PPT-Catalysts

Things that Effect Rate Catalysts substances that speed up a reaction without being used upenzyme Speeds up reaction by giving the reaction a new path The new path has a lower activation energy. Per Zeuthen Haldor Topse AS Copenhagen Denmark The latest diesel and gasoline specifications require reducing sulphur to very low concentrations The FCC unit is the major source of gasoline in a FCC refinery however the sulphur content of the FCC pr acid to stearyl alcohol 2.1. Chemicals and Catalysts All chemicals were of AR grade and used carboxylic acids and dodecane were procured from Sigma-Aldrich. High purity Hwas obtained from BOC. Pt and Grand Challenges Summit.

Baseline (Flightpath D): To be able to define the terms ‘catalyst’ and ‘enzyme. ’.. Further (Flightpath C&B ): To be able to describe the properties of enzymes. To use the lock and key theory and collision theory to explain enzyme action. CATALYSTS AND ENZYMES. What are catalysts?. Simply put, catalysts are substances which, when added to a reaction, increase the rate of reaction by providing an alternate reaction pathway with a lower activation energy (Ea).. ROGER S CONRAD.
