Write short note on Multiphase Reactors.
Answers
A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst possibly shaped as tiny spheres) at high enough velocities to suspend the solid and cause it to behave as though it were a fluid. This process, known as fluidization, imparts many important advantages to the FBR. As a result, the fluidized bed reactor is now used in many industrial applications.
multiphase reactors includes,for instance,gas liquid solid and gas-liquid-liquid reactions. In many importent cases reactions between gases and liquids occure in presence of phorus solid cytalist the reaction typically occurs at cytalic site at solid surface.
