Biomass Gasification (2008 Program)

Various approaches for biomass gasification are assessed including pyrolysis, staged gasification, and indirect gasification. Associated issues such as biomass availability and downstream syngas-based technologies, such as fermentation, mixed alcohols synthesis and FT syntheses are presented. A case study comparing the production economics of n-butanol via biomass gasification versus conventional propylene oxo synthesis is given.

Glycerin Conversion to Propylene Glycol (2008 Program)

The chemistry and technology for converting crude biodiesel-derived glycerin to propylene glycol are assessed. Process technologies developed by Davy, UOP and Senergy are reviewed and the COP economics for this conversion is compared to conventional propylene oxide hydrolysis. Market information for glycerin and propylene glycol is included.

"Green" Polyethylene (2008 Program)

Conversion costs of sugar-cane and corn-based ethanol to ethylene and then to polyethylene are compared to the costs of polyethylene made from ethylene produced in an ethane cracker.  The costs of biomass gasification to syngas to methanol to ethylene (via MTO) and finally to polyethylene are compared to the above routes.
