Abstract: A feedstock gas, such as natural gas, is introduced into a mixing chamber. A combustible gas is introduced into a combustion chamber, for example simultaneously to the introduction of the feedstock gas. Thereafter, the combustible gas is ignited so as to cause the combustible gas to flow into the mixing chamber via one or more fluid flow paths between the combustion chamber and the mixing chamber, and to mix with the feedstock gas. The mixing of the combustible gas with the feedstock gas causes one or more products to be produced.
