补充资料:浆液反应器
分子式:
CAS号:
性质: 又称浆式反应器浆料反应器或浆态反应器。是一类液-固或气-液-固反应器,反应器中充满液体,固体以粉末或微粒状存在液体中构成浆状物。固体催化剂在反应液体物料中处于运动状态的气、液、固三相反应器。有机械搅拌浆液反应器、连续浆式反应器、半连续浆式反应器等类型。结构形式有釜式和塔式两种。液相物料可有两种不同作用:液相仅为惰性热载体;液相为反应物。前者如费雷尔-托罗帕法由CO和H2合成烃类或含氧有机物的过程。后者如不饱和烃类的加氢反应。对于液-固两相反应,需有搅拌桨进行搅拌。若固体为催化剂进行气-液反应,则可通过气体进行搅拌。浆料反应器床层温度均匀,且温度容易控制。气-液-固三相浆料反应器多用于液体的加氢反应。此种反应器便于催化剂再生,传热和温度控制比较方便,催化反应效率高;但液固比高,易发生均相副反应,催化剂粒子与液相分离比较困难。
