Shell正在开发一种以CO2为原料、环境友好且成本低廉的丙二醇和聚碳酸酯(PC)生产工艺。该工艺以CO2、苯酚和环氧丙烷为原料,生成物是丙二醇(PG)和碳酸二苯酯(DPC,DPC是一种可以取代光气的PC生产原料)。Shell拟向PC生产商出售DPC产品。Shell称,“该新工艺不仅比传统的PC生产工艺清洁,且生产成本也相对较低。无论什么样的公司,只要能够找到一种相对便宜的DPC生产方法,就意味着该公司能够在
Shell is developing a CO2-based propylene glycol and polycarbonate (PC) production process that is environmentally friendly and inexpensive. The process to CO2, phenol and propylene oxide as raw materials, the resulting product is propylene glycol (PG) and diphenyl carbonate (DPC, DPC is a PC that can replace phosgene production of raw materials). Shell intends to sell PC makers DPC products. Shell said, ”The new process is not only cleaner than the traditional PC manufacturing process, and its production costs are relatively low. No matter what kind of company, as long as we can find a relatively cheap DPC production method, it means that the company is able to
