High-purity Dimethyl Ether (DME) 99.99% Industrial Fuel | Jiu Runfa

Dimethyl ether product description

Dimethyl ether is a colorless, non-toxic gas with a slight eal aroma that can be liquefied for storage. It is an important clean energy source and chemical raw material, known as a "green alternative to liquid fuel gas."
Due to its advantages such as complete combustion, clean emissions, and convenient storage and transportation, DME has been widely used in various fields, including energy, chemicals, refrigeration, and aerosol propellants.

Product Specifications

Key characteristics of dimethyl ether

Clean and Environmentally Friendly:

· Combustion products are primarily carbon dioxide and water, with no smoke, sulfur, or particulate matter emissions.

· Conforms to the trend of clean energy development and can significantly reduce air pollution.

Excellent Combustion Performance:

· Excellent ignition performance, high combustion efficiency, and no carbon deposits.

· Has a high cetane number (approximately 55-60) and superior combustion stability to diesel.

Easy to Liquefy and Store and Transport:

· Can be liquefied at room temperature with slight pressurization (approximately 0.5 MPa).

· Storage and transportation methods are similar to those of liquefied petroleum gas (LPG), allowing for shared storage and transportation facilities.

Wide Applications:

· Can be used as household gas, a diesel alternative fuel, a spray propellant, a refrigerant, and a chemical raw material.

· Is a key intermediate for a variety of high-end chemical products (such as dimethylamine, dimethylsulfuric acid, acetic acid, and polyoxymethylene).

Diverse Sources:

· Can be synthesized from a variety of feedstocks, including coal, natural gas, biomass, and methanol.

· Supports renewable energy routes (such as biomass-based dimethyl and biomethanol).

High Safety:

· Non-toxic and non-corrosive, with stable combustion and no significant environmental damage.

· Wide explosion range (3.4% to 27%), but easy to detect and control.

Immense Development Potential:

· An important new energy source that replaces traditional fossil fuels and promotes energy transition.

· Against the backdrop of achieving carbon peak and carbon neutrality, dimethyl is becoming a vital component of the green energy industry.

Applications of dimethyl ether

Clean Energy Sector

Application Scenarios:

Liquefied Petroleum Gas (LPG) Alternatives:

Industrial Fuel: Achieves clean combustion in ceramic kilns and metal processing, reducing sulfur oxide emissions.

Automotive Fuel:
Diesel Alternatives: Used in buses and trucks with converted diesel engines; Blended Fuel: Blended with LPG or diesel to improve combustion efficiency.

Power Generation Fuel:
Gas Turbines: Used in distributed power plants to reduce nitrogen oxide emissions.
Fuel Cells: Hydrogen produced through dimethyl ether reforming for use in hydrogen fuel cell power generation.

Chemicals and Materials Production

Core Products:
Methyl Acetate:
Production Process: Carbonylation reaction of dimethyl ether with carbon monoxide.
Uses: Used in the production of paint solvents, fragrances (such as benzyl acetate), and adhesives (such as general-purpose glues).

Dimethyl Sulfate:
Uses: Used in the production of methylating agents in the pharmaceutical industry (such as for the synthesis of vitamin B1) and pesticides (such as glyphosate).

Polyoxymethylene (POM):
Process: Formaldehyde is produced by the oxidation of dimethyl ether, then polymerized into engineering plastics.
Uses: Automotive gears, electronic components, medical devices.

Hydrofluoroolefins (HFOs):
Uses: Environmentally friendly refrigerants (e.g., HFO-1234yf), used to replace ozone-depleting CFCs.

Aerosols and Daily Chemicals
Specific Products:
Personal Care Aerosols:
Hairsprays, Fragrances: Reduce flammability by replacing traditional propellants (e.g., propane and butane).

Antiperspirants, Shaving Foams: Provide a gentle spray experience.

Household Aerosols:
Air Fresheners, Insecticides: Environmentally friendly and residue-free.

Medical Aerosols:
Inhalants: For example, asthma inhalers (requires high-purity DME).

Industrial and Specialty Applications
Typical Case:
Polyurethane Foaming Agents:
Uses: Building insulation panels, refrigerator insulation layers, automotive seat foam, alternatives to fluorocarbons (e.g., HCFC-141b).

Electronics Industry Cleaning Agents: Ultra-pure DME: Used for cleaning semiconductor wafers and removing photoresist residue.

Laboratory Solvents: Special Reaction Media: For example, solvents or extractants in low-temperature reactions.

Environmental Protection and Emerging Technologies

Innovative Applications: Marine Fuel: Heavy Oil Alternative: Nordic countries are piloting the use of DME-powered ships to reduce sulfur emissions.

Energy Storage Media: Chemical Energy Storage: DME is used as a hydrogen carrier, releasing hydrogen through catalytic reforming for use in fuel cells.

Carbon Neutralization Pathways: Green DME: Synthesized using biomass or carbon dioxide hydrogenation, contributing to reduced carbon emissions. Key Advantages and Challenges:

Advantages

Environmentally Friendly: No sulfur is produced during combustion, resulting in low particulate matter emissions and excellent carbon neutrality potential.

Economically Sound: Raw material methanol is readily available (coal/natural gas to methanol), and costs are controllable.

Safely: Non-toxic, with a narrow explosion limit (3.4%~17%), lower storage and transportation risks than propane.
