CDS high pressure and catalyst mini reactor systems - new for 2010

Scientists studying new material, such as various biomass feed stock, coal or polymer reactions need to understand how these materials break down in a reactor at varying conditions often with a catalyst. The high-pressure pyrolyser system allows the study of both high temperature & pressure on a small scale in the lab before undergoing the time and expense of scaling up to a pilot reactor. In addition the mini reactor system utilises a catalyst bed of the users choice. The systems use the model 5200 pyroprobe that has been modified with a back pressure regulator to the analytical trap. Samples can then be pyrolysed at elevated pressures (500psi max) and collected onto the built-in trap. After pyrolysis of the sample is complete, the analytes are transferred to the GC at normal operating conditions.The unique interfacing design permits a direct pyrolysis path to the GC inlet or rapid sample heating and transfer to the trap without interrupting the pneumatics of the GC Any reactant gas can be used including H2, O2, CH4 or CO in the pyrolysis chamber.
