The adsorption properties of carbonaceous adsorbents (such as, activated carbon, biochar, CNTs and carbon⁃silica composites) for VOCs were summarized in this paper. The influence of the structure of adsorbents, the characteristics of VOCs, the humidity and the adsorption temperature were analyzed respectively. The development prospect of carbonaceous adsorbents in the future VOCs adsorption process was proposed. While continuously increasing the adsorption capacity of carbonaceous adsorbented for VOCs, improving the performance of recycling, reducing the impact of high⁃temperature and humidity environments on the adsorption capacity in industrial production was a new trend in the research and development of carbonaceous adsorbents in the future.

        The carbon flow model was established based on Substance Flow Analysis (SFA) and the factors that cause the carbon emission were analysis by mathematical programming. The evaluation indicators were defined in order to evaluate the carbon flowing of TDCS. The results show that the main form of carbon emission is the carbon gases discharged to the environment for TDCS. The main sub-process of carbon emission is the preheating subprocess. And the carbon emission increases with the increasing of fuel consumption and C/H ratio, which influence the carbon emission most.
