May I ask about humic acid production?
Thread Content
A classmate wants to start a factory to produce humic acid. I think it’s a useful product, but I’ve never been exposed to it before. Could you tell me what the production process for humic acid is?
1. Sodium humate is produced by heating peat, lignite, and weathered coal together with sodium hydroxide and water. Humic acid is formed through the reaction of acidic functional groups such as hydroxyl groups and phenolic groups in the humic acid structure with sodium hydroxide. Sodium humate fertilizer is in the form of black, shiny particles or powder; it is soluble in water, slightly alkaline, and its composition meets the required standards. According to ZBC21005—87, on a dry basis: humic acid > 40%, moisture
The key is to determine what purpose the humic acid you produce is intended for. The process mentioned above can only be used to produce fertilizer-grade humic acid; to obtain a higher quality product, it is necessary to make improvements to the methods used, or to carry out further purification steps.................
If you want to produce high-quality humic acid products, it’s quite complicated; boilers and drying equipment are necessary.
