Naphha, lub teeb roj muab tau los ntawm cov roj nyoos los ntawm cov roj av nyoos lossis lwm cov ntaub ntawv nyoos, feem ntau yog paub txog tshuaj lom neeg lub teeb alkylate. Nws ua haujlwm ua qhov tseem ceeb rau cov khoom siv tshuaj lom neeg hauv ntau yam kev lag luam. Naphtha cov distillation ntau yuav sib txawv raws nws siv. Raws li Suav cov qauv, thawj zaug boiling taw tes yog feem ntau nyob ib ncig ntawm 220 degree.

Thaum siv raws li cov pub rau ethylene ntau lawm los ntawm kev tawg, distillate ntawm 70 degree thiab 145 degree tau cais raws li lub teeb Naphha. Rau kev tsim cov tshuaj tua kab mob lossis qib hos-octane octoline, qhov feem ntawm 70 degree thiab 180 degree tau txiav txim siab ib txwm naphha. Thaum ua haujlwm raws li cov kuab tshuaj, nws tau raug hu ua cov kuab tshuaj naphtha.
