SHU Catalyst

Butadiene Hydrogenation Activity

The primary purpose of SHU catalyst is the elimination of 1,3 butadiene via hydrogenation.  Butadiene activity and conversion depends on:

  • Catalyst metal type, content, and dispersion
  • Operating temperature and pressure
  • Residence time (LHSV) and hydrogen feed
  • Catalyst age
  • Effect of feed impurities
Hydrogenation of 1-3 Butadiene
Hydrogenation of 1,3 Butadiene to 1-Butene

Olefin Selectivity

SHU Catalyst will isomerize and saturate olefins at low diene concentration.  Selectivity, which is the avoidance of olefin saturation, depends on:

  • Catalyst metal type, content, and dispersion
  • Operating temperature and hydrogen feed
Olefin equilibria and hydrogenation
Olefin isomerization equilibrium and hydrogenation to alkanes

Focused on your needs

Vanguard Catalyst will supply a replacement-in-kind that’s delivered on time, within budget, with no surprises.  Our standard products were designed to be a drop-in replacement for over 80% of the installed market.  The physical and chemical characteristics were chosen to match the most common liquid phase hydrogenation and hydrocarbon oxidation catalysts in use today.

At your request, we will look beyond replacement-in-kind for an improved catalyst formulation.  Vanguard Catalyst helps you address opportunities and issues – by providing not just catalysts, but solutions to problems.

Vanguard’s NIH-210 is a nickel based catalyst for the selective hydrogenation of diolefins to olefins in liquid phase reactors.  Vanguard NIH-210 is designed to be a drop-in replacement catalyst for butadiene selective hydrogenation units with sulfur rich feeds.  NIH-210 is formulated to resist fouling and metal poisoning for extended cycle times between regeneration.

Custom Catalysts

No two liquid phase hydrogenation reactors are the same.  There is an extraordinary range of feed stocks, product specifications, and reactor configurations in today’s hydrocarbon processing industry.  No single catalyst is ideal for all applications and configurations.  A limited product slates requires the operator to conform to the limitations of the supplier.  Vanguard’s catalysts are available in an extraordinary variation of shape, size, physical and chemical properties.

Catalyst size and shape affects catalyst performance because reactor hydraulics matter.  Reactor performance can be improved by switching to other sizes or shapes.  Vanguard stocks carrier in a variety of shapes and sizes.  Many other shapes and sizes are available at your request.

With custom manufacturing, the metal concentration can be selected and controlled from one order to the next, no matter how large or small.  Catalyst performance is influenced by carrier properties, metal content, and the method of metals deposition.  The method of metal deposition for your catalyst is selected based on the performance requirements for your application for your reactor.
