Description
본 발명은 산업 폐기물인 폐촉매를 재활용하기 위하여 개발된 건설용 자재 조성물 및 이를 이용한 건설용 자재 제조방법에 관한 것이다.The present invention relates to a construction material composition developed to recycle waste catalyst, which is industrial waste, and a construction material manufacturing method using the same.
일반적으로 폐촉매는 촉매로 사용되고 그 기능이 떨어지거나, 수명이 다 되어 촉매로써 기능을 발휘하지 못하여 폐기될 때 발생하는 물질로서, 석유정제, 석유화학, 식품 및 제약, 고분자 중합, 무기화학, 및 환경산업 등 다양한 산업에서 폐촉매가 발생된다.In general, a waste catalyst is a material generated when it is used as a catalyst and its function is deteriorated or it is not functional as a catalyst due to the end of its life and is discarded. Waste catalysts are generated in various industries such as the environmental industry.
이러한 폐촉매는 유가성의 희금속 및 여러 종류의 금속들을 포함하고 있어 재활용 가치가 높은 폐기물이다. 재활용 방법에는 촉매표면의 흡착물질을 제거하여 촉매로써 재사용하는 방법과 고순도의 유가금속으로 회수하는 방법, 촉매 및 철강원료로 사용되는 방법 등으로 재활용이 가능하다.These waste catalysts are wastes with high recycling value because they contain valuable rare metals and various types of metals. Recycling is possible by removing the adsorbed material on the catalyst surface and reusing it as a catalyst, recovering it as a valuable metal of high purity, and using it as a catalyst and steel raw material.
그러나, 석유화학 산업에서 발생되는 폐촉매는 산업폐기물로서 발생업체에서 보관, 처리하거나 폐기물 처리업체에 위탁하여 처리한다. 그러나, 아직도 백금족의 제련에 대한 국내기술 수준이 낮아 폐촉매의 효과적인 재활용이 이루어지지 않고 있다.However, waste catalysts generated in the petrochemical industry are industrial wastes that are stored and treated by the generator or entrusted to a waste treatment company. However, the level of domestic technology for platinum group smelting is still low, and effective recycling of waste catalyst has not been achieved.
그리하여, 폐촉매를 효과적으로 재활용하기 위한 방안으로서, 폐촉매를 파쇄하여 시멘트 보강재나 콘크리트 혼화재의 원료로 사용하는 방안이 제안되었다. 그러나, 폐촉매를 활용한 건설용 자재의 경우 경량 골재 및 중량 골재 등에서 요구하는 압축강도를 발현할 수 없어 문제가 되고 있다.Therefore, as a method for effectively recycling the waste catalyst, a method of crushing the waste catalyst and using it as a raw material for cement reinforcing materials or concrete admixtures has been proposed. However, in the case of construction materials using waste catalysts, there is a problem in that they cannot express the compressive strength required for lightweight aggregates and heavy aggregates.
따라서, 경량 골재 및 중량 골재 등에서 요구하는 압축강도를 발현할 수 있도록 폐촉매를 이용한 건설용 자재에 대한 연구 개발이 시급한 실정이다.Therefore, there is an urgent need to research and develop materials for construction using waste catalysts in order to express the compressive strength required for lightweight aggregates and heavy aggregates.
본 발명의 목적은 경량 골재 및 중량 골재 등에서 요구하는 압축강도를 발현함과 동시에 폐촉매를 재활용하여 경제성을 수반하는 폐촉매를 이용한 건설용 자재 조성물 및 폐촉매를 이용한 건설용 자재 제조방법을 제공하는 데에 있다.An object of the present invention is to provide a construction material composition using a waste catalyst and a method for manufacturing construction materials using a waste catalyst, which is accompanied by economic feasibility by recycling the waste catalyst while expressing the compressive strength required for lightweight aggregate and heavy aggregate, etc. is in
