Inert Ceramic Ball BSM-900

Alumina Ball BSM-900

The monolith structure eliminates in-service spalling and delamination, which prevents the occurrence of fine chips and splinters.
Maximum resistance to erosion and low attrition minimizes the possibility of catalyst contamination.
High thermal shock resistance.

Applications for BSM-900:

  • Ammonia production: herewith temperatures can reach 1250℃ with pressures as high as 3500kpa.
  • Methanol and hydrogen production: primarily reforming.
  • Alkylation process using hydrogen fluoride at high temperatures.
  • Naphtha reforming.
  • Isomerization.

Thermal shock resistance test for BSM-900

  1. Randomly pick 100 particles of BSM-900 from the batch or shipment.
  2. For each sample selected, heat it up to 1100℃ and maintain them at this temperature for 30 minutes.
  3. Drop the hot balls into cold 20℃ water.
  4. Repeat steps two(2) and three(3) ten times on each and every ball in the sample lot.
  5. Examine the balls on clear signs of breakage and /or cracking. Our standard goal is that all the balls remain intact.
