传统的无机化学品均是采用独自的矿产资源分别进行加工,生产资源与能源未能实现循环经济再利用、循环和分级利用的生产原则,全生命周期能源消耗无效率高。要实现碳达峰、碳中和,满足新产业的需要,就需要开发无机盐化工资源性耦合低碳的新技术新工艺。在钛、磷、硫资源耦合生产钛白粉与湿法磷酸盐先进工艺技术模式的基础上,以储能材料磷酸铁锂为例,提出将钛铁矿-磷灰石矿-锂灰石矿三矿耦合,按“元素经济”的绿色工艺技术路线生产储能材料磷酸铁及磷酸铁锂产品,论述了磷酸铁锂三元素上游磷化工、钛化工、锂化工面临节能减碳的挑战与耦合新技术创新的机遇及市场发展前景。

Traditional inorganic chemicals are processed separately with independent mineral resources.The production resources and energy fail to follow the production principle of circular economy recycling,recycling and graded utilization,and the efficiency of energy consumption in the whole life cycle is no high.In order to achieve carbon peaking,carbon neutralization and meet the needs of new industries,it is necessary to develop new technologies and processes of inorganic salt chemical resources coupling low-carbon.On the basis of the advanced process technology mode of coupling titanium dioxide and wet process phosphate with titanium,phosphorus and sulfur resources,taking the energy storage material lithium iron phosphate as an example,it was proposed to couple ilmenite,apatite and limonite and produce energy storage materials of iron phosphate and lithium iron phosphate products according to the green process technology route of “element economy”.The challenges of energy conservation and carbon reduction faced by phosphorus chemical industry,titanium chemical industry and lithium chemical industry in the upstream of lithium iron phosphate three elements,as well as the opportunities and market development prospects of coupling new technology innovation were discussed.
