Description

Methane CAS NO 74-82-8 is the simplest alkane and the primary component of natural gas, serving as a fundamental building block for the chemical and energy industries. Its high hydrogen-to-carbon ratio makes it an essential feedstock for producing hydrogen, synthesis gas, and a vast array of downstream chemicals. This product is critical for industrial operations in sectors including energy generation, chemical manufacturing, and fuel production. We supply high-purity methane in various grades to meet the stringent demands of global industrial applications.

Application

• Fuel and Energy Production: Primary component in natural gas for heating, electricity generation, and as a compressed (CNG) or liquefied (LNG) fuel for vehicles.
• Chemical Synthesis Feedstock: Key raw material for steam reforming to produce hydrogen and synthesis gas (syngas), which are precursors to ammonia, methanol, and other vital chemicals.
• Industrial Processes: Used as a fuel gas in industrial furnaces, kilns, and for metal cutting and welding applications.
• Hydrogen Production: Serves as the dominant feedstock for large-scale hydrogen manufacturing via steam methane reforming (SMR).
• Laboratory and Calibration: High-purity grades are used as a calibration standard in analytical instrumentation and for research purposes.
• Semiconductor Manufacturing: Utilized in chemical vapor deposition (CVD) processes within the electronics industry.
