본 발명은 함산소 화합물로 프로필렌, C4탄화수소류를 제조하는 방법 및 그 장치에 관한 것이다. 해당 방법은, 80wt.%이상의C5이상의 탄화수소류는 순환하여 촉매 크래킹 상승관에 진입하여, 크래킹 반응이 발생하여, 프로필렌, C4탄화수소류를 함유하는 생산물을 생성하고, 따라서 에틸렌 알킬화 반응 속도, 반응기 단위 체적 생산 능력을 향상시킬 수 있다. The present invention refers to a method and device for preparing propylene and C4 hydrocarbons from oxygen-containing compounds. By means of circulating 80 wt.% or more of the hydrocarbons with 5 or more carbons in the product into a catalytic cracking lift pipe to perform a cracking reaction to generate a product containing propylene and C4 hydrocarbons, the method improves the reaction rate of ethylene alkylation, and the unit volume production capacity of reactor is high.
