中文摘要：
在化工生产过程中，通常需要多步化学反应才能获得目标产物。为了最大限度地节约能源、提高资源利用率和减少排放，多步反应过程集成是重要途径。通过对化学反应过程集成系统的分析，基于不同催化剂活性相的组合尺度，提出将多个催化反应构成的系统划分为纳米尺度、微米尺度和宏观尺度3类绿色集成系统，并通过典型实例进行了论述。认为催化剂活性相以纳微尺度复合的多功能催化剂是实现多步反应一步化的有效方法之一。
英文摘要：
Usua reactions. Integr lly, in chemical process, the products are obtained through multi-step chemical ation of the multi-step reactions is a matter of great importance for saving energy, improving utilization of resource and cutting down the emission. In this paper, based on the combination scale of the different catalytic active sites, the integrated system, which is composed of several catalytic reactions, is divided into three sub-systems： nano-scale, micro-scale and macro-scale. The typical examples are discussed separately. It was considered that the multi-functional catalysts, in which the active sites were combined in nano/micro scale, was one of the promising methods for the integration of multistep chemical reactions.
