20250177949. Resin Substrate-based Iron Oxyhydroxide Desulfurizing Agent Preparation Method Theref (MINGSHUO ENVIRONMENT TECHNOLOGY GROUP ., .)
RESIN SUBSTRATE-BASED IRON OXYHYDROXIDE DESULFURIZING AGENT AND PREPARATION METHOD THEREFOR
Abstract: disclosed are a resin substrate-based iron oxyhydroxide desulfurizing agent and a preparation method therefor, falling within the technical field of gas purification and treatment. in the present disclosure, sodium percarbonate is used as a raw material to prepare iron oxyhydroxide. sodium percarbonate serves both as an alkaline precipitant and as an oxidant. p-aminophenol and formaldehyde are subjected to condensation polymerization to form linear phenolic resin, which is then modified with terephthalyl alcohol to connect into a cross-linked network structure resin. the resin is used as a substrate to obtain the resin substrate-based iron oxyhydroxide desulfurizing agent. the preparation method of the present disclosure is simple and achieves a larger sulfur capacity and desulfurization efficiency, making it suitable for the removal of hydrogen sulfide from waste gas.
