University of Massachusetts Amherst Paul J. Dauenhauer led research team found that the new method, a production of biomass plastic, low-cost, most of the biomass as a raw material can be to 75% the yield of xylene (biomass plastic raw materials), the study results were published in the journal of the American Chemical Society (ACS), the “catalyst”. Xylene was used to produce PET (polyethylene terephthalate) plastic, the scope of uses including many products, such as carbonated beverage bottles, food packaging, synthetic clothing, and even auto parts. At present, the plastics industry is the oil as raw material to produce para-xylene; new method is a renewable way of biomass raw materials of the chemical, thereby producing marked with the triangular recycling logo “1 #” plastic products. This method uses molecular sieve catalyst, through the three-step reaction can be conversion of glucose to para-xylene in the high-temperature bioreactor. Nano-structure of the catalyst has a great effect on the biological response, the catalyst of this particular design is the key to success, it has been a series of optimization improvements, used to promote the reaction of p-xylene, and improve yield. This is a major breakthrough, because the other method for the production of renewable xylene, or expensive (eg fermentation), or low reaction efficiency, low production yield. In the future, the method can be further optimized to improve the yield of para-xylene and reduce costs. This finding is part of the innovative energy catalytic center (CCEI), a breakthrough research to the manufacture of biofuels and chemicals from lignocellulosic biomass program
