Abstract

The invention discloses a small methanol hydrogen production apparatus for driving a hydrogen engine. The apparatus comprises a methanol water storage tank, an electromagnetic metering pump, a vaporization pipe, a cracking pipe, electromagnetic induction heating rods, and a hydrogen storage buffer tank, wherein the methanol water storage tank, the electromagnetic metering pump and the vaporizationpipe are in communication in sequence, the vaporization pipe is connected with the cracking pipe through a pipeline, the vaporization pipe and the cracking pipe are heated by the electromagnetic induction rods, the top end of the vaporization pipe is connected with the cracking pipe through the pipeline, and a hydrogen outlet of the cracking pipe is connected with the hydrogen storage buffer tank. The apparatus uniformly raises the temperature to 240-260 DEG C by electromagnetic induction heating for conversion to produce hydrogen. The apparatus uses methanol to produce hydrogen to provide power for the hydrogen engine, heat transfer oil, a heat transfer oil pump and a circulation system are avoided, and the apparatus can be used by cooperating with existing hydrogen fuel cell vehicle through cooperating on engines.

Description

technical field [0001] The invention relates to the technical field of methanol hydrogen production, in particular to a small methanol hydrogen production device driven by a hydrogen engine. Background technique [0002] Methanol hydrogen production refers to the process of mixing methanol with water vapor and passing through the action of a catalyst under certain temperature and pressure conditions, so that methanol undergoes a cracking reaction and finally obtains hydrogen and carbon dioxide. The main chemical reaction formula of methanol and steam reforming is as follows: [0003] CH 3 OH→CO+2H 2 (1); [0004] h 2 O+CO→CO 2 +H 2 (2); [0005] CH 3 OH+H 2 O→CO 2 +3H 2 (3); [0006] The specific method of methanol hydrogen production in industry is to mix methanol and desalted water in a certain proportion and send them to the vaporization tower for vaporization. The vaporized water methanol vapor is superheated by the superheater and then enters the converte...

AI Technical Summary

Problems solved by technology

The main defects of the methanol-hydrogen production equipment in the prior art are: 1. The overall equipment is huge, complex and expensive; 2. It is inseparable from the disadvantages of one machine and one skid-mounted design; 3. It is used to provide superheater and converter The heat transfer oil of the heat source is heated by a stainless steel thermocouple. The heating area of ​​the heat transfer oil is uneven, the power consumption is large, the structure is tight, and the service life is short.
