Production of Formaldehyde from CH4 and H2S (Technology #: 020102-01)
A method wherein a sour natural gas stream can be treated to produce primarily carbon monoxide from methane, and the carbon monoxide and hydrogensulfide are reacted to produce methyl mercaptans, (primarily methanethiol (CH.sub.3 SH) and a small amount of dimethyl sulfide (CH.sub.3 SCH.sub.3)). The methyl mercaptans preferably are passed in contact...
