D-1275 Sulfur Sorbent

BASF's D-1275 is a commercially proven, extruded nickel sorbent that is effective in trapping small amounts of sulfur compounds not removed in upstream hydrodesulfurization processing. It protects downstream catalytic reactors that are affected by sulfur contamination, such as naphtha reformers, by adsorbing H2S and all other sulfur species, including mercaptans and thiopenes.

Precious metal reforming catalysts, especially those with a high rhenium to platinum ratio, can benefit greatly when feed sulfur is consistently reduced to less than 0.1 ppm. Benefits include greater cycle and ultimate life, along with improvements in activity and yields. Additionally, D-1275 provides insurance against premature shutdown of the reformer by acting as a guard against unexpected breakthrough during upsets to the upstream hydrodesulfurizer.

D-1275 is supplied in a reduced and stabilized form. It is offered as a quadrilobe extrudate to maximize geometric surface area thus offering maximum sulfur pick-up per pound with reduced pressure drop across a fixed-bed reactor.

Typical properties of D-1275 are:
  • Chemical composition, wt % nickel
  • Nominal average diameter, inches (mm)
  • L/D
  • Density, lbs/ft3 (kg/m3)
