Claims (1)
예열된 중질유와 산화철 분말의 혼합물을 반응기 상단에서 0.01-0.02㎝방울로 사출하고 낙하시키면서 상승하는 기류에 의하여 가열할 때에 발생하는 휘발분을 회수하고 20％이상의 중질유의 고정탄소로 피복된 산화철 입자를, 반응기 중단에서 공급되는 공기로 연소한 1,000-1,400℃의 연소기류에 의하여 1-10sec동안에 환원시켜서 탄소와 혼합된 금속철을 만들고 반응기 하단에 예열된 공기 또는 농도 40％이상의 산소를 공급하여 나머지 탄소를 연소시키는 동시에 금속철을 용해시키는 것을 특징으로 하는 중질유 열분해 및 직접 환원 제철 방법.Injecting a mixture of preheated heavy oil and iron oxide powder into 0.01-0.02 cm droplets from the top of the reactor and recovering the volatiles generated when heated by the rising air flow, and the iron oxide particles coated with 20% or more of heavy oil fixed carbon, It is reduced for 1-10 sec by the combustion gas of 1,000-1,400 ° C combusted with air supplied from the reactor suspension to make metal iron mixed with carbon, and the remaining carbon is supplied by supplying preheated air or oxygen of 40% or more at the bottom of the reactor. A heavy oil pyrolysis and direct reduction steelmaking method characterized by burning and dissolving metal iron.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
