The deficient of world energy resource directly restricts the development of the world economy. So every state is paying tremendous expense to find the efficient method to resolve the deficient of energy resource. Fortunately, the resource of coal and natural gas is rich in the world, how to make use of these two resources efficiently and cleanly becomes the significant problem that the circle of industry and science technology fully concern about in the world. With the development of coal chemical engineering and C1 chemistry, the researchers are looking for other method to develop the coal and natural gas besides synthesis the NH3 and CH3OH. Because of the good characteristic of DME, the synthesis of DME from water gas becomes one of the heatpoints of C1 chemical engineering. The synthesis technology includes two sorts, such as one-step method and two-step method. The one-step method makes use of the chemical balance, so it has larger development space. It is known to all that the slurry bed has a lot of advantages which make the one-step synthesis of DME in slurry bed becomes the popular technique of DME synthesis. From...
