IPEACE223 Vision image


Switching from fossil resources to biomass for realizing carbon neutralization of fuels and chemicals

IPEACE223 Mission image


We can propose ETP (ethylene to propylene) process for catalytic conversion of ethylene derived from ethanol, which is widely used as an additive of automobile fuel. It provides LPG (liquified petroleum gas)-alternative and bio-propylene through the highly selective and cost-effective ways.

IPEACE223 Value image


  • We can provide propylene by the combination of well-modified catalyst affording highly selective conversion of ethylene and well- differentiated regeneration process of deactivated catalyst. We hold highly exclusive IP position.
  • Our technology can realize the drastic mitigation of CO2 emission by providing LPG-alternative and propylene derived from bioethanol as a resource, which can be procured in high volumes.

Activities targeting SDGs





Origin of the company name

Innovative Processes for Eliminating
Anthropogenic CO2 Emission

Two to Three

“Two to Three” – refers to the number of carbon molecules (the “carbon number”) in the chemical reaction that represents the company’s main process for transforming ethylene (carbon no. 2) into propylene (carbon no. 3).
