General description

Ascarite® consists of sodium hydroxide-coated silica. It is a carbon dioxide adsorbent.

Application

Ascarite® was employed as CO2 trap for the following studies:
  • Catalytic conversion of biomass-derived feedstocks into olefins and aromatics system.
  • Catalytic conversion of furans in the continuous flow fixedbed reactor.
  • Catalytic testing of the zeolite samples for conversion of glucose and maple wood using a semi-batch Pyroprobe reaction system.
  • Isotopic analysis of methane (CH4) samples by near-infrared (NIR) continuous-wave-cavity ring-down spectrometry (CW-CRDS).

Packaging

100, 500 g in poly bottle
