AI Technical Summary

Technical Problem

Existing waste sulfuric acid treatment processes suffer from high processing costs, serious resource waste, significant environmental risks, high equipment investment, and high energy consumption. Furthermore, traditional methods are difficult to effectively recover high-value-added products.

Method used

A process for preparing microporous carbon from waste sulfuric acid includes a hydrated precipitated carbon reaction stage, an aged microporous carbon reaction stage, a separation stage, and tail gas treatment. By controlling the temperature and concentration, microporous carbon with multiple active sites is prepared, and the purified acid is used to prepare sulfates. The microporous carbon is used as fuel and an adsorbent for organic matter.

Benefits of technology

It achieves resource reduction, recycling, and energy reduction, lowers processing costs, produces high-value-added products, reduces environmental pollution risks, and does not require investment in complex equipment.
