1. Methods of studying coke formation
Sammanfattning : .... LÄS MER
2. Coke on Supported Palladium and Platinum Catalysts
Sammanfattning : Catalyst deactivation by coke formation has been investigated in three heterogeneous catalytic processes, propane dehydrogenation, acetylene hydrogenation and hydrogenation of vegetable oil. Palladium and/or platinum supported on alumina were used as catalysts in all reactions. LÄS MER
3. Catalyst Deactivation by Coke Formation in Acetylene Hydrogenation
Sammanfattning : Several aspects of catalyst deactivation have been studied with reference toselective acetylene hydrogenation, a reaction used industrially to purify ethylene from unwanted acetylene. A mathematical model has been developed for an industrial packed-bed reactor, employing a supported Pd catalyst. LÄS MER
4. Influence of the properties of bio-coal as a substitute for fossil coal in carbon composite agglomerates and in coke
Sammanfattning : The iron-ore-based blast furnace (BF) process is still the most dominant method for producing metallic iron units for steelmaking, and the BF is also the main contributor to the 7-9% of global CO2 emissions which, according to World Steel Association, originate from the steel industry. The steel industry is aiming to reduce CO2 emissions by different means. LÄS MER
5. Evolution of coke properties while descending through a blast furnace
Sammanfattning : Due to increasing price and economic pressures, there is a need to minimise coke consumption. The lesser amount of coke used has indirectly set higher standards for coke quality and led to a wish for even more knowledge about its function in the blast furnace. LÄS MER
