Embodiment 1
[0036] The reactor for the production of low-carbon olefins adopts SAPO-34 molecular sieve catalyst as the active component, and the carbon deposition on the catalyst is 0.8wt%. The gas-phase methanol is preheated to 180°C for feeding. The reactor structure is as follows figure 1 shown. The secondary reaction zones are set in series, and each reaction zone is equipped with two raw material distributors for feeding. The angle between each raw material distributor and the tangent line of the wall of the reaction settlement zone is α (α=22°), and the outlet of the raw material distributor is facing the catalyst feeding pipe. outlet, the outlet nozzle layout structure is as follows image 3 shown. The contact area of the reactor material is located on the side wall of the reaction settling area, 3 / 5 of the height of the reaction settling area from the top of the reaction area; the structure of the product gas guide pipe is as follows: Figure 4 As shown, the diameter of the ce...
