To give an overview of our catalyst R&D facilities, the following resources and equipment are available to support our product development. Please click on the item title to read more about how it is used.
Catalyst test rigs
In house designed and built test rigs can be used to test a wide range of heterogeneous catalyst reactions including DRI reforming, steam reforming and contaminant removal. A high degree of flexibility allows for a choice of gaseous or liquid feeds at a range of temperatures and pressures with reactions being monitored in real time by use of temperature logging and gas analysis on feed and output using Gas Chromatography.
Micromeritics AutoChem 2920
An automated catalyst characterisation system that can use Temperature Programmed Reduction (TPR), Temperature Programmed Oxidation (TPO) and Temperature Programmed Desorption (TPD) to provide information about catalytic activity, reactive species and interactions between catalytic material and other material present, such as the support. The equipment can also perform Pulse Chemisorption, which can give detailed data about the active surface area, metal dispersion, and average active particle size.
Bulk and side crush strength testers
Crush strength testers for a range of particle sizes, from small granules to large pieces with up to 1000kg crushing force. A bulk crush tester can test on a bed of material at once, to give the % fines produced when subjected to crushing forces such as bed packing.
Heat transfer test rigs
A bed of material is placed within the rig, which is externally heated. A detailed array of thermocouple placed throughout the bed measures the heat as it travels through the material towards the centre, giving useful information about the thermal conductivity of the material taking into account packing, particle to particle contact and gas flow.
Pressure drop, gas flow and packing modelling software
A powerful suite of modelling software can be used to get data on projected pressure drop, gas flow – including thermal data – and particle packing based on shape, size, density and material of each particle.
3D printing and lab-based pilot manufacturing equipment
A stereolithographic 3D printer can be used to quickly make physical representations of prototype designs and concepts which can be combined with a full range of laboratory sized, traditional manufacturing equipment to accelerate product development and testing and allow a large number of prototypes to be made, tested and compared quickly.
Surface Area Analyser – Quantachrome Nova 4200e
Using the principle of nitrogen adsorption and the Brunauer-Emmett-Teller (BET) method, the surface area of solid materials can be determined.
Atomic Absorption Spectrometer – Unicam Solaar AAS
The principle of this method operates on the basis that a vapourised solution of the material to be tested passes through a light. The light absorbed by the vapour can be used to determine the amount of the substance present.
X-ray Fluorescence – Bruker S2 Ranger
This uses EDXRF – energy dispersive X-ray fluorescence spectrometry – so that samples can determined for elemental concentrations from ppm levels upwards. Elements heavier than sodium (atomic number 11) can be analysed.
X-ray Diffraction – Bruker D2 Phaser
Crystalline materials contain a long range order in their structure. Because the electrons in an atom scatter light and the wavelength of X-ray light is similar to distance between atoms in a crystal lattice, the diffraction pattern of X-rays can be used as a “fingerprint” to determine the substance and phases of these substance in a material.
Leco SC632 Sulphur/Carbon analyser
Analyses powdered solid samples for both sulphur and carbon content.
Sir Galahad mercury analyser
The Sir Galahad is capable of determining concentrations of mercury vapour down to nano-grams per cubic meter level in virtually any gas phase.
Merlin mercury analyser
The Merlin mercury analyser measures the concentration of mercury in both solids and liquid samples. The measurement level can be as low as 1 ppb.
PoreMaster pore size analyser
The Quantachrome PoreMaster 33 porosimeter achieves a maximum pressure of 33,000 psia for pore size measurements in the range from over 950 micron to 0.0064 micron pore diameter. It determines, amongst other properties, pore volume, pore size distribution, and calculated surface area of any porous samples.
SRI Gas Chromatograph
This unit has an FID/FPD detector installed. The FID (Flame Ionisation Detector) is able to respond to any molecule with a carbon-hydrogen bond, for example, methane, ethane, and butane. It has a detection range of 0.1ppm to almost 100%. The FPD (Flame Photometric Detector) is able to respond to sulphur species such as hydrogen sulphide and carbonyl sulphide. It can detect down to 200ppb.
Mastersizer 3000 with Hydro EV
This is a laser diffraction particle size analyser. It measures particle size distributions for both wet and dry dispersions over the nanometer to millimeter particle size ranges.
