Hydrogen Generator, Methanol Cracking System, Industrial Application
Besides endothermic gas or endo gas, more and more methanol is used
for the thermal treatment of metals as a protective gas. The
methanol is directly inserted into the furnace and cracked there.
CH3OH → CO + 2 H2
Carbon monoxide and hydrogen are formed. The Methanol cracking gas
is an excellent carrier gas.
Hydrogen and carbon monoxide are reducing agents and avoid
oxidation or corrosion of metal surfaces in a furnace. It has to be
taken into account, however, that carbon monoxide increases the
carbon content of the steel. Methanol cracking gas can therefore be
used for the surface hardening of steel by carbonization or
carburization. Carbon concentration can be increased up to the
saturation level of austenite in close surface areas (around 1mm
deep).To control the carbonization, water vapor can be added or
nitrogen can be used for dilution.
Technical Figures:
1. In a hot air stream, 95% to 98% of moisture can be evaporated immediately.
2. Quick drying speed: the surface area of material liquid through atomizing is increased greatly.
3. Product has good uniformity, fluidity, solubility, high purity, and quality.
4. For liquid containing 0~60% damp(particularly maybe 90%), it can be dried to powder through drying
one time.
5. After drying, not necessary to crush, the sieve therefore reducing the productive procedure.
6. For the size, bulk density and moisture of the product can be adjusted within specific scope by exchanging
operation conditions.
7. large flexibility of operation
8. No high requirement for factory buildings
Applications:
1. Carbonisation, Carbonization, Carburization, Carburisation
2. Sintering
3. Annealing of steel with high carbon content
4. Normalizing
Technical features:
1. It is a mature production technology, which can be operated
safely and reliably.
2. The feedstock is easy to get at a relatively stable price and is
transported and stored easily too.
3. The process flow is short and simple.
4. Both energy consumption and production cost are relatively low.
5. Less land occupation and investment, which can be recovered in a
short period.
6. Operation is simple and easy, and automation is high.
7. No environmental pollution.

Process Flow Diagram
The mixture of methanol and demineralized water, after
pressurizing, evaporating, and superheating to a certain
temperature, is fed into a reactor, where the reforming gases
including H2, CO2, CO, etc. are formed under the action of the
catalyst. The mixed gas is treated through the purification
technology of PSA to get high-purity hydrogen in one cycle.
