Particle technology is used in many industries especially the chemical and materials industries. Fluidization is a very efficient method in handling powdered particles and many types of fluidized bed reactors have been developed. In the past 30 years, high-velocity fluidized bed reactors were found to be more efficient and such high-velocity reactors include the turbulent fluidized bed reactors and the circulating fluidized bed reactors. Turbulent bed reactors provide high reaction intensity and compact size as well as high mass transfer, but suffers from particle backmixing, while circulating bed reactors have less backmixing and high mass transfer, but are bulky and costly to build. The first proposed research project is to continue an endeavour to develop a new circulating turbulent fluidized bed reactors that combine the benefits of both.

颗粒技术在许多行业中使用，特别是化学和材料行业。 流化是处理粉末颗粒的一种非常有效的方法，已经开发了许多类型的流化床反应器。 在过去的30年中，高速流化床反应器被发现是更有效的，并且这样的高速反应器包括湍流流化床反应器和循环流化床反应器。 湍流床反应器提供高的反应强度和紧凑的尺寸以及高的质量传递，但是遭受颗粒返混，而循环床反应器具有较少的返混和高的质量传递，但是体积大并且建造成本高。第一个拟议的研究项目是继续努力开发一种新的循环湍流流化床反应器，它将两者的优点联合收割机结合起来。
