Hydrogen Gas Plant Methanol cracking for hydrogen production generator
Product Introduction
CJDL-I serise machine is a thermal treatment protective atmosphere generator jointly developed by our company and the Applied Chemistry Research Institute of North University under the direct jurisdiction of the Ministry of National Defense.
How it works of the CJDL-I serise machine :First, vaporize the incoming methanol to a specific temperature range. The methanol vapor then comes into full contact with the catalyst in a low-temperature environment (260°C), where it decomposes to produce a reductive mixed gas primarily consisting of hydrogen and carbon monoxide. This mixed gas is then cooled using specialized condensation equipment based on its different components and dew point temperatures before entering the thermal treatment device.
Reducing gas mixture produced enters the furnace chamber and reacts chemically with the small amount of oxygen brought in by the workpieces and the oxidized surface of the workpieces at high temperatures. The reaction products are H2O and CO2. This oxidative atmosphere is displaced from the furnace chamber as more cracking gas mixture enters, ultimately achieving chemical equilibrium within the furnace atmosphere, thus realizing the purpose of atmosphere protection.

CJDL-I serise Methanol low-temperature cracking machine
1. The process of atmosphere protection in metal heat treatment involves continuous cycles of oxidation and reduction reactions. The ultimate goal of atmosphere protection is to maintain a balance between oxidation and reduction reactions within the furnace. Typically, people adjust the protective atmosphere appropriately to meet the heat treatment requirements of different metal materials. However, the protective atmosphere for heat treatment should generally satisfy:

It has already successfully replaced ammonia decomposition equipment in multiple industry sectors.
2.Crackers are currently widely used in various metal heat treatment fields: bearing steel annealing/quenching protection, wire annealing, carburizing, and quenching protection in the fastener industry, mold steel quenching protection, tool steel annealing/quenching protection, copper annealing and brazing protection, powder metallurgy, and heat treatment protection for various automotive parts.
