Ma ka sulfur maʻamau o ka carburant, hiki ke hoʻokaʻawale i ka sulfur maʻiʻo o ka carburant ma ke ʻano ākea i ka sulfur kiʻekiʻe, ka sulfur medium, ka sulfur haʻahaʻa, ka sulfur ultra-haʻahaʻa.

E pili ana ka sulfur kiʻekiʻe ma luna o 2.0%

ʻO ka sulfur maʻamau e pili ana i ka sulfur maʻiʻo o 1.0% - 2.0%

ʻO ka sulfur haʻahaʻa e pili ana i ka sulfur maʻiʻo o 0.4% - 0.8%

ʻO ka sulfur haʻahaʻa haʻahaʻa e pili ana i ka sulfur ma lalo o 0.05%

ʻO ka hoʻokaʻawale ʻana o ka sulfur maʻamau o nā carburants ma muli o ka ʻokoʻa o ka sulfur maʻiʻo o ke koena i loko o nā ʻano kumu like ʻole a me nā ʻano ʻokoʻa o ke kaʻina hana o ka petroleum coke maka waiwai i ka hana ʻana a me ke kaʻina hana, e alakaʻi ana i ka ʻokoʻa sulfur maʻiʻo o nā carburants.

Eia nō naʻe, i ka hoʻohana ʻana i ka carburizer i nā ʻoihana like ʻole, ʻoi aku ka hopena o ka ʻokoʻa liʻiliʻi o ka sulfur content i ka huahana.ʻO ka laulā wale nō e like me ka sulfur kiʻekiʻe, waena sulfur, haʻahaʻa sulfur carburant maikaʻi mahele ʻaʻole ākea, hiki ke hoʻohana ʻia nā kūlana sulfur carburant ma ke ʻano he kuhikuhi no ke koho ʻana i ka carburant.

ʻO ka mea i luna aʻe he mahele ākea wale nō o ka carburizing agent sulfur standards, kikoʻī i ke koho ʻana i ka carburizing agent, ʻo ka sulfur content kahi mea hōʻailona koʻikoʻi, ua ʻōlelo ʻia e koho i nā mea hana ʻoihana.
