Dry distillation yemarasha. Imwe yemaitiro akakosha emakambani emarasha emakemikari. Inoreva maitiro ayo marasha anopisa uye kuora ari ega mweya wekugadzira coke (kana semi-coke), marasha tara, isina kuchenesa benzene, gasi remarasha nezvimwe zvigadzirwa. Iyo yakaoma distillation yemarasha shanduko yemakemikari. Zvinoenderana neyakasiyana tembiricha tembiricha, inogona kuganhurwa mumhando nhatu: 900 ～ 1100 ℃ yakanyanya kupisa tembiricha yakaoma, ndokuti, coking; 700 ～ 900 ℃ iri pakati tembiricha yakaoma dhiringi 500 ～ 600 ℃ yakadzika tembiricha yakaoma dhiringi.
