Invitation to present
"The Novel SupraYield® Process for Efficient Production Of Furfural
From Renewable Resources" (December 2005).
Keywords: furfural; chemurgy;
Abstract: Furfural is produced by the liquid phase acid catalytic
dehydration of pentose, which is obtained by liquid phase acid
catalytic hydrolysis of pentosan polymers in woody vegetable
matter. Current industrial furfural processes strip this
furfural from the substrate using live steam. The patented (IFT 2001)
SupraYield® process described here overcomes problems of energy
inefficiency, yield-loss reactions, product purity and effluent
generation by using adiabatic flash distillation in the reactor.
The process is described, together with the theoretical considerations
and experimental work that made it marketable.

Our furfural expert is back and offers you what he calls “a
story against all odds”.
Current industrial processes yield only about half as much
furfural as expected from analytical procedures. Why is this, and what
must be done to boost industrial yields to the “analytical” level?
The by-products diacetyl and 2,3-pentanedione are produced in
sizable quantities—and this is a good thing.
