摘要：Design of catalytic materials has been highlighted to build ultraclean use of heavy oil including liquid-to-gas technology to directly convert heavy hydrocarbons into H₂–rich gas fuels. If the H₂ is produced from such heavy oil through high-active and durable catalysts in reforming process that is being constructed in hydrogen infrastructure, it will be addressed into renewable energy systems. Herein, the three different hollow fiber catalysts networked with perovskite nanoparticles, LaCr_0.8Ru_0.2O₃, LaCr_0.8Ru_0.1Ni_0.1O₃, and LaCr_0.8Ni_0.2O₃ were prepared by using activated carbon fiber as a sacrificial template for H₂ production from heavy gas oil reforming. The most important findings were arrived at: (i) catalysts had hollow fibrous architectures with well-crystallized structures, (ii) hollow fibers had a high specific surface area with a particle size of ≈50 nm, and (iii) the Ru substituted ones showed high efficiency for H₂ production with substantial durability under high concentrations of S, N, and aromatic compounds.
