Zusammenfassung:	The present invention relates to a gasifier capable of continuously regenerating carbon-based additive and a method for producing syngas using the same to provide a technology for regenerating additive used for removing tar while removing tar generated in the production of syngas. According to an embodiment of the present invention, the gasifier comprises: a fluidizer bed gasification unit generating syngas by thermally decomposing fuel and water introduced into the inside by the heated fluidized sand; a tar removal unit formed on the upper part of the fluidized bed gasification unit, receiving syngas to remove tar from syngas using an additive for reducing tar inside; and a gas flow unit receiving syngas from the fluidized bed gasification unit to discharge the syngas into the tar removal unit. 본 발명의 일 실시 예는 합성가스의 제조에서 생성되는 타르를 제거함과 동시에 타르 제거에 이용되는 첨가제를 재생시키는 기술을 제공한다. 본 발명의 실시 예에 따른 탄소 기반 첨가제 연속 재생식 가스화 장치는, 내부로 투입된 연료와 물을 내부에 수용되어 가열된 유동사에 의해 열분해시켜 합성가스를 생성시키는 유동층가스화부; 유동층가스화부의 상부에 형성되고, 합성가스를 전달받으며, 내부에서 타르 저감용 첨가제를 이용하여 합성가스 내 타르를 제거하는 타르제거부; 및 유동층가스화부로부터 합성가스를 전달받아 타르제거부의 내부로 배출시키는 가스유동부;를 포함한다.
