A study on the kinetics of the gas–liquid reaction between nitric oxide and [Fe(II)NTA]−
Iron nitrilotriacetic acid ([Fe(II)NTA]−) solution is able to absorb NO from flue gases. In this study, the kinetics of the gas–liquid reaction between NO and [Fe(II)NTA]− has been determined using a double stirred cell. The study indicates that the reaction between NO and [Fe(II)NTA]− is turned into gas film controlling as the [Fe(II)NTA]− concentration is over 0.03 mol L−1. The reaction rate between NO and [Fe(II)NTA]− is in proportion to the inlet nitric oxide concentration. 50°C is considered to be the best temperature for [Fe(II)NTA]− solution absorbing nitric oxide. The reaction rate between NO and [Fe(II)NTA]− decreases as pH drops below 5.5. The negative effect of pH may be reduced as the [Fe(II)NTA]− concentration increases. The reaction rate between NO and [Fe(II)NTA]− varies little in the pH range from 5.5 to 8.0. The kinetic equation for the gas–liquid reaction between NO and [Fe(II)NTA]− under the controlling of both liquid film and gas film has been obtained as follows:
期刊介绍：
The Canadian Journal of Chemical Engineering (CJChE) publishes original research articles, new theoretical interpretation or experimental findings and critical reviews in the science or industrial practice of chemical and biochemical processes. Preference is given to papers having a clearly indicated scope and applicability in any of the following areas: Fluid mechanics, heat and mass transfer, multiphase flows, separations processes, thermodynamics, process systems engineering, reactors and reaction kinetics, catalysis, interfacial phenomena, electrochemical phenomena, bioengineering, minerals processing and natural products and environmental and energy engineering. Papers that merely describe or present a conventional or routine analysis of existing processes will not be considered.
