Low Temperature Catalyst

lec 04Our low temperature catalyst, LTC, can catalyzes oxidation of mercaptans and hydrogen sulfide, which are extremely odorous in living environment at room temperature. VOC including Formaldehyde, which is known as possible source for sick house or sick office syndrome, can be removed by LTC.


Typical applications Deodorant filter for home appliance, VOC removal filter for copy machine and etc
Typical product shape Honeycomb monolith or non-woven mat
Product code LTC


  • Excellent performance in removal of odors at room temperature
  • Low pressure drop

Typical Applications

  • Air purifiers
  • Air conditioners
  • Refrigerators
  • Toilets
  • Other deodorization

Deodorization / Partial oxidation by LTC

ltc 06

LTC can partially oxidize sulfur compounds such as methylmercaptan and hydrogen sulfide at room temperature and reduce the odor drastically. Methylmercaptan is partially oxidized by LTC into dimethyl disulfide, whose olfactory threshold is approximately 30 times as high as that of methylmercaptan; its chemical reaction formula is as follows.

Partial oxidation of methylmercaptan

2CH3SH + 1/2O2 → CH3-S-S-CH3 + H2O
