The catalytic pyrolysis is one of the thermochemical patterns for producing chemical products consisting of solid char, liquid oil, and pyrolytic gas. A number of parameters affecting the catalytic pyrolysis process, yields, and properties of products such as the temperature, residence time, heating rate, feedstock type, and the use of catalyst were evaluated in details to promote the process of catalytic pyrolysis. Catalytic pyrolysis has emerged with the use of a catalyst such as red mud, fly ash, copper slag, blast furnace slag, coal gangue, and aluminum dross. In this paper, a brief discussion with recent development on industrial solid wastes as a catalyst in catalytic pyrolysis process is presented. In the process, the liquid oil is of higher quality; in addition, process by-products such as solid char can be used as an adsorbent material, while the quality of pyrolysis gases is improved. Despite all the potential advantages with industrial solid wastes as a catalyst, some limitations such as less reuse of catalyst and high parasitic energy demand are still remaining. The recommended measurements for these challenges include exploration of suitable reactor, catalyst regeneration, and catalytic mechanism optimization.
