'Catalytic propane dehydrogenation is the most important alternative route to propylene, the world’s second largest petrochemical commodity. We will study this reaction over novel bimetallic Pt-Ga catalysts which demonstrate improved resistance to coking. Specific research objectives of the project are: 1) perform a comprehensive investigation of propane dehydrogenation over the Pt-Ga catalysts, including the main catalytic cycle, side-reactions, and deactivation pathways, 2) determine how gallium doping and its method of introduction to platinum control catalytic properties, and 3) formulate and validate a microkinetic model suitable for describing the propane dehydrogenation reaction over the Pt-Ga catalysts under realistic operating conditions. We will employ advanced experimental techniques of transient kinetics and operando spectroscopies to study intrinsic reaction kinetics over a wide pressure range, linking detailed molecular mechanisms elucidated at low pressure to catalyst performance at industrially relevant atmospheric pressure. The project will include development of an extended Temporal Analysis of Products (exTAP) methodology for a systematic kinetic characterization of both technical and model catalysts which will have a broad scientific impact by providing a general strategy for bridging the 'pressure gap' in catalytic research.'
Researchers have furthered our understanding of catalyst behaviour during an important industrial reaction: propane dehydrogenation to form propylene.
Platinum-based catalysts are used for a wide variety of industrial processes involving hydrocarbons. Unfortunately, the efficiency of these catalysts is affected by the build-up of unwanted carbon deposits known as coke.
The EU-funded 'Intrinsic catalytic kinetics analysed and reconciled with industrial conditions' (ICKARUS) project aimed to study the behaviour of novel platinum (Pt) catalysts during the propane dehydrogenation reaction process.
Project members studied Pt nanoparticle catalysts promoted by gallium, tin or indium atoms. These were shown previously to have improved resistance to coking (build-up of a type of carbon), making them ideal subjects for further study and exploitation.
Researchers also found that bi-metallic catalysts had better overall catalytic performance due to certain active sites being blocked by carbon deposits. They also improved understanding of how alloys form on the catalyst surface under certain conditions.
Lastly, ICKARUS deployed a Temporal Analysis of Products instrument, using it to study the catalysis of propane dehydrogenation. This is a technique that measures a range of physical characteristics of a reaction process.
These insights will inform innovations geared towards improving industrial catalysis, thus helping to boost global industry.
