- High-pressure autoclave system
- Mini column on a laboratory scale
- Pilot scale test rig for dual nozzle flow
In our 0.6 L autoclave system (max. 350°C & 350 bar) we conduct biomass liquefaction experiments (e.g microalgae, sludge, bio-waste) and study mechanics and kinetics of different chemical reactions in closed and inert gas atmospheres together with distinct analytics of the reaction products.
The indirectly heated autoclave (Haage/ESTANIT) is made of stainless steel vessel with a barrel gasket and a magnetic stirrer. It is equipped with a cooling coil and can be operated with a eflon or steel liner. Gaseous and liquid samples can be extracted via needle valve connections. Pressure and temperature are electronically controlled and recorded continuously over different pressure ranges (0-350 bar; 0-10 bar etc.)
The composition of gaseous reaction products can be measured by a DX4000 (FTIR) coupled with a heated sample extraction system SYCOS P-HOT for quantitative gas analytics (IR-active gases and O2/H2).
Our mini column (inner diameter 37mm and height 300mm) serves to characterize and get to know material systems. The installation site is under the hood, which guarantees that tests with toxic gases are also possible. Depending on the application, gas analysis is carried out with a FTIR or an IR. For the wet analysis of the liquid phase, a photometer and an automatic titrator are available at the Chair of Process Engineering, respectively, special analyzes are carried out by the accredited laboratory of the Chair AVAW e.g. IC analysis.
This test rig is specifically designed for experimental investigations of atomization processes. The dual fluid system consists of air and water. This nozzle flow test rig enables testing at adjustable conditions, measurement of particle size distribution in jets and slow motion spray imaging.
