无水硫化钠生产工艺实现重大突破

国内传统无水硫化钠生产工艺繁琐，采用工业无水硫化钠或晶体硫化钠经多道脱水精制工序，存在能耗高、成本高、产品质量不稳定等痛点，长期制约高端新材料产业发展。我司重磅实现技术革新，独创稀相流态化氢气还原一步法生产工艺，一举攻克行业核心难题，填补了我国无水硫化钠规模化、连续化量产的技术空白。
新工艺可稳定产出高纯无水硫化钠，品质优异，既能赋能聚苯硫醚（PPS）企业升级产品、打破国外高端PPS产品垄断，也能为固态电池产业化、爆发式增长提供核心高纯原料支撑。同时，该技术可利用高炉煤气、废硫酸钠制备工业级硫化钠，大幅降低能耗，削减三废排放，践行资源循环与绿色低碳理念，有望彻底颠覆国内硫化钠高耗、高排的传统生产格局。

Major Breakthrough in Anhydrous Sodium Sulfide Production Technology
The traditional production process of anhydrous sodium sulfide is complicated. Adopting industrial or crystalline sodium sulfide as raw materials requires multiple dehydration and refining procedures, which features high energy consumption, high production costs and unstable product quality. These long-standing drawbacks have severely restricted the development of the high-end new materials industry. Our company has achieved a groundbreaking technological innovation by developing the one-step dilute-phase fluidized hydrogen reduction process, which thoroughly solves core industrial problems and fills the domestic gap in the large-scale and continuous production of anhydrous sodium sulfide.
This innovative process enables the stable production of high-purity anhydrous sodium sulfide with superior quality. It empowers polyphenylene sulfide (PPS) manufacturers to upgrade product quality and break the foreign monopoly on high-end PPS products. Additionally, it provides high-purity core raw materials to support the industrialization and explosive growth of solid-state batteries. Furthermore, the technology can produce industrial-grade sodium sulfide using blast furnace gas and waste sodium sulfate, significantly reducing energy consumption and three-waste emissions. Adhering to the concepts of resource recycling and green low-carbon development, it is poised to subvert the traditional high-consumption and high-emission production pattern of sodium sulfide industry.

电解硫酸钠制硫化钠联产硫酸清洁环保新工艺研究

我国是世界硫化钠主要生产国，现主要生产方式仍然采用的是高碳、高污染排放的煤炭还原硫酸钠生产硫化钠的方法；近些年，国家清洁能源（太阳能、风能、 水能、核聚变能等）在迅猛发展，硫化钠的生产已具备电解法清洁环保生产（无二氧化碳、二氧化硫、硫化氢、氮氧化物排放）条件。本文介绍了电解硫酸钠制硫化钠联产硫酸、电解氯化钠产出的氢氧化钠生产硫化钠联产硫代硫酸钠或亚硫酸钠的方法，以推动我国硫化钠生产向清洁环保方面快速发展。
