Though not a new idea, use of bioethanol as a platform for production of chemicals or other fuels is re-emerging as a significant strategy among chemical and energy industry players, often allied with the owners of the carbohydrate feedstocks/bioethanol production. Several projects are underway and others are being studied to convert Brazilian sugarcane ethanol to ethylene for polymers production. Others are proposed for India and elsewhere in Asia . These will use one or another version of long-commercialized, simple catalytic dehydration technology. Others are considering routes to condense ethanol to n-butanol and higher alcohols, or for direct fermentation of cane sugars to other hydrocarbon monomers and fuels, leveraging bioethanol know-how and facilities. This paper will identify and analyze the technologies and economics of these broad cases and the players comprising these developments.
