Materials for Clean H2 Production from Bioethanol Reforming

Hydrogen is one of the most important resources in providing food, fuel, and chemical products for our everyday life. Sustainable catalytic hydrogen production from bioethanol has gained significant attention in recent years due to globally diminishing fossil fuel supplies, which have necessitated the search for new chemical feedstocks.

Questions

  2. Does this catalyst need to be activated?

    1 answer

    1. Product 206199 is a ready-to-use product. No activation is required.

      Helpful?

  3. Dear Sir/Madam, I would like to have a specification on the ruthenium pellets. The size is specified as 3.2 mm, would this be the length or the diameter of the pellet? Could you also provide us with the other dimension? Best

    1 answer

    1. Unfortunately, the 3.2 mm particle size is the only available measurement for these pellets.

      Helpful?

  4. What is the pore size?

    1 answer

    1. This product is supplied as pellets with a size of 3.2 mm. Although the alumina pellets are considered to be quite porous, the pore size is not determined.
