摘要： A method for processing of expired solid rocket propellant containing ammonium perchlorate, powdered aluminium, and a rubber-based binder for the purpose of recycling ammonium perchlorate, the method comprising: a) wet disintegration of solid propellant in a solution to produce a suspension of solid substances; b) leaching of the suspension of solid substances at an increased temperature in a leaching solution to produce an ammonium perchlorate solution, the leaching solution including at least one of water and unsaturated ammonium perchlorate and containing added inert material based on at least one of porous carbon, diatomaceous earth and a polymer; c) wherein the use of the inert material during the leaching process increases de-agglomeration and decreases re-agglomeration of solid substances of the suspension of solid substances; d) separation of the ammonium perchlorate solution from the suspension of solid substances, the separated ammonium perchlorate solution also containing at least some of the inert material; e) refining of the separated ammonium perchlorate solution from step d) at an increased temperature; f) separation of the at least some of the inert material from the separated ammonium perchlorate solution to produce recycled ammonium perchlorate; g) crystallization of the recycled ammonium perchlorate.
