Problems solved by technology

[0003] In addition, when the specific effect of the catalyst is tested, it can only be carried out on a micro-reactor in the laboratory. Since the large-scale production conditions cannot be simulated, the obtained test data only has a qualitative effect and cannot be obtained on a large scale. Quantitative parameters under optimized production conditions, which hinder the large-scale development of syngas to olefins

Embodiment 1

[0059] The reactor 300 will be described first below, which is a radial reactor.

[0060] see figure 1 , the test reactor 300 for syngas to olefins has a shell 10, which is a two-stage shell, including an upper shell and a lower shell, wherein the upper shell includes a middle cylinder 12 and an upper head 11 installed on the top of the middle cylinder . The lower shell is the lower end cap 13 . A first flange 22 is installed at the lower end of the middle cylinder 12 of the upper shell, and a second flange 23 is installed at the end of the lower head 13. Bolts 25 fasten the first flange 22 and the second flange 23 on the Together, the upper shell and the lower shell form a complete shell 10 .

[0061] In this embodiment, the housing includes two housing parts, the upper housing and the lower housing. It can be understood that in other embodiments, the housing can also be composed of three housing parts or four housing parts, that is, the housing is composed of at least Co...

Embodiment 2

[0098] A synthesis gas-to-olefins production process, the production process is carried out using the reaction device described in Example 2, and the reactor 300 is filled with a silicon-aluminum catalyst, and the production process specifically includes the following steps:

[0099] (1) After being heated by the electric heater 370, the nitrogen gas enters the heat medium channel of the start-up heater, exchanges heat with the synthesis gas, and then is discharged.

[0100] (2) The synthetic gas enters the adsorber through the inlet A311 of the adsorber 310 for purification, and the purified synthetic gas is discharged from the outlet A312 of the adsorber 310 into the raw material pipe 315, and is then divided into two streams of synthetic gas, of which A stream of synthesis gas enters the refrigerant channel of the start-up heater 320 along the branch pipe A316, and enters the reactor 300 for reaction after being indirectly heated by nitrogen. Another stream of synthesis gas...

Abstract

The invention discloses a reaction device for synthesis gas to olefin test, which comprises a reactor, an adsorber, a start-up heater, a primary cooler, a secondary cooler, a steam drum and an electric heater; the outlet A of the adsorber is connected with two One of the branch pipes is connected to the gas inlet of the reactor after passing through the refrigerant channel of the start-up heater, and the other branch pipe is connected to the gas inlet of the reactor after passing through the refrigerant passage of the primary cooler; the gas outlet of the reactor passes through the heat of the primary cooler. After the medium channel, it is connected to the heat medium channel of the secondary cooler; the refrigerant inlet of the reactor is connected to the water outlet of the steam drum, and the refrigerant outlet of the reactor is connected to the water inlet of the steam drum; the material channel of the electric heater is connected to the heat medium channel of the start-up heater . The present application also provides a process for producing olefins from synthesis gas, which is carried out by using the above-mentioned reaction device. The reaction device and production process provide certain conditions for the direct preparation of olefins from the synthesis gas from the laboratory to the large-scale production.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a test reaction device for preparing olefins from synthesis gas and a production process for preparing olefins by using the reaction device. Background technique [0002] At present, the direct production of olefins using syngas as raw material has been successfully realized in the laboratory, but there are still many problems to be solved in order to realize large-scale production. Especially as the lack of pilot equipment from laboratory to large-scale production, the lack of pilot equipment also leads to the lack of pilot equipment and corresponding processes, which makes the large-scale production of olefins directly from syngas stagnate, and is still Based on laboratory research. [0003] In addition, when testing the specific effect of the catalyst, it can only be carried out on a micro-reactor in the laboratory. Since the large-scale production conditions cannot be simul...
