METHOD FOR UTILIZING EXHAUST GAS PHOSPHORIC ACID RECOVERED FROM CARBONIZATION AND ACTIVATION REACTION OF PHOSPHORIC ACID PROCESSED ACTIVE CARBON

摘要

Provided is a method for recovering phosphoric acid from the exhaust gas of carbonization and activation reaction of phosphoric acid processed active carbon, characterized in that: collecting the exhaust gas liquid containing phosphoric acid, uniformly mixing with an active carbon raw material, drying, adsorbing the exhaust gas liquid containing phosphoric acid onto the active carbon raw material, and using as the raw material to manufacture the phosphoric acid processed active carbon. The method enables exhaust gas phosphoric acid recovery of high efficiency and low production costs, thereby providing substantial economic benefit.
