Claims (9)

1. Способ уменьшения общего кислотного числа кислой сырой нефти, включающий контактирование сырой нефти с катализатором гидроочистки при температуре примерно 200 - 370°С в присутствии водородсодержащего обрабатывающего газа, содержащего сероводород, при общем давлении примерно 239 - 13900 кПа и мольном содержании сероводорода в обрабатывающем газе 0,05 - 25.1. A method of reducing the total acid number of acidic crude oil, comprising contacting the crude oil with a hydrotreating catalyst at a temperature of about 200 - 370 ° C in the presence of a hydrogen-containing treatment gas containing hydrogen sulfide, at a total pressure of about 239 - 13900 kPa and a molar content of hydrogen sulfide in the processing gas 0.05 - 25. 2.
