Dry reforming of methane is a very appealing catalytic route biogas (mainly composed by greenhouse gases: carbon dioxide and methane) conversion into added value syngas, which could be further upgraded to produce liquid fuels chemicals. However, the major culprits this reaction are coking active phase sintering that result in catalysts deactivation. Herein we have developed highly stable bimetallic Ni–Rh catalyst supported on mixed CeO2–Al2O3 oxide using low-noble metal loadings. The...
Biofuels upgrading gathering momentum in view of the gradual depletion fossil fuels and pursuit renewable energy sources to mitigate global warming. Hydrodeoxygenation (HDO) is a key reaction bio-oil produce hydrocarbon or high-value chemicals. Oxygen removal increases its calorific value, improve thermal chemical stability, reduce corrosiveness, etc., making upgraded suitable as fuel blending fuel. However, dependence on high-pressure hydrogen serious disadvantage, it an expensive resource...
Designing dual function materials (DFMs) entails an optimisation of CO2 adsorption and catalytic conversion activity, often requiring a large number experimental parametric studies screening various types loadings of...
Nickel phosphide catalysts show a high level of selectivity for the reverse water-gas shift (RWGS) reaction, inhibiting competing methanation reaction. This work investigates extent to which suppression can be controlled by phosphidation and tests stability phases over 24-hour time on stream. Herein synthesis different crystal structures varying Ni/P atomic ratios (from 0.5 2.4) is shown affect CO CH4 in significant way. We also that activity these fine-tuned ratio identify suitable low...
Integrated carbon dioxide capture and utilization (ICCU) technology is being developed to address the challenge of increasing atmospheric CO2 levels. Dual function materials (DFMs) are designed with catalytic adsorbent components that enable within a single reactor. In this investigation, we systematically evaluated performance NiRu-DFMs incorporating oxides Ca, Na, or combination identify effects on both activity selectivity. Our findings underscore not only role selection in dictating...
