Carbonization and Hydrogenation

Carbonization and Hydrogenation

Carbonization and hydrogenation are important processes used to refine lithium compounds in industries such as battery manufacturing, ceramics, and specialty glass. These methods help improve material purity to meet the demands of advanced applications. Among various purification techniques, the dissolution–precipitation method stands out as the most commonly used due to its efficiency and simplicity. Other options, including oxidation, solvent extraction, and ion exchange, may be selected depending on the characteristics of the raw material and the desired purity level.

Hebei Yanming provides integrated carbonization and hydrogenation systems designed to purify industrial-grade lithium carbonate and convert lithium hydroxide into high-purity or battery-grade lithium carbonate. The carbonation equipment we offer, ensures precise control over reaction conditions, improving lithium recovery rates and achieving the purity levels required by battery manufacturers and specialty chemical producers.
    1. Lithium Carbonate Carbonation System
    2. Lithium Carbonate Carbonation System High-purity lithium carbonate is widely used in the production of advanced cathode materials for lithium-ion batteries, as well as in the preparation of battery-grade lithium fluoride. In the optoelectronic field, it serves as a key raw material for producing lithium tantalate and lithium niobate. It’s also applied in specialty optical glass, magnetic materials, supercapacitors, and pharmaceutical products. View Details
    1. Lithium Hydroxide Carbonation System
    2. Lithium Hydroxide Carbonation System Carbonating lithium hydroxide is a clean and efficient way to produce lithium carbonate, as it doesn’t introduce unwanted impurity ions. However, traditional batch processes often face challenges such as clogged gas distributors in the carbonation column due to lithium carbonate crystal formation, low CO₂ utilization leading to higher production costs, and inconsistencies in product quality across batches. These systems also require significant manual operation, resulting in higher labor intensity and cost. View Details
