2021year10month 27Day , Yuxin Energy Technology Co., Ltd. (Yuxin Co., Ltd.) announced that due to the current domestic development trend of degradable plastics and the impact of the double carbon policy, in order to meet the company’s carbon four industrial chain maleic anhydride development needs, the original light hydrocarbon comprehensive utilization project The first phase (one) is planned to be adjusted to the first phase of the light hydrocarbon comprehensive utilization project. After the adjustment, Yuxin will add more in the future9The production capacity of 10,000 tons of maleic anhydride will be increased at the same time span>1610,000 tonsBDOProduction capacity.
In the announcement, it is mentioned that due to the influence of the national policy on degradable plastics and double carbon, planning in recent years PBAT/PBScapacity exceeded1500Ten thousand tons, for raw materialsBDOThe demand has increased significantly. However, it is produced by the domestic mainstream alkyne aldehyde methodBDODue to the influence of environmental protection, energy consumption, raw materials and other aspects, there will be certain difficulties in the implementation of future projects, so the maleic anhydride esterification hydrogenation methodBDO is more worthy of attention.
Today, the editor will help you sort it outBDO Several productions process and its pros and cons.
At present, alkyne aldehyde method is the mainstream in ChinaBDOProduction process, according to the statistics of Tiantian Chemical Network, 2020Year of ChinaBDOeffective capacity227.910,000 tons/year (excluding maleic anhydride method), of which Alkyne aldehyde method (207.9Ten thousand tons/ year), propylene alcohol method (20Ten thousand tons/year). Due to the long-term deficit of the maleic anhydride method, all production capacity has been shut down (2020The annual production capacity of maleic anhydride method is26.8 tons).
With the impact of various national policies in the future, I believeBDOManufacturing companies will choose suitable production processes according to their own conditions. At that time, domestic alkyne aldehyde productionBDOThe phenomenon of technology dominance by one family may no longer exist.
