EXECUTIVE SUMMARY The purpose of this project was to select a suitable reactor for the syngas synthesis prior to the dimethyl ether production, to evaluate relationships between parameters inside the reactor and size it. All types of reactors were evaluated and the packed bed reactor was chosen to be the most suitable reactor for the process and it is used commonly used by industries. The catalyst selected to go with the PBR was nickel on alumina support(Ni/〖Al〗_2 O_3).It was found that the catalyst weight required is 26797 kg and the volume of the reactor to be 64.03m3.

This process unit is widely used in industries to convert raw materials into products. There are a lot of factors that affect the design of a chemical reactor depending on the type of chemical reaction that will be taking place such as; the mode of operation this could either be batch or continuous, the type of phases involved homogenous or heterogeneous, and the reactor geometry required. There are many types of reactors and this report will focus on the selection and detailed design of an appropriate chemical reactor suitable for the steam reforming process prior to the direct dimethyl ether
