Technology of producing bio-ethanol

摘要

The present invention relates to the field of producing a bio-ethanol what could be used as fuel or fuel additives for internal combustion engines. For the purpose of excluding environmental dangerous substances from technological process as well as for the purpose of decreasing energy costs and cost price. The intention is achieved by passing aqueous ethanol mixtures through carbon molecular sieves in the fractionating column and following regeneration of said sieves using water-desorbents. The basic stage of producing bio-ethanol contains using carbon molecular sieves as water-adsorbents and spirituous solution of anhydrous calcium chloride as water-desorbents. The mentioned invention may be used in present as well as in new factories provided for production of bio-ethanol as fuel for internal combustion engines.
