Ready for plastic and polyesters - and fuel - that grows on trees?
It has been an elusive goal for the legion of
chemists trying to pull it off: Replace crude oil as the root source for
plastic, fuels and scores of other industrial and household
chemicals.
It has been an elusive goal for the legion of chemists trying to pull it off: Replace crude oil as the root source for plastic, fuels and scores of other industrial and household chemicals with inexpensive, nonpolluting renewable plant matter.
Scientists took a giant step closer to the biorefinery today, reporting in the journal Science that they have directly converted sugars ubiquitous in nature to an alternative source for those products that make oil so valuable, with very little of the residual impurities that have made the quest so daunting.
"What we have done that no one else has been able to do is convert glucose directly in high yields to a primary building block for fuel and polyesters,” said Z. Conrad Zhang, senior author who led the research and a scientist with the PNNL-based Institute for Interfacial Catalysis, or IIC.
That building block is called HMF, which stands for hydroxymethylfurfural. It is a chemical derived from carbohydrates such as glucose and fructose and is viewed as a promising surrogate for petroleum-based chemicals.
As Zhang put it, “The opportunities are endless and the chemistry is starting to get interesting.”
When we get past the dimwits who think science and technology is something inherently satanic, something gets accomplished.
