Yield:-
Reaction Conditions:
with zinc doped zirconia nanoparticle dispersed on zeolite H-ZSM-5 at 399.84; under 15001.5 Torr; for 20 h;Catalytic behavior;Flow reactor;Pressure;
Steps:
Catalytic reaction.
General procedure: The syngas conversion was performed on a high-pressure fixed-bed flow reactordesigned by Xiamen HanDe Engineering Co., Ltd. Typically, the catalyst (1.0 or 3.0 g) with grain sizes of250-600 μm (30-60 mesh) was loaded in a titanium reactor (inner diameter, 10 mm). The syngas with aH2/CO ratio of 2:1 was employed in this work and Ar with a concentration of 4% contained in the syngaswas used as an internal standard for the calculation of CO conversion. The flow rate of syngas wasmanipulated at 25 cm3 min-1 (293 K, 101 kPa) for each reaction. The syngas pressure and the reactiontemperature were typically 3.0 MPa and 703 or 673 K, respectively. The product selectivity wascalculated on a molar carbon basis for CO hydrogenation. The MTA reaction was performed in the same reactor, and liquid methanol (0.060 cm3 hr-1) was fed into the reactor by a Series III Pump with N2 or COgas flow (6 cm3 min-1). The catalytic performances after 20 hr were typically used for discussion.Products were analyzed by online gas chromatographs (Ruimin GC2060, Shanghai), which wereequipped with a thermal conductivity detector (TCD) and two flame ionization detectors (FID). TDX-01packed column was connected to TCD, while HP-Pona and Rt-Q-BOND-PLOT capillary columns wereconnected to FID. The product selectivity was calculated on a molar carbon basis.
