ʻO wai ka Papa Pahū-Hōʻoia i ʻoi aku ke kiʻekiʻe, AT3 a i ʻole BT4

Ma nā māhele kinoea a me ka wela, ʻOi aku ka BT4 i ka AT3, no laila e hāʻawi ana i kahi helu pahū-hōʻike kiʻekiʻe.

Aia ka papa A i nā kinoea e like me ka ethane, methanol, ethanol, a me ka ʻaila; Aia ka papa B i nā kinoea e like me ke kinoea noho, ethylene, a me ka ethylene oxide.

Hoʻopili ka hoʻohālikelike ʻana o ka wela T3 i nā kaiapuni a hiki i 200 ℃ a komo pū 36 nā kinoea maʻamau e like me ka ʻaila a me ka butyraldehyde. Hoʻopili ka hoʻohālikelike T4 i nā mahana i 135 ℃, no hoi 36 nā kinoea me ka acetaldehyde a me ka tetrafluoroethylene.
