摘要:

概述了近年来国内催化裂化（及其家族）装置轻柴油质量状况及存在的主要问题。该技术家族装置的干气中含有一定数量的氢气，用膜分离新技术将干气中氢气回收后，进行催化裂化（及其家族）装置轻柴油加氢精制，既解决了柴油质量问题，又节约了炼油厂（石油化工厂）的投资和能源。

Abstract:

The quality state and the existing problems of light diesel oil from domestic cataytic cracking insallation are briefly reviewed. The dry gas from these insallations contains a certain amount of hydrogen. The hydrogen recovering from dry gas by membrane s
