Embodiment Construction

[0023] The device for dehydrogenating liquid organic hydrides of the present invention has a shell, a reaction tube, a liquid distributor and an electromagnetic coil. The housing serves as a reaction vessel for the dehydrogenation of liquid organic hydrides. The reaction tube is used for heating the liquid organic hydride to make it undergo dehydrogenation reaction on the surface of the reaction tube. A heat source medium can be introduced into the reaction tube to provide heat for the hydrogenation reaction. The reaction tubes are preferably uniformly arranged in the device, so that the liquid organic hydride is evenly distributed on the outer surface of the reaction tubes. The material of the reaction tube can be selected from metals that are easy to magnetize and demagnetize, such as soft iron. The shape of the reaction tube is preferably a circular tube, but not limited thereto.

[0024] The liquid distributor is used to spray the organic hydride liquid onto the outer s...

Abstract

The invention discloses a device for dehydrogenating liquid organic hydride. The device is composed of a shell, a liquid distributor, reaction tubes, electromagnetic coils, and a fluid inlet / outlet adapter tube; the reaction tubes are evenly arranged in the device, a thermal medium flowing in each tube provides heat for reaction; the electromagnetic coil is an electrified coil wound on two ends of each reaction tube according to a certain direction, each reaction tube can be magnetized after the electronic coil is electrified; a catalyst is adsorbed to the outer side of the tube, and an organic hydride thin liquid film is formed to generate the dehydrogenation reaction. Compared with the prior art, the device disclosed by the invention has the following advantages that the filling and replacing of the catalyst are extremely simple and convenient by performing power on / power off operation on the electromagnetic coils, and the continuous production requirement can be satisfied.

Description

technical field [0001] The invention relates to a reaction device for producing hydrogen by using liquid organic hydride and low-temperature heat energy, and more particularly relates to a horizontal tube falling film catalytic dehydrogenation device with a surface magnetic solid-carrying catalyst. Background technique [0002] Hydrogen energy is an important resource and plays an irreplaceable role in the fields of energy, chemical industry, and medicine. The dehydrogenation of organic hydrides is an important means of producing hydrogen, such as cyclohexane dehydrogenation, cyclohexanol dehydrogenation, Dehydrogenation of isopropanol, etc., in addition to obtaining hydrogen, can also obtain chemical products such as benzene, cyclohexanone, and acetone, which occupy an important position in the industry. At present, dehydrogenation reactions in industry can be divided into two categories, gas-phase and liquid-phase reactions. The gas phase reaction is generally carried out...
