Argonne Laboratories to Develop New High Temperature Membrane Ethylene Will Set off the Revolution of Ethylene Production Industry

The U.S. Department of Energy's Argonne National Laboratory has introduced a groundbreaking, eco-friendly ethylene production process that could spark a major industrial transformation. Ethylene, the most fundamental organic chemical in the world, is essential for manufacturing plastics, solvents, and other everyday materials. This new method promises to revolutionize how ethylene is made, offering a cleaner and more energy-efficient alternative to traditional methods. At the core of this innovation is a high-temperature membrane that selectively allows hydrogen to pass through while blocking methane and other gases. This breakthrough enables the extraction of pure hydrogen from methane vapor, which is then used to generate ethylene. Unlike conventional processes that rely on energy-intensive cracking of ethane and produce harmful byproducts like nitrogen oxides, carbon dioxide, and carbon monoxide, this system avoids those environmental drawbacks. Every year, global ethylene producers create around 75 million tons of the chemical, contributing significantly to greenhouse gas emissions. The new process, however, is designed to be far more sustainable. By using the hydrogen-permeable membrane, the reaction can generate its own energy—hydrogen reacts with oxygen in the air to provide the necessary power, reducing external energy inputs. Additionally, the membrane reactor continuously removes hydrogen during the process, shifting the reaction toward higher ethylene yields than what is possible under normal equilibrium conditions. This not only increases efficiency but also reduces the number of steps required in production, lowering costs and improving scalability. Argonne’s research team is now looking to partner with industry leaders to bring this technology to market as quickly as possible, aiming to commercialize high-temperature membranes and usher in a new era of green chemical manufacturing.

Metal Injection Molding Service

Metal Injection Molding (MIM) service is a new metal processing technology that combines metal powder with a binder to form a mixture that is injected and molded into a green compact. The MIM service process includes the following steps:

  1. Preparation of metal powder: The required metal powder is mixed with a binder such as a thermoplastic or thermosetting plastic by ball milling or other methods to form a homogeneous mixture.
  2. Injection molding: The mixture is placed in an injection molding machine, heated to melting, and injected into a mold to form a green compact of the desired shape.
  3. Sintering: The green compact is subjected to high-temperature sintering to remove the binder and densify the metal powder.
  4. Finishing: The sintered compact is finished to obtain the required dimensions and accuracy of the product.

The MIM service process is characterized by high precision, high efficiency, and ability to process complex shapes, and is widely used in the electronics, machinery, automotive, and aerospace industries.
