TGA / STA HP 3

High Pressure Thermogravimetric / Simultaneous thermal analysis instrument

Description

On point

Linseis introduced the all new TGA/STA HP3 table top high pressure thermogravimetric, simultaneous thermal analysis instrument. The TGA/STA HP 3 is the result of 25 years of experience thermal analysis under high pressure. The superior high speed micro-furnace with a maximum temperature of 1200°C, top loading microbalance, true TG-DSC Thermogravimetry-differential scanning calorimetry design permit exiting new opportunities. The table top design, optional vapor generator and different gas dosing systems provides utmost flexibility.

Worlds only top loading combined TG-DSC Thermogravimetry-differential scanning calorimetry. For experiments up to 1200°C and up to 150 bar in reactive or inert atmospheres.

Easy user exchangeable TGA or TG-DSC plug and play sensors. The right choice for any given experiment gives you the flexibility to analyze TGA only experiments with volumes up to 1 ml or combined TGA-DSC analysis with up to 0.12 or 0.3 ml volume.

TG-DSC Thermogravimetry-differential scanning calorimetry arrangement permits the combined analysis of weight change and caloric events like endothermal or exothermal reactions or phase transitions in one run and under the same temperature, gas and pressure conditions.

High accurate sample temperature measurement. The thermocouple is in direct contact with the sample. The configuration of the TGA/STA HP 3 eliminates temperature measurement errors due to sample – thermocouple distance (unlike levitating MSB-Magnetic Suspension Setup).

High speed micro heater permits rapid heating and cooling (up to 300°C/min controlled heating rate and up to 150°C/min cooling rate).

Very small furnace volume allows rapid gas changes. In addition the low volume lowers the cost of ownership (gas consumption/energy requirement) drastically.

Flexible gas dosing and security design. Our gas dosing panels can be designed to your needs. The number of gases can be selected (standard up to 3, more on request). In addition an optional vapor generator as well as an automatic evacuation and gas burn off safety system for gases like hydrogen and hydrocarbons are available.

Applications

Application: Coal gasification

A common known application for HDSC measurements is the investigation of the so called coal gasification or hydro gasification. This process, where carbon is heated in a water steam atmosphere is used in some catalytical processes, for example to remove carbon monoxide (CO) from exhaust fumes and especially to get valuable organic compounds out from resources like charcoal or biomass.

The whole process can be described like this:

Charcoal or the Carbon parts of Biomass react with water vapour to a mixture of carbon monoxide and hydrogen at higher temperatures (C + H2O CO + H2).

This process can be done with or without additional oxygen. If an oxygen containing atmosphere is used, you will also get additional carbon monoxide according to (C + O2 CO2 followed by C + CO2 2 CO) The third equation, no matter if you use oxygen or not, shows the reaction of carbon monoxide with water to get more hydrogen (CO + H2O CO2 + H2). So in the end you will get a mixture of carbon monoxide and hydrogen.

Those two gases are involved in chemical balances and therefore sometimes it is also interesting, to know how much pressure you have in your system, because the pressure determines on which side of the equation the balance will be. Finally, the purpose of the coal gasification is, that you can get methanol and methane out of the two created gases carbon monoxide and hydrogen (CO + 2 H2 CH3OH; CH3OH + H2 CH4)

That means with this process you can get from any kind of carbon to the basic building block of almost every organic compound (drugs, polymers, oils, waxes, fatty acids, organic acids and so on).
