Abstract

Cement kiln co-processing (CKC) is a promising technology for solid waste treatment, which can achieve both goals of energy saving for cement production and environment protection for waste reduction, and further development of this technology is desired, so it is necessary to highlight its research gaps between science and technology. In this study, a framework for identifying technological opportunities of cement kiln co-processing was proposed, where (1) scientific and technological keywords from papers and patents were extracted through the RAKE algorithm, and these keywords were divided into four clusters: effect, technology process, object of co-processing and pollutant; (2) the semantic similarities between the cluster science and technology fields were analyzed by calculating their cosine similarity of vectors to determine the technological opportunities, which combined with the occurrence time and frequency of the selected keywords. The results show that the cluster “effect” technologies have been almost developed. In the other three clusters, several technologies are more likely to become technological opportunities for CKC: power generation from recovered heat, co-processing of sludge and raw meal, heavy metal, and NOx emission control. This work provides guidance information for policy research and future studies about CKC.
