有机废气催化燃烧过程中多尺度效应和催化剂设计
Multi-scale effect and catalyst design in catalytic combustion of organic waste gas
摘要
Abstract
Catalytic combustion of heavy air polluting organic waste gases over supported noble metal catalysts has been in extensive study and application, due to high removal efficiency and absence of secondary pollution.However, current technology still suffers from various problems such as high energy consumption and cost.There is a strong correlation between combustion efficiency of organic waste gases and dimensional structures of catalysts so that a multi-scale effect exists from microscopic active sites to catalyst and catalyst bed.A comprehensive consideration of function enhancement and design optimization by catalyst functions at each scale level is an effective way to improve removal efficiency of the supported noble metal catalyst.This review summarizes recent domestic and international design strategy and output with consideration of the multi-scale effect in catalytic organic waste gas combustion system, and provides a prospect for future research direction of organic waste gas combustion catalysts.关键词
