Example Embodiment

[0025] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0026] The methanol steam hydrogen production process of the present invention is as follows figure 2 As shown in the figure, using methanol and desalinated water as raw materials, through preheating, gasification, superheating, and conversion processes in turn, the reformed gas is obtained, and the reformed gas is then subjected to pressure swing adsorption to obtain product hydrogen, and the tail gas is discharged, wherein the conversion process is carried out by the heat transfer oil system. Provide heat, the exhaust gas enters the heat transfer oil system, and conducts a catalytic combustion reaction with the air under the action of a catalyst for catalytic combustion reaction, which is used as a heat source to heat the heat transfer oil as a heat carrier, and part of the gasified methanol also participates in the catalytic combustion reaction. ...

Abstract

The invention discloses a methanol steam hydrogen production technology by using catalytic combustion flue gas as a heat source, relating to a hydrogen production technology, and aiming to solve the problem that tail gas is discharged but is not utilized to result in resource waste in the traditional methanol steam hydrogen production technology. Methanol and desalted water as raw materials are orderly preheated, gasified, overheated and converted to obtain converted gas; then the converted gas is adsorbed at variable pressure, the product hydrogen is obtained, and tail gas is discharged, wherein the heat quantity is supplied by heat conducting oil in the converting procedure, the tail gas generates the heat quantity through catalytic combustion and conducts the heat quantity to the heat conducting oil in a heat conducting system.

Description

technical field [0001] The invention relates to a hydrogen production process, in particular to a hydrogen production process from methanol steam. Background technique [0002] The methanol steam reforming hydrogen production device uses methanol and desalted water as raw materials under certain temperature and pressure conditions. With the help of the catalyst in the methanol steam reforming reactor, the raw material and water vapor are produced in the reformer tube. Conversion reaction to produce synthetic ammonia raw material gas (ie hydrogen). [0003] Such as figure 1 As shown, in the currently widely used process, the raw material methanol and desalted water are first prepared in a certain proportion, and under pressurized conditions, they go through the steps of preheating, gasification, and superheating respectively, and the superheated raw material mixture is carried out in the converter Gas-phase catalytic conversion reaction to obtain reformed gas, in which H 2...
