Suitable for thermal coal and chemical raw materials

Low-sulfur and low-ash coal species are popular

High calorific value, mainly used for power generation and chemical raw materials

High hardness, less smoke when burning

Low calorie value and high moisture content

Commonly used for power generation and direct combustion

Open-pit coal mining

Underground mining

Removing impurities to improve coal quality

Reduce sulfur and ash

The main methods of transporting bulk coal

Relatively low cost

Long-distance coal transportation

Muchly affected by international market demand

Flexible but costly

Syngas is converted into methanol under the action of catalyst

Reaction conditions: high temperature and high pressure

Low pressure method

Medium pressure method

High pressure method

Remove impurities and moisture from methanol

Improve the purity of methanol

Safe storage of methanol

Methanol transport method

Mix methanol and gasoline

Reduce oil dependence and reduce emissions

Mix methanol and diesel

Improve combustion efficiency and reduce pollution

Convert methanol to ethylene and propylene

Used for the production of plastics and synthetic fibers

Convert methanol to acrylic acid

Used to produce acrylate chemicals

Methanol is used directly as energy for fuel cells

For portable power supplies and electric vehicles

Use methanol as a solvent

Widely used in pharmaceutical, pesticide and other industries

Destroy vegetation and terrain
