据安迅思休斯敦4月5日消息，美国Origin公司与AECI SANS Technical Fibres宣布扩大合作关系来开发Origin公司将生物质转化为对二甲苯(PX)的工艺。
该合作伙伴关系包括一项购买碳排放为负值的聚对苯二甲酸乙二醇酯(PET)的协议，PET将用于广泛的终端产品，包括服装、内衣、鞋类和汽车缝纫线应用。
SANS是Origin的战略投资者AECI的全资子公司。该公司生产用于服装和汽车的线。
两家公司还将合作开发和商业化基于Origin生产可再生PX工艺的新产品。
Origin公司的工艺可以将木质生物质转化为可用于制造可再生PX的中间体。这个过程的碳排放是负值。
其他公司也曾尝试生产可再生PX，但都以失败告终。可再生PX不仅有助于抵消温室气体排放，而且提供了一种成本上具有竞争力的替代传统的PX来生产PET。
然后，PX被用来生产精对苯二甲酸(PTA)，PTA与乙二醇(MEG)结合生成PET。
如果成功，Origin相信这种碳排放为负值的材料将帮助革新广泛的终端产品，包括服装、纺织品、塑料、包装、汽车零部件、轮胎、地毯和玩具。
该公司估计，其技术的市场价值约为1万亿美元。

US Origin and SANS expand partnership to develop renewable PX from biomass
US Origin and AECI SANS Technical Fibres announced an expansion of a partnership to develop Origin’s process to convert biomass into paraxylene (PX).
The partnership includes an agreement to buy carbon-negative polyethylene terephthalate (PET) to be used in a wide array of end products, including clothing, intimate apparel, footwear, and automotive sewing thread applications.
SANS is a wholly owned subsidiary of AECI, a strategic investor in Origin. The company makes thread for apparel and automotive applications.
The two companies will also work together to develop and commercialise new products based on Origin’s process to make renewable PX.
Origin’s process takes woody biomass and converts it into an intermediate that can be used to make renewable PX. The process is carbon negative.
Other companies have attempted and failed to make renewable PX. The feedstock would not only help offset greenhouse gas emissions, but offer a cost-competitive alternative to traditional PX to make PET.
PX is then used to make purified terephthalic acid (PTA), which is combined to monoethylene glycol (MEG) to make PET.
If successful, Origin believes its carbon-negative materials will help revolutionise a wide range of end products, including clothing, textiles, plastics, packaging, car parts, tyres, carpeting and toys.
The company estimates that the market for their technology could be worth about $1tr.
