일반 설명

Calcium oxide (CaO) is an alkaline earth metal oxide that has many industrial applications. Calcium oxide receives great attention in catalysis because it is affordable, environmentally friendly, and characterized by a strong basic nature, abundantly available, low methanol solubility and non-toxic compound.

애플리케이션

Calcium oxide is used:
  • As a catalyst during the transesterification of palm oil to produce biodiesel.
  • In the inactivation of Cryptosporidium spp. oocysts and Giardia spp. Cysts from WTS (water treatment sludge).
  • In combination with PAA (peracetic acid) to increases the biogas production potential of cow manure and maize straw.
