Analysis Of Acetol And Guaiacol

The schematic diagram presented in Figure 1.1 illustrates the experimental rig used for the kinetic analysis of reactive flash volatilization (RFV) of acetol and guaiacol. The flow rates of oxygen and nitrogen gases were regulated using mass flow controllers (the type and serial number). Water, on the other hand, was delivered to an evaporator by a high-performance liquid chromatography pump (Agilent) at rates between 0.06 to 0.17 ml/min. The evaporator set at a temperature of 180C allowed to ensure water was in vapor form before entering the reactor. Furthermore, the transport of the water vapor and liquid organic feed was assisted by the nitrogen gas that flowed through the same pipe. The syringe pump used for the organic feed injection was automatically controlled by a computer program according to set values. Because of the high temperatures encountered at the inlet of the reactor, the liquid organic feed was converted to gas before it reached the catalyst bed. A pressure gauge mounted at the mixing point of the reactant gases was used to monitor the pressure within the reactor.

The gaseous product downstream of the air-cooled condenser was sent to gas chromatography (GC) for analysis while the liquid samples were analysed using a high-performance liquid chromatography (HPLC). For the first few experimental runs, the gaseous stream leaving the condenser was directed to go through a bubbling tube filled with water to examine the presence of any more condensable gases. The analysis procedures for the gas and liquid samples will be discussed in detail in Section
