METHOD OF REFINING OF LIGHT FRACTIONS OF SECONDARY ORIGIN |
摘要 |
FIELD: mining. ^ SUBSTANCE: invention refers to method of refining of light fractions of secondary origin consisting in separation of wide benzene spread into light and heavy fractions, and in hydro-upgrading of heavy fraction at raised temperature and pressure in presence of catalyst with successive mixing of light fraction and hydro-upgraded heavy fraction; as wide benzene spread there is used fraction boiled out within C3-220C; light fraction before mixing with hydro-upgraded heavy fraction is subject to sulphur refining by means of extracting with alkali, to successive fractioning and to extracting gas fractions C3 and C4 out of it. ^ EFFECT: upgraded quality of end products due to reduced sulphur contents in gas fractions and in benzene fraction at simultaneous maintaining its octane number. ^ 4 cl, 2 ex |
