MALIC ACID AND KMNO4-BASED COMBINED AND MODIFIED COW DUNG BIOGAS RESIDUE HYDROCHAR PREPARATION METHOD

摘要

A malic acid and KMnO₄-based combined and modified cow dung biogas residue hydrochar preparation method, comprising: mixing a cow dung biogas residue with malic acid, and performing ultrasonic treatment to obtain a malic acid modified cow dung biogas residue; performing a hydrothermal reaction with KMnO₄ in a high-temperature high-pressure reactor to obtain a combined and modified cow dung biogas residue hydrochar material.
