There are various types of gas-solid contacting reactors. Fluidized bed is one kind of gas-solid contacting reactor and employed for various processes. However, a feature that is advantageous for one application is sometimes found to be a disadvantage for another application. Therefore, engineers should prepare various types of gas-solid contact reactors as many as possible so that they can choose the most suitable one. The present author has proposed a novel gas-solid contacting reactor called “rotating coil-shaped spiral”. This article briefly summarizes the state-of-art of the development of “rotating coil-shaped spiral” reactor concerning to solid transportation, gas-solid contact and pressure drop during gas feed, and heat transfer between wall and solids. The future perspective is also discussed.
