The yeasts with high alcohol concentration restrains combined with zymomonas mobilis by the ED metabolism are bred, the process conditions are optimized and the equipments are ameliorated to produce bioalcohol from potatoes with higher purity and inversion ratio. Therewith, the separation procedures of bioalcohol can be decreased.
Based on the principle of energy conversion, the mechanism of ethylene synthesis by catalytic dehydration of bioalcohol is investigated and the catalyst is designed to search the process of ethylene synthesis from bioalcohol under lower temperature.
The industrial reactor on thousand tons scale for ethylene synthesis by catalytic dehydration of bioalcohol is designed and assembled. The process parameters such as reactor configuration, heat supply quomodo, raw material ratio, catalyst contact mode, are optimized.

The research contents on the three key technologies for the industrialization of bio-ethylene come down to as below: the yeasts with high alcohol concentration restrains are bred to obtain bio-alcohol from potatoes with higher purity, the mechanism of ethylene synthesis by catalytic dehydration of bio-alcohol is investigated to obtain the catalytic process of ethylene synthesis from bio-alcohol under lower temperature, The industrial reactor on thousand ton scale for ethylene synthesis by catalytic dehydration of bio-alcohol is designed and assembled to obtain the optimized reactor configuration and process parameters. The technologies can be provided to the industrialization of bio-ethylene on a large scale at lower cost to profit bio-ethylene competitive in the market.
