Abstract
The invention comprises a recirculatory process for producing hydrocarbons and oxygen in which sulphur dioxide is reacted with iodine and water to form a hydrogen polyiode or a hydrate thereof and sulphuric acid, the sulphuric acid is separated and thermally decomposed to form water sulphur dioxide and oxygen, the polyiodide or its hydrate is decomposed to form iodine and gaseous hydrogen iodide which is concurrently or separately reacted with a carbon oxide or mixture of carbon oxides to form hydrocarbons especially methane and water, the hydrocarbons and water being removed from the system and the remaining reaction products recirculated.
