Nitric Oxide Absorption From Flue Gas With Cumene Hydroperoxide Solution, Chung-Der Chen
Nitric Oxide Absorption From Flue Gas With Cumene Hydroperoxide Solution, Chung-Der Chen
Theses
The absorption of nitric oxide from gas streams with cumene hydroperoxide (CHP) in n-hexadecane (cetane) as the scrubbing solution was investigated. The efficiency of the scrubbing solution to remove nitric oxide was evaluated over the temperature range of 90 to 110°C, concentration range of 0.1 to 0.5M, and residence time of 12 to 80 seconds. The products were analyzed by gas chromatography (GC), Fourier transform infrared spectroscopy (FTIR), and ion chromatography (IC). The goal of this research was to determine the NO removing efficiency of cumene hydroperoxide solution, a relatively inexpensive tertiary organic hydroperoxide. Also, a possible reaction mechanism for …
Selective No Absorption From Gas Streams With Tertiary Organic Hydroperoxide Solutions, Huihong Ao
Selective No Absorption From Gas Streams With Tertiary Organic Hydroperoxide Solutions, Huihong Ao
Theses
The selective removal of nitric oxide from gas streams was investigated using 3,6-dimethyl-3-octyl hydroperoxide, p-menthane hydroperoxide, pinane hydroperoxide, and cumene hydroperoxide in solutions of n-hexadecane (cetane). The influence of different parameters such as temperature, gas stream flow rate (or residence time), and concentration of hydroperoxide compounds on efficiency of NO removal was evaluated. The basis of this research was to duplicate atmospheric reactions between hydroperoxides and NO in order to produce NO2. We succeeded in removing NO from gas streams, but failed to produce NO2. NO reacted with the hydroperoxides to produce nitrates. These nitrates are …
