Abstract
As the hydrogen economy is coming soon, the development of an efficient H2 production system is the first issue to focus on. In this study, a first attempt to utilize light cycle oil (LCO) feedstock is introduced for H2 production through autothermal reforming (ATR) using perovskite catalysts. From a careful characterization, it is found that LCO possesses a high content of C–H and S/N compounds with over 3–4 ring bonds. These various compounds can directly cause catalyst deactivations to lower the capability of H2 extraction from LCO. To achieve a heteroatom resistance, two different perovskite micro-tubular catalysts are designed with a Ru substitution at the B-site. The activity and stability of the Ru doped perovskite were controlled by modifying the Ru electronic structure, which also affects the oxygen structures. The perovskite with a B-site of Cr reveals a relatively high portion of active Ru and O, demonstrating an effective catalyst structure with a comparable LCO reforming activity at the harsh ATR reaction conditions. The greater stability due to the Ru in the perovskite is investigated post-characterization, showing the possibility of H2 production by LCO fuel through the perovskite catalysts.
Highlights
The high demand for a new energy source has risen for many years, due to the limited amount of carbon-based sources that cause severe environmental pollution by combustion [1,2]
Agreement was agreed under the United Nations Framework Convention on Climate Change (UNFCCC) between over 190 countries to be prepared for the severe climate change [3,4,5]
When we look closely on the fiber surface, it was smooth and clear due to a light carbon coverage after the light cycle oil (LCO)-autothermal reforming (ATR)
Summary
The high demand for a new energy source has risen for many years, due to the limited amount of carbon-based sources that cause severe environmental pollution by combustion [1,2]. Agreement was agreed under the United Nations Framework Convention on Climate Change (UNFCCC) between over 190 countries to be prepared for the severe climate change [3,4,5]. The goal of this agreement is to limit the global warming to 2 ◦ C (and even 1.5 ◦ C) at above pre-industrial levels by. A huge demand for hydrogen has recently increased, due to the expansion of the hydrogen-based society
