- Abstract
- Catalytic pyrolysis has been considered as one of the most effective methods for processing light C hydrocarbons. In this study, a Ni−Sn catalyst was synthesized using mechanochemical alloying, and the influence of temperature (in the range of 600–750°C) on the decomposition of C−C alkanes into a carbon nanomaterial was investigated. The Ni−Sn system demonstrated a high carbon yield exceeding 300 g/g at T > 710°C. The calculated value of the apparent activation energy of reaction was 140 ± 5 kJ/mol. The effect of reaction temperature on the morphology, structure, and textural characteristics of produced carbon nanomaterial was explored. Regardless of the process temperature, the product consisted of nanofibers with thickness ranging from 5 to 100 nm. The obtained material exhibited a significant specific surface area (up to 450 m/g) and high pore volume (up to 0.80 cm/g).
