Aqueous Phase Reformer
Our aqueous phase reformer set-up consistes of two ISCO syringe pumps operating in parallel pumping reactants through a stainless steel reactor containing a powder catalyst. The reaction can occur at high pressure and moderate temperatures in either the gas or liquid phases. The reactor products are sent to a flash evaporator, where liquid products can be sampled for analysis in a gas chromatograph and the gaseous products are swept with nitrogen to a micro-gas chromatograph.
High Temperature Oxidation and Water Gas Shift Reactor
Our oxidation/shift reactor consists of several thermal gas flow meters for the introduction of gases into the reactor. A fuel injector with a pressurized tank is used to feed liquids separately into the reactor. Structured monoliths are secured inside the quartz reactor. Product gases are sampled and quantified in an Agilent 7890 gas chromatograph with multiple columns and a thermal conductivity detector.
Our micro-gas chromatograph has three channels for measuring the concentrations of hydrogen, carbon dioxide, and other (nitrogen, carbon monoxide, methane) gases leaving our aqueous phase reformer.
Our 7890 gas chromatograph contains two inlets, a switching/isolation valve, and thermal conductivity or flame ionization detectors. Currently, we use this GC to measure the concentration of products leaving our oxidation/shift reactors
Our 6890 gas chromatograph - mass spectrometer contains two inlets with one connected to a 100 sample auto-sampler, two switching/isolation valves, and three detectors (FID, TCD, MS). This instrument is currently used to measure concentrations of liquid products from our aqueous phase reformer as well as from our pyrolysis oils.
We use an AutoChem II instrument to chemically characterize our catalysts. Our instrument is capable of running single point BET, H2/CO chemisorption, NH3-TPD, TPR, and TPO.
Our plasma reactor consists of a mechanical vacuum pump and radio frequency generator. A removable 250 mL trypsynizing flask with a joint fitting holds the powder undergoing plasma modification. The system is capable of operating under any gaseous atmosphere one desires.
Our lab has two tube furnaces: one is a horizontal furnace capable of housing a ~1.5 inch diameter tube and the other is arranged vertically capable of housing a ~3 inch diameter tube.
