“…Among the most pivotal processes, asphalt pyrolysis stands out, holding the promise to convert discarded asphalt into a valuable source of chemicals and energy [3], [4]. Despite its auspicious potential, the inherent challenges of meagre yields and restrained heating values have posed formidable obstacles to the widespread adoption of asphalt pyrolysis [5], [6].In response to this quandary, the integration of catalysts has emerged as a promising avenue for optimizing asphalt pyrolysis processes [7], [8]. Conventional catalysts, particularly those comprising precious metals, have showcased notable efficacy in augmenting yield and enhancing product quality [9], [10].…”

Pyrolysis has proven to be a promising method for converting complex organic materials such as asphalt into high-value products. In an effort to increase the economic efficiency of this process, we investigated the use of non-precious metal nano catalysts for asphalt pyrolysis. Non-precious metal nano catalysts were chosen because of their potential to increase reaction rates and optimize product yields. This research involves the preparation of non-precious metal nano catalysts and their implementation in the asphalt pyrolysis process. The temperature and pyrolysis time variables are varied to determine optimal conditions. The results showed that the use of non-precious metal nano catalysts resulted in a significant increase in the yield of pyrolysis products, with the highest yield reaching 50.78%. In addition, the calorific value of the resulting product also increased to 10684 calories per gram. The main advantage of this research is the emphasis on economic aspects. The use of non-precious metal nano catalysts effectively increases the efficiency of the pyrolysis process, leading to higher product yields and greater calorific values. Thus, the use of non-precious metal nano catalysts makes a positive contribution in reducing production costs on an industrial scale. These findings provide new insights in the development of pyrolysis technology that is sustainable and economical and encourages a wiser use of natural resources through the use of bitumen and other complex organic materials.
