有关催化体系 中译英（要求够专业，中国式的自己会）
|
||
|
求助翻译下面这段中文，在论文前言中用，自己写的有点中国化，因此要求要够专业，恳请大家多多指教。 化工生产过程中，80%以上的化学品都要借助于催化技术。一般情况下，在炼油、石化等大宗化学品生产中用的是“多相催化体系”；而精细化学品生产过程中用的多是“均相催化体系”。前者所用催化剂分离、回收利用简便，但操作条件苛刻，反应速度慢；后者虽然反应速度快，条件温和，但催化剂分离、回收利用困难。兼并两者优点并回避各自缺点的催化体系，是众多科学家和企业家共同期盼的目标。 [ Last edited by zhwj on 2009-1-7 at 11:30 ] |

| In the production of the Chemicals, over 80% Chemical Products is by means of the Catalyst Technology. In the ordinary course of events, in the process of infinity Chemicals like oil refining、petrifaction and so on, the heterogeneous catalysis system is used, while in the process of the fine Chemicls, the homogeneous catalysis sysytem is chosed. That is because the catalyzer in the former is easy to separate and recycle, but the operating condition is hard and the reaction velocity is slow. As for the catalyzer in the latter method, though it has the rapid reaction velocity and the operating condition is softness, it is difficult to separate and recycle. It is the common objective for most scientists and enterprisers to find a catalytic system to merger the advantages of the two metheds and avoid their disavantages. |

As catalyst used in the former is easy to separate and recycle, but with harsh operating condition and slow reaction velocity, while that used in the latter, is difficult to separate and recycle though it has rapid reaction velocity and mild operating condition, it has become the common objective for most scientists and enterprisers to find a catalytic system mergering the advantages of both but without their disadvantages. |
