5-2- LABORATORY GAS-LIQUID-SOLID REACTORS 5-2-1 Differential Reactor 

This type of reactor is very widely used because it is one of the simplest to construct and it is cheap. Sampling and analysis of the product streams are generally easy, but they can be difficult to obtain effectively at low conversions. Isothermality of the reactor is generally attainable, particularly at low heat release. Residence-time distribution measurements can be difficult because of channeling problems, but this can be somewhat reduced by running the reactor vertically rather than horizontally. 

When using a differential reactor in complex reaction systems, synthetic feeds must be prepared which match the composition at various stages of conversion. 

Integral reactor data are intrinsically more accurate than differential reactor data. 

Data at high conversion are usually preferred in discriminating statistically between possible rate models.
