ʻO ka petroleum coke (PET Coke)he huahana ia o ka petroleum coke i hoʻokahe ʻia i nā wela kiʻekiʻe. Hoʻohana ʻia ia i ka hana graphite, ʻoihana hoʻoheheʻe, ʻoihana kemika, a me nā ʻoihana friction.

I loko o nā mea paʻakikī, Calcined petroleum coke (PET Coke)he kuleana nui. No ka loaʻa ʻana o ka PET coke i nā ʻano haʻahaʻa haʻahaʻa a me ka porosity kiʻekiʻe, hana nui ia i ka hana o ka hōʻemi ʻana i ka paʻakikī o ka huahana, e hōʻemi ana i ka walaʻau braking a me ka hōʻemi ʻana i ka palaho wela o nā mea friction i nā wela kiʻekiʻe i nā mea braking.

Hiki iā mākou ke hāʻawi i nā huahana pae like ʻole, hauʻoli hoʻi e hāʻawi i nā huahana i hoʻopilikino ʻia i kā mākou mea kūʻai nui mai ka honua holoʻokoʻa.
