Abstract

본 발명은 활성탄소의 제조방법에 관한 것으로, 펄프잔사 또는 파쇄폐지를 열경화성 고분자 수지와 혼합하여 경화시켜 탄소화하고 이를 다시 수산화칼륨과 혼합하고 불활성 분위기 하에서 적정온도 및 시간으로 활성화 처리하므로서, 수율 및 비표면적이 우수한 활성탄소의 제조방법을 제공하고자 하는데, 그 목적이 있다.The present invention relates to a method for producing activated carbon, wherein pulp residue or shredded paper is mixed with a thermosetting polymer resin, cured, carbonized, and then mixed with potassium hydroxide and activated at a proper temperature and time under an inert atmosphere, thereby yielding An object of the present invention is to provide a method for producing activated carbon having an excellent surface area.

상기한 목적을 달성하기 위한 본 발명은 파쇄폐지 및 펄프잔사를 원료로 사용하여 활성탄소를 제조하는 방법에 있어서, 단독 또는 복합의 파쇄폐지 및 펄프잔사와 열경화성 수지를 75 : 25 - 50 : 50의 중량비 범위로 혼합하고 충분히 경화시켜 성형체를 제조한 후 불활성 분위기하에서 500℃이상의 온도로 열처리하여 탄화물을 제조한 다음, 상기 제조된 탄화물과 수산화칼륨을 20 : 80 - 33 : 67의 중량비 범위로 혼합하여 불활성 분위기 하에서 500-900℃의 온도범위로 120분 이내에 열처리하는 것을 포함하여 이루어지는 폐지 및 펄프잔사를 이용한 활성탄소 제조방법에 관한 것을 그 요지로 한다.In order to achieve the above object, the present invention provides a method for producing activated carbon using shredded waste paper and pulp residue as raw materials, wherein the shredded waste paper and pulp residue and thermosetting resin of 75 or 25-50: 50 are used alone or in combination. After mixing in a weight ratio and sufficiently hardening to prepare a molded product, and heat treatment at a temperature of 500 ℃ or more in an inert atmosphere to prepare a carbide, then mixing the prepared carbide and potassium hydroxide in a weight ratio range of 20: 80-33: 67 The gist of the present invention relates to a method for producing activated carbon using waste paper and pulp residue comprising heat treatment within a temperature range of 500-900 ° C. within 120 minutes in an inert atmosphere.
