Biomass to Ethylene (B2)

Executive Summary

The objective of this process is to create ethanol from biomass and then to convert this bio-ethanol to ethylene. The overall process feed is corn stover, which is degraded into simple sugars and fermented with the organism Zymomonas Mobilis to create ethanol. The ethanol is then converted to ethylene using packed bed reactors with an aluminum oxide on gamma-alumina catalyst. The working plant capacity is 2000 MT/day of corn stover. Refer to Appendix I for a overall process flow diagram.

The secondary objective of this process is to evaluate the feasibility of this process by considering economics and safety. All of these items will be discussed in the following sections.
