Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention more clear, the present invention is illustrated with the following specific examples, but the present invention is by no means limited to these examples. The following descriptions are only preferred embodiments of the present invention, and are only used to explain the present invention, and should not be interpreted as limiting the patent scope of the present invention. It should be noted that any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.

[0044] The acid strength of the zeolite catalyst of the present invention is tested by the Hammett indicator method. Use anhydrous cyclohexane as a solvent to prepare an indicator solution with a concentration of 0.1%-0.5%. Drop the indicator on the surface of the dry catalyst and observe the colo...

Abstract

The invention relates to a zeolite catalyst, which not only has the characteristics of a zeolite-type solid superacid, but also has a catalytically active component that is not easily lost, and can be rapidly separated by magnetism after the reaction, and can still maintain high catalytic efficiency after recovery, saving production costs. reduce environmental pollution.

Description

technical field [0001] The invention relates to a zeolite catalyst, in particular to an easily separated and highly efficient zeolite solid strong acid catalyst and its preparation method and application. Background technique [0002] With the rapid decline of petroleum and other chemical resources, the energy crisis is one of the severe problems that all countries in the world must face in the 21st century. British BP Petroleum Company pointed out in a survey conducted in 2005 that the remaining oil on the earth can only be used by humans for 40 years, and coal and natural gas resources can only last for 65 and 155 years. Therefore, the sustainable and efficient use of resources has become the focus of attention. [0003] Heterogeneous catalysis is a way to follow green chemistry and advocate sustainable development. At present, more than 90% of chemical synthesis processes are closely related to heterogeneous catalysis. Acid-catalyzed reactions are a very important clas...
