The main methods of treating oily sludge at home and abroad and the current research status of oily sludge pyrolysis technology are briefly described, and four commonly used catalysts are introduced: metals, metal compounds, molecular sieves, metal-supported molecular sieves, and biomass catalysts for oily sludge. The influence of pyrolysis, the pyrolysis mechanism, and the product composition of oily sludge with the addition of different catalysts are also discussed. Finally, the development direction of preparing new catalysts and the mixed use of multiple catalysts is proposed as a theory to provide for the efficient and reasonable utilization of oily sludge.

Word Clustering

In order to profile the research status of carbon nanotubes (CNTs), and gasp the development direction of the subject, based on the database of INSPEC, with the help of INSPEC thesaurus, using co-word clustering, 8 important subfields of CNTs are identified in this paper. Furthermore, the trends of each subfield with time was showed as well as the journal distribution of each subfield was analyzed. The result should be focused on to provide the institutions, researchers and decision makers of CNTs with useful reference.
