With the rapid replacement and upgrading of electronic products worldwide, waste printed circuit boards (PCBs) have become one of the fastest-growing components of electronic waste. These discarded boards contain not only non-metallic materials such as resins and fiberglass, but also…

During industrial processes such as petrochemical production and oil/fat hydrogenation, hydrogenation catalysts gradually lose their activity after prolonged use and become spent catalysts. The nickel content in these spent catalysts can typically reach 6% to 20%, which is significantly higher…

In the fields of fine chemicals, pharmaceutical intermediates, pesticide raw materials, and oil-based material purification, water washing, alkali washing, and acid washing are critical processes that directly determine product purity and yield. For many years, traditional reactor static settling processes…

In the production fields of fine chemicals, pharmaceuticals, coatings, and new energy materials, glycol ether organic solvents (such as ethylene glycol ethers, propylene glycol ethers, isopropyl ether, and isopropanol) are widely used. However, these production processes generate large amounts of…

During the lithium extraction process from ores such as spodumene and lepidolite, lithium precipitation mother liquor is often regarded as “waste liquid” or a low-value by-product. However, hidden in this seemingly ordinary alkaline mother liquor are two rare alkali metals…

In the modern chemical industry, efficient and environmentally friendly material separation and purification technologies are key drivers of industrial upgrading. Especially for the recycling and reuse of important organic solvents such as benzene and xylene, the traditional batch reactor operation…
