Application

Nickel on silica/alumina can be used as an efficient catalyst in a variety of applications such as:
  • in plastic waste pyrolysis for the production of fuel[1]
  • to study the supercritical water reforming of glycerol[2][3]
  • in the supercritical water reforming of acetic acid for the production of hydrogen[4]

Questions

1–2 of 2 Questions  
  1. What is the typical size of the powder particles ? Is it bigger than µm?

    1 answer
    1. In the past, the supplier has mentioned 90% of particle volume being less than 15 microns, 50% being less than 6 microns, and 10% being less than 2 microns. Most particles should fall between 2 and 15 microns. However, this value cannot be quality guaranteed as this parameter is not tested internally.

      Helpful?

  2. Is it possible to know the Si/Al ratio of such material?

    1 answer
    1. Per the manufacturer, this product has a silica and alumina content of approximately 10 wt.% each.
