Escaping undesired gas-phase chemistry: Microwave-driven selectivity …
WebSep 12, 2013 · A number of techniques have been used to control reaction selectivity by the use of surface modifiers. Carbon monoxide is well known as a surface poison that can reduce surface ensemble size to ... The three properties are found to be: The property holds. In this reaction, 90% of substance A is converted (consumed), but only 80% of the 90% is converted to the desired substance B and 20% to undesired by-products C. So, conversion of A is 90%, selectivity for B 80% and yield of substance B 72%. See more Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering. They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and … See more Yield in general refers to the amount of a specific product (p in 1..m) formed per mole of reactant consumed (Definition 1 ). However, it is also defined as the amount of product produced … See more For batch and continuous reactors (semi-batch needs to be checked more carefully) and the definitions marked as the ones generally found in the literature, the three concepts can be combined: $${\displaystyle Y_{p}=X_{i}\cdot S_{p}}$$ For a process with … See more The following assumptions are made: • The following chemical reaction takes place: where See more Conversion can be separated into instantaneous conversion and overall conversion. For continuous processes the two are the same, for batch and semi-batch there are … See more Instantaneous selectivity is the production rate of one component per production rate of another component.
