SPINNING DISC REACTOR WITH SPIRAL PASSAGEWAY FOR HEAT TRANSFER FLUID

摘要

There is disclosed a reactor apparatus including a support element that is rotatable about an axis and which has a first surface generally centred on the axis. The first surface is adapted for outward radial flow of a thin film of fluid phase reactant thereacross when supplied thereto as the support element is rotated. The support element also has a second surface opposed to the first surface and which is in thermal communication with the first surface. The second surface is provided with a spiral passageway generally centred on the axis and also with means for supplying a heat transfer fluid to the spiral passageway. By providing a spiral passageway for the heat transfer fluid, improved heat transfer from the first surface to the heat transfer fluid is obtained.
