Abstract:

Usually，in chemical process，the products are obtained through multi-step chemical reactions.Integration 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 multi-step chemical reactions.
