Abstract
Hydrogen and carbon dioxide are produced by activating a mixture of carbon monoxide and water with monochromatic light. Preferably, a unidirectional stream of steam activated with a laser at 5400 cm..sup.-1 collides with a carbon monoxide stream to effect the reaction. The carbon dioxide can then be reacted with water to produce formaldehyde. Ketene and water are produced by exposing the formaldehyde to ultraviolet light.
