1. Kufotokozera Zamalonda:

Mafuta a petroleum opangidwa ndi sulfure yapamwamba kwambiri ndi yakuda kapena yotuwa kwambiri, yokhala ndi zitsulo zonyezimira, zonyezimira, zopangidwa ndi graphite yaying'ono yopangidwa ndi granular, columnar kapena singano ya carbon body.Gawo la mafuta a coke ndi hydrocarbon, yomwe ili ndi 90-97% carbon, hydrogen 1.5-8%, ilinso ndi nayitrogeni, chlorine, sulfure ndi mankhwala olemera a zitsulo.

Mafuta a coke amapangidwa pamene mafuta osaphika a coking ochedwa aphwanyidwa pa kutentha kwakukulu kuti apange mafuta opepuka.Kupanga kwa petroleum coke ndi pafupifupi 25-30% ya mafuta osaphika.Mtengo wake wochepa wa calorific uli pafupi ndi malasha 1.5-2 nthawi, phulusa siliposa 0,5%, zosakhazikika zimakhala pafupifupi 11%, khalidwe pafupi ndi anthracite.

2. katundu ndi ntchito:

Mkulu wa sulfure calcined petroleum coke amagwiritsidwa ntchito makamaka popanga zinthu za carbon, monga graphite elekitirodi, anode arc, kupereka zitsulo, zitsulo zopanda chitsulo, zitsulo zotayidwa;Kupanga zinthu zopangidwa ndi silicon, monga mawilo osiyanasiyana opera, mchenga, pepala la mchenga, ndi zina zambiri;Kupanga malonda a calcium carbide kuti apange ulusi wopangira, ethyl kudya ndi zinthu zina;Itha kugwiritsidwanso ntchito ngati mafuta.
