A wide range of facilities are available at LSBU.

Batch synthesis of value added chemicals and fuels are conducted in jacketed stirred batch reactor and high pressure (Parr) reactor.

For continuous synthesis of products, we have chromatographic reactor, reactive distillation column (RDC), continuous hydrothermal flow synthesis and FlowSyn continuous flow reactor.

Our analytical facilities include gas chromatography (GC), gas chromatography-mass spectrometry (GC-MS), Trace 1310 gas chromatograph (GC), nuclear magnetic resonance (NMR) and inductively coupled plasma mass spectrometry (ICP-MS).

Continuous reactors used in our research

FlowSyn continuous flow reactor

The need for greener and more sustainable chemical processes has led to significant developments in process intensification, through application of micro reactors/flow chemistry in organic synthesis. The goal is to reduce the size of plants, by replacing large, expensive and energy-intensive equipment or processes, with smaller, less costly and more efficient ones. FlowSyn continuous flow reactors have many advantages, such as reduced reaction times, enhanced safety, reduced solvent usage, lower waste generation, as well as containment of hazardous or unstable intermediates.

Chromatographic reactor (CR)

A simultaneous reaction and separation carried out in a single vessel, also known as a multifunctional reactor, are gaining in interest, as they could be highly feasible. Some chemical reactions which are limited by chemical equilibrium are solved by multifunctional reactors, since the reaction and separation takes place at the same time. An example of a multifunctional reactor is the chromatographic reactor (CR). The CR concept lies in the adsorptivity of the different components involved in the chemical reaction.

Reactive distillation (RD) column

RD is one of the emerging technologies that have extremely attractive potential as a process alternative for carrying out equilibrium limited liquid phase chemical reactions. It is a unit operation which combines simultaneous chemical reaction and multi-component distillation in the same vessel in a single step. RD technology has particular benefit for equilibrium limited reactions. By performing reaction and separation simultaneously, equilibrium can be shifted and in some applications almost complete conversion of the feedstock is economically achieved. RD can also offer heat integration benefits. In the case of exothermic reactions, the heat of reaction replaces some of the energy required for performing the distillation.
