Abstract

The invention discloses a catalytic heating coupled methanol hydrogen production process, which belongs to the field of hydrogen production, and specifically relates to the technical field of methanol hydrogen production, in order to solve the problem that the existing methanol hydrogen production process requires external heating to start, additional equipment is required, and energy consumption is high. It covers a large area, including a catalytic oxidation reactor and a methanol hydrogen production system. In the catalytic oxidation reactor, methanol and air in the raw material are oxidized at a temperature above 10°C, and the catalyst layer is oxidized at normal temperature, and the catalytic oxidation reaction occurs. The generated heat provides thermal energy for the start-up of the methanol hydrogen production system. Under the condition of no heat source, the raw material methanol and air undergo a catalytic oxidation reaction in the catalytic oxidation reactor under the action of the combined catalyst layer, and the heat generated provides heat energy for the start-up of the methanol hydrogen production system, making the entire methanol hydrogen production process run at room temperature It starts from the bottom, does not require external heating to start, and does not require additional external heat source equipment. The equipment occupies a small area and consumes low energy.

Description

technical field [0001] A catalytic heating coupled methanol hydrogen production process, the invention belongs to the field of hydrogen production, and specifically relates to the technical field of methanol hydrogen production. Background technique [0002] After the reformed gas of the traditional methanol steam reforming hydrogen production process passes through pressure swing adsorption or membrane hydrogen extraction, the required product H is obtained. 2 In addition, the rest is analytical gas, and the H in the analytical gas 2 The content is 30%-40%; the product H of the current common methanol direct cracking process 2 , CO, used tail gas H 2 The content is above 95%. There are generally two ways to deal with it. One is to send it into the boiler combustion system for boiler combustion. Due to the unstable gas source, there are obvious safety hazards to the boiler combustion system; Great and also cause a waste of clean energy. The treatment of this combustible...
