Embodiment 1

[0049] HZSM-5 molecular sieves are usually synthesized in a conventional homogeneous reactor, and the synthesis conditions are:

[0050] First mix 12.50g Tetraethyl Tetrasilicate (silicon source), 12.00g Tetrapropylammonium Hydroxide (template), and 70g water (by adjusting the addition ratio of silicon source and water, the particle size of the synthetic molecular sieve can be changed) , stirred at 80°C, condensed and refluxed for 24h, then added 0.24g NaOH and 0.46g Al(NO 3 ) 3 9H 2 O (aluminum source), transferred to a polytetrafluoroethylene-lined stainless steel autoclave for static hydrothermal synthesis at 170°C for 24 hours, after quenching, centrifuged to wash the supernatant to pH ≈ 7, and then transferred to blast drying Oven dried at 110°C for 12 hours, then transferred to a muffle furnace and roasted at 550°C for 6 hours to remove the template agent, and after cooling, the sample was taken out to obtain NaZSM-5 zeolite, which was then treated with 1mol / L NH 4 NO...

Abstract

The invention discloses an internal rotation homogeneous reaction device with a locating system. The internal rotation homogeneous reaction device comprises a box body, wherein an electrothermal air blasting heating device, a rotating device, a locating device and reacting kettles are arranged inside the box body; the rotating device consists of a rotating motor, a center rotating shaft, a rotating bracket and a plurality of size-adjustable clamping slots; the rotating motor is arranged on one side inside the box body; the rotating motor is connected with one end of the center rotating shaft;the center rotating shaft penetrates through the whole box body; the rotating bracket is arranged on the center rotating shaft; the multiple size-adjustable clamping slots are formed in the rotating bracket; and the reaction kettles are arranged in the clamping slots. The box body is made of high-quality cold-rolled steel plates, and the surface is coated with electrostatic powder to form a hard and firm coating layer which is extremely high in antirust capacity. A working chamber is a high-quality stainless steel plate which is in a fillet style, smooth, fluent and very easy to clean. A spacebetween the box body and the working chamber is filled with an ultrafine glass wool heat isolation material, so that high heat preservation performance is realized, and stability and accuracy of temperature in the box are effectively guaranteed.

Description

technical field [0001] The invention relates to a chemical reaction experiment device, in particular to an internal rotation homogeneous reaction device with a positioning system. Background technique [0002] Homogeneous reactors are widely used in chemical and chemical engineering and other experimental fields. Its main function is to test the reaction of the same component medium under different conditions or to test the reaction of different components of the medium under the same conditions. For example, in the process of preparing molecular sieves by hydrothermal crystallization, an aqueous solution is used as the reaction medium, and a high-temperature and high-pressure reaction environment is obtained by heating the reactor, so that insoluble or insoluble substances are dissolved and recrystallized to form dispersed nanocrystalline nuclei. At present, there are many types and structures of homogeneous reactors, but the basic principles are roughly the same. They all ...
