Resumen: Hydrogen and liquid fuel production from biopolymer waste, such as cellulose dissolved in phenol, was investigated using in-situ pyrolysis-catalytic steam reforming conditions. Developing a sustainable method for the thermal cracking of such biopolymers still faces difficulties due to the catalyst stability primarily impacted by coke deposition. The key to the proposed method is improving a highly active and stable catalytic reforming process in which trimetallic Ni-La-Pd supported on TiCa acts as a primary reforming catalyst. Catalysts were prepared by hydrothermal, and impregnation techniques, and the physicochemical characteristics of the fresh and spent materials were examined. The results showed that the NLP/TiCa catalysts performed effectively due to their comparatively high surface area, strong basicity, evenly distributed Pd particles, and appropriate redox and desorption characteristics. The addition of Pd retards the reducibility of the NL/TiCa; therefore, a Pd∗La, La∗Ni, La∗Ti, and Ca∗Ti interaction exist. Almost complete conversion of phenol (98.7%) and maximum H2 yield (99.6%) were achieved at 800 °C for the NLP/TiCa. These findings give an insight into industrial-scale development. They have significant potential for enhancing the generation of hydrogen and liquid products from phenol and cellulose waste, such as propanol, ethanol, toluene, etc.
