A program to study CH reactions relevant to combustion/gasification processes
The goal of the proposed work has been to study a small, but important family of CH reactions of interest in combustion-related systems; namely CH + N{sub 2}, H{sub 2}, O{sub 2}, NO, and N{sub 2}O. Until now, these reactions have been studied almost exclusively by IR or UV flash photolysis at moderate temperatures, and little quantitative information about product species has been obtained. The explicit objectives of the present effort were: (1) to develop and characterize a new CW source of CH radicals suitable for use in a fast-flow reactor, (2) to use this source to measure rate constants for several key CH reactions as a function of temperature, and (3) to detect the product channels of these reactions wherever possible. Our accomplishments include: the successful development of a chemical source of CH radicals; the measurement of eight rate constants at 300 K (which agree with previously reported values where available); the detection of OH produced by the CH + NO and O{sub 2} reactions; the completion of a thorough study of isotopic exchange in the products of the reaction CH + CO; and, finally, the taking of the first steps to extending this work to higher temperatures.
