h−1. Catalyst loading for upper bed: 0.5 g of GaZrOx. Catalyst loading for lower bed: M1, 0.5 g of MOR-8; M2, 0.5 g of MOR-8-C1; M3, 0.5 g of MOR-8 and 0.5 g of PC; M4, 0.5 g of MOR-8-C1 and 0.5 g of PC. b Photographs of the catalyst beds with different modes. HCs hydrocarbons, DME dimethyl ether, MA methyl acetate, AA acetic acid. The selectivity of organics was calculated on a molar carbon basis (CO free). The error bars represent the relative deviation within three independent experiments, which is within 3%.
