(54) Example of Catalytic Reactions

(55) A fixed bed reaction is taken as an example, but the catalyst is also applicable to a fluidized bed reactor. The apparatus was equipped with gas mass flow meters and online product analysis chromatography (the tail gas of the reactor is directly connected with the metering valve of chromatography, and thus periodic and real-time sampling and analysis will be achieved).

(56) 2 g of the above catalyst in the present invention was placed in a fixed bed reactor. The air in the reactor was replaced with Ar; and then the temperature was raised to 300° C. in the H.sub.2 atmosphere, and then the syngas (H2/CO molar ratio=0.2-3.5) was switched. The syngas can also include CO.sub.2, wherein the volume concentration of CO.sub.2 in the syngas is 0.1-50%. The pressure of the syngas is 0.5-10 MPa. The temperature is raised to reaction temperature of 300-600° C., and the space velocity of the reaction raw gas is regulated to 300-10000 ml/g/h. On-line chromatography is used to detect and analyze the product.

(57) The reaction performance can be changed by changing the temperature, pressure and space velocity. The selectivity of the ethylene and the propylene in the product is as high as 78-87%, and the conversion rate of the raw material is 10-60%. Due to the effective synergy between the zeolite and the oxide, mass production of the methane and C.sub.4+ hydrocarbons is avoided.

(59) The reaction results of reference examples 2-9 show that MOR which is post-processed by the fatty amine has a significant effect on the regulation of catalytic performance. Compared with the catalysts which are not regulated with the fatty amine, the regulated catalyst significantly reduces the selectivity of the methane and hydrocarbons above C.sub.4 and also improves the selectivity of the light olefin and the ethylene.

(60) The component I in the catalyst adopted in reference example 10 is metal ZnCo. The molar ratio of ZnCo is 1:1. Other parameters and the mixing process are the same as those of catalyst C.

(61) The component I in the catalyst adopted in reference example 11 is TiO.sub.2. Other parameters and the mixing process are the same as those of catalyst C.

(62) The catalyst adopted in reference example 12 is a sample containing only component I ZnO #1 without the MOR zeolite, and the reaction conversion rate is very low. The products mainly comprise by-products such as dimethyl ether and methane, and almost no ethylene is produced.

(63) The catalyst adopted in reference example 13 is a metal oxide containing only MOR9 zeolite of component II without the component I and acting as an active ingredient, and the catalytic reaction almost has no activity.

(64) Reference examples 12 and 13 indicate that reaction effects are extremely poor when only component I or component II exists, and do not have the excellent reaction performance in the present invention.
