Yeyiphi eneNqanaba eliPhakamileyo lokuBonelela, BT4 okanye CT4

Ukuhlelwa kobungqina bokudubula kwezixhobo ze-CT4 zodlula ezo ze-BT4.

I-BT4 ihlelwa njengeqela lobushushu beKlasi B, apho ubushushu obuphezulu bomgangatho wezixhobo ezilinganiswe nge-T4 bungadluli kwi-135 ° C. I-CT4 inomlinganiselo wobungqina bokudubula kwiKlasi C, ithelekiseka ne-BT4, kwaye ilungele iindawo ezinerhasi ezinobungozi ezifana ne-hydrogen kunye ne-acetylene, ukugcina ubushushu obuphezulu bomphezulu be-135°C.

Ubungakanani bosetyenziso

I-BT4 ifanelekile kwiigesi eziqhelekileyo kuquka i-methane, ethane, i-petroleum, kwaye ihydrogen i-sulfide.

I-CT4 ibandakanya uluhlu olubanzi lwezinto ezingaqhelekanga qhuma iigesi, njenge-hydrogen kunye negesi yamanzi kwinqanaba le-CT1, i-acetylene kwinqanaba le-CT2, kunye ne-carbon disulfide kwinqanaba le-CT4.
