In this chapter, residence time distribution (RTD) of ideal and nonideal reactors along with the method of determination are described in detail. The influence of nonideality and RTD on the reactor performance, the target product yield, and selectivity, including complex reactions, is presented....
3) RTD 停留时间分布 1. In this paper,the residence time distribution(RTD)of fluid in jet- entrained bed reactor is measured with pulse induction of sample,factors which influencing RTD are also investigated. 本文使用脉冲进样法测定了气流喷射床反应器液体的停留时间分布(RTD),并用Fluent软件模拟...
A computer simulation framework is developed for modeling the residence time distribution (RTD) of integrated continuous downstream processes based on a unit-by-unit modeling approach in which unit operations are simulated one-by-one across the entire processing time, and then combined into an ...
ExtruVis is an instrument to measure Residence Time Distribution (RTD) in any possible application in which a visual tracer can be applied. After adding the tracer, ExtruVis records a video of the experiment. Once the measurement is completed, ExtruVis evaluates the RTD automatically. Tracer + ...
The determination of the local residence time distribution (RTD) in a co-rotating twin screw extruder was performed using a UV tracer method. This method was used to test the RTD response to a pulse input into the different elementary screw elements such as right- and left-handed screw ...
Based on some experimental investigations of liquid phase residence time distribution (RTD) in an impinging stream reactor, a two-dimensional plug-flow dispersion model for predicting the liquid phase RTD in the reactor was proposed. The calculation results of the model can be in good agreement ...
