Steps:
2.3. OA Deoxygenation experiments
General procedure: Gas-phase catalytic deoxygenation of OA was investigated using an atmospheric pressure, fixed-bed micro-reactor equipped with dual on-line gas chromatographs. The apparatus is illustrated schematically in Fig. 1. The reactor consisted of a 0.5 in. OD stain-less steel tube containing 0.5 g (typ.) catalyst powder suspended between quartz wool plugs. The reactor tube is mounted vertically in a single-zone tube furnace (Lindberg) with PID controller(Eurotherm). Catalyst temperature was measured using a Type Kthermocouple in direct contact with the bed. Each catalyst wasreduced in situ at 300C for 1 h in flowing H2(100 sccm). Gas flowrate and composition to the reactor were set by mass flow con-trollers, and liquid OA was fed by syringe pump (ISCO Series D)and evaporated prior to entering the reactor. Typical feed condi-tions were 4 L/min OA injection rate and 100 sccm total gas flowrate. The total gas flow rate, H2partial pressure, reactor temperature, and OA injection rate were adjusted, as indicated, during the investigation. The reactor effluent was analyzed using an online gas chromatograph with flame ionization detector (GC-FID) for OAand organic reaction products and using an on-line GC with thermal conductivity detector (GC-TCD) for analysis of non-condensable gases (CO and CO2). Alternatively, a quadrupole mass spectrometer (QMS) with an atmospheric-pressure gas inlet system was used for non-condensable gas analysis.WGS reaction experiments were conducted in the same apparatus using 0.5 or 1.0 g catalyst powder suspended between quartz wool plugs. Under the standard test conditions, the feed gas contained 1.25% CO (25 sccm, 5% CO/He), and deionized (DI) water was injected resulting in a H2O:CO molar ratio of unity. H2 and He flowrates (75 sccm total) were adjusted to give a feed composition of 0,10 or 75% H2. The DI water injection rate was increased to achieveH2O:CO ratios of 2 and 4.
