Abstract: 본 발명은 고온 다습한 가혹한 분위기에서 나프타의 접촉분해를 통하여 경질올레핀을 제조하는데 사용되는 성형촉매에 관한 것으로, 보다 구체적으로는, 0.01~5.0 wt%의 MnO 2 및 1~15 wt%의 P 2 O 5 가 제올라이트, 클레이 및 무기 산화물에 동시에 담지 되도록 혼합한 슬러리를 분무 건조 및 소성하여 제조되는 경질올레핀 생산용 탄화수소 접촉분해 촉매 및 그 제조방법에 관한 것이다. 본 발명에 따른 촉매는 망간과 인이 제올라이트와 무기 산화물을 동시에 수식함으로써, 얻어진 구형 성형촉매의 수열안정성을 향상시킬 뿐만 아니라, 제올라이트의 산점을 보호하여 나프타와 같은 C 4 이상의 탄화수소 접촉분해시 높은 경질 올레핀 수율을 얻을 수 있으며, 촉매의 제조방법이 간단하여 대량 생산이 용이하고 경제성이 제고되는 효과가 있다.
Abstract translation: 本发明涉及用于通过在高温高湿条件下的石脑油的催化裂化生产轻质烯烃的催化剂。 更具体地说，本发明涉及一种用于生产轻质烯烃的烃催化裂化催化剂及其制备方法，其中该催化剂是通过喷雾干燥和煅烧混合的浆料来制备的，使得0.01-5.0wt％ MnO 2和1-15wt％的P 2 O 5同时负载在沸石，粘土和无机氧化物上。 所公开的催化剂不仅改善了通过同时用锰和磷改性沸石和无机氧化物而得到的球形催化剂的水热稳定性，而且保护了沸石的酸性位点。 因此，可以在C4或更多的烃类如石脑油的催化裂化中以高产率获得轻质烯烃。 此外，通过催化剂的简单制造方法，可实现批量生产并提高经济效率。

Abstract: A high pressure fluidized bed reactor for manufacturing a granular polycrystalline silicon is provided to minimize the contamination due to particles, to obtain easily silicon grains of high purity and to keep the difference of pressure between inner and outer regions of an inner space of the fluidized bed reactor itself in a low range by using a pressure difference control unit. A reactor cell encloses a reaction tube(2), so that an inner space of the reactor cell is divided into an inner region and an outer region by the reaction tube. A silicon grain layer is formed and a silicon precipitation is generated in the inner region of the inner space of the reactor cell except the outer region. A gas inlet unit is used for supplying a predetermined gas to the silicon grain layer. A product exhaust unit is used for exhausting polycrystalline grains and an exhaust gas from the inner region. An inert gas connection unit is used for keeping the outer region under an inert gas condition. A pressure control unit is used for measuring and controlling the pressures of the inner and outer regions. A pressure difference control unit keeps the difference of pressure between the inner and outer regions in a predetermined range of 0 to 1 bar.
