Hydrocracking Test Tube Reactor

For any request, please refer to service.weigand(at)chemie.tu-dresden.de

The Hydrocracking reactor is equipped with three gas inlets for hydrogen, nitrogen and air, all equipped with a continuous flow controller. The gas streams can be varied between 0 - 340 ml/min concerning hydrogen or nitrogen and 0 - 170 ml/min concerning air. Additionally, a liquid educt can be dosed by a syringe driver capable of a maximum pressure of 25 bar. The steel reactor can maintain a reaction pressure from 1.5 - 20 bar and is embedded in a vertically mounted furnace capable of temperatures up to 650 °C. The gaseous product stream is connected to the gas chromatograph. Liquid products are collected in a seperator. Catalyst volumes between 0.5 - 5 ml may be tested.

The Hydrocracking reactor can be used to perform catalytic tests in a tubular reactor. The catalyst sample is usually a fine-particle granulate with particles in the range 315 - 400 µm. The tubular reactor can be fed simultaneously with two gas streams of three different gases and a liquid educt. The liquid educt will be evaporated at the reactor inlet. The gaseous products are analyzed online by gas chromatography.
