Problem 1: Exothermic reaction in a jacketed continuous stirred tank reactor. 100 points. You need to carry out a reaction A → B in a continuous stirred tank reactor (CSTR) in a chemical plant. Before you perform this reaction in a CSTR, you need to determine the equation for the rate of the reaction.
The majority of the commercially available biodiesel, one of the most promising biofuels, is made by the trans-esterification of vegetable oils and animal fats with methanol or ethanol in stirred-tank reactors in the presence of base or acid catalysts ; nonetheless, these reactors are often used for batch production, creating the demand for .
batch, plug flow, fixed bed or continuous stirred-tank reactors. Batch reactor for commercial biodiesel production is not recommended because of its tedious mode of operations [5]. Thus, plug flow reactors, CSTR and fixed bed reactors are more viable to be used in commercial biodiesel production.
Oscillatory flow reactors offer a number of advantages over conventional reactors such as flow plug reactor (FPR) and continuous stirred tank reactor (CSTR). The flow patterns in an oscillatory baffled reactor operating at oscillating conditions show a high extent of radial mixing, which can be used to control the residence time distribution in .
Nov 15, 2019 · A new transesterification reactor, operating in continuous mode, has been designed, made and tested experimentally in order to produce a biodiesel from rapeseed oil. This reactor is an alternative solution to the batch system existing in the industry. It is composed of three-dimensional serpentine geometry (S-3D). The flow in this geometry is laminar, Reynolds number is less than 360.

The aim of this paper is model the continuous Oscillatory Baffled flow Reactor for biodiesel production from Jatropha oil. It presents the prediction of the number of serially arranged ideal stirred tank reactors (N), that will have an equivalent performance as an Oscillatory baffled flow reactor using Tanks –in-Series Model approach.
The continuous reactor for transesterification of refined palm oil with methanol was designed and tested. The reaction condition was focused at ambient pressure, temperature of 60ºC, molar ratio of alcohol to oil of 6:1, and NaOH of 1.0 %wt of oil. The designed reactor was in a form of a 6-stage mechanically stirred tank.

Continuous stirred-tank reactors (CSTRs) are open systems, where material is free to enter or exit the system, that operate on a steady-state basis, where the conditions in the reactor don't change with time. Reactants are continuously introduced into the reactor, while products are continuously removed.
