FINESORB-3010 is the newest automatic catalyst characterization instrument in FINETEC  Instruments company. Using this instrument for FINESORB-3010 can carry on program temperature chemical characterization on the condition of non-aided instruments and determine on metal chromatic dispersion, relative activity, absorption strength, acidity neutrality etc. TCD detector inside analyzes the volume of absorption cubage and connects gas phase chromatogram to mass spectrograph. At the same time FINESORB 3010 connects multiple carrier gas to reaction gas. There are multiple carrier gas and reactive gas and mix with certain gas mixture inside instrument. Temperature change with wide scope and temperature control with high precision ensure measure precision, at one time it enhances choice instrument according to the requirement of users and exerts the most practicability and flexibility.

 

FINESORB 3010 is the chemical absorption instruments through temperature programmed charactering catalyst feature. It can realize lots of flow, mainly including TPD, TPR, TPO, TPSR and Pulse Titration.

 

On the research of heterogeneous catalysis makes it very big difficulty in explaining catalytic activity and mechanism, it baffles the best choice for catalyst in the special chemical process because of the complexity of the component and structure of catalyst in itself, relative reaction dynamics system.

 

As one of effective means, chemical absorption supported by temperature programmed technology applies to the research of diversified catalyst widely. The way for temperature programmed chemical absorption is one of typical and effective methods for characterizing catalyst.

Under the diverse temperature with the amount of gas absorption determines activity central quantity, types and fusibility on the surface of catalyst. After degasification, reduction and other surface treatment of the sample, analyzes gas and the activated composition reaction for sample, temperature programmed desorption on the condition of carrier gas.

Under the certain temperature, heat energy will get over activity energy and make the breaking for bond between absorbate and sorbent, then absorption substance will be desorbed. If there are the diversity activity metal, absorption substance usually will be desorbed under the diverse temperature. Desorption molecules enter into inertia gas flow and their concentration will be measured by thermal conductivity cell. From TPD graph can obtain related inform such as desorption peak, desorption temperature point.

 

TPR can determine the amount of catalyst reduction composition and show the temperature when occur to reduction. TPR usually requires catalyst is one of Oxide, namely including metal element can be deoxygenated. When the temperature for sample that is analyzed by mixture gas which mix up reaction gas and carrier gas is variational in linearity, reaction gas will be consumed and make the change of mixture gas composition. At the same time from this way can get the amount of hydrogen consumption through calculating the area of peak which is showed on the graph of TPR.

 

    TPO is one of methods that test the extent for catalyst being oxided. Usually on condition that catalyst is the base metal or the base metal which is transacted by reduction pretreatment, 2 percent of reaction gas which is mixed oxygen with carrier gas transits the sample with the methods of pulse inject sampling or stable air current. When the temperature programmed rises, oxidation will be reacted in certain temperature, then consume oxygen and make the proportion change for the gas of mixture. It measures the consumption of oxygen by detectors.

 

Pulse titration determines activity surface area and crystalloid average granularity of sample through measuring the pulse of reactive gas which transited sample. The chemical reaction for gas and activity composition reacts by many times till all the reaction is finished. Once activity reaction finish, the volume of input and output gas into sample tube is not changed. It forms the same pulse peak on the graph and can calculate surface and average granularity through the area of peak on the graph.

 

 

Multi-working process — TPD, TPR, TPO, TPSR, pulse titration, pretreatment

Multiple independence gas source – except for carrier gas and reaction gas, multiple independent control, mixture in accordance with certain proportion.

Multiple gas interface – 3 for carrier gas, 3 for reaction gas.

Steam generator ---equip with one saturated steam generator, in convenience to use reactive gas, ie: liquid NH₃

Connect GC or MS--- with external joint can joint gas phase chromatogram ( GC ) or mass spectrograph ( MS)

Aided detector – instrument that output one voltage sign connect gas of aided detector, such as FID.

Structure of materials ----  stainless steel pipeline, fluorin rubber for airproof, need to special customization for special application environment.

 

Flux control --- to use software of mass flux controller for controlling, flux can be adjust in 10-100 sccm, software controls gas modulus.

High temperature furnace --- the highest temperature is 1000℃,the speed rate of temperature for furnace from 1℃/min-30℃/min can be adjusted.

Air refrigeration—temperature for open-wide furnace ( shell model ) can be lower rapidly, can choose refrigerating machine to refrigerate rapidly.

Equip with low temperature --- the scope of temperature from -100 begin to rise.

Temperature control –temperature for pipeline, steam generator, furnace, TCD can be controlled by number.

Thermal conductivity cell ---  four arms rhenium tungsten filament TCD, high linearity, high accuracy, high sensitivity and high stability.

Smallest dead cubage --- valve with small cubage and pipe with 3mm lessen the dead cubage so lessen the deviation of peak.

 

Sample bracket --- big size U pipe can be convenient to carrier and wash for sample including powder, stick and pill shape.

Sample carrier --- sample tube that is taken freely can carry sample convenient.

 

Heated pipeline – all the pipeline, valve and liquid steam instruments is heated in order to prevent from condensation.

Security --- over-temperature of furnace is independent protected, decompression valve with air-proof, detected valve, electronic current circuit breaker, fuse, system design for ineffective secure protect.
