Catalytic Activity and Selectivity Evaluation in Our Detection Service for Hydrogen Conversion Catalysts

• Fixed-bed catalytic activity test per internal validated protocol and customer specifications — the catalyst is loaded into a laboratory reactor and challenged with a representative feed gas containing hydrogen and the target reactant, and the conversion rate, product yield, and space-time yield are measured under controlled temperature, pressure, and gas hourly space velocity to verify the catalyst's hydrogen conversion activity.
• Selectivity and product distribution analysis by gas chromatography per ASTM D1945 and internal methods — the reactor effluent is analyzed to quantify the target product and any by-products, verifying the catalyst achieves the required selectivity for the desired hydrogen conversion reaction and minimizes undesirable side reactions.
• Turnover frequency and intrinsic activity measurement per internal protocols — the reaction rate per active metal site is calculated from the measured conversion and the metal dispersion, providing a fundamental measure of catalyst performance independent of metal loading.
• Temperature-programmed reduction and temperature-programmed desorption per ASTM D4824 — the reducibility of the metal oxide precursor and the interaction of hydrogen with the catalyst surface are characterized to define the activation procedure and to verify the catalyst's hydrogen adsorption capacity.
• Hydrogen chemisorption and metal dispersion measurement per ASTM D3908 — the amount of hydrogen chemisorbed on the active metal surface is measured to determine the metal dispersion and the active surface area, which directly correlate with catalytic activity per unit mass of catalyst.
• Accelerated deactivation and sulfur poisoning resistance testing per ASTM D6591 — the catalyst is exposed to a feed containing defined sulfur or carbon monoxide concentrations, and the loss of activity over time is measured to predict the tolerance to catalyst poisons in real hydrogen conversion processes.
• Regeneration and reactivation cycle testing per customer protocols — the spent catalyst is subjected to oxidative regeneration or hydrogen reactivation cycles, and the recovered activity is measured to determine the number of useful cycles and the economic life of the catalyst.

Physical and Structural Characterization for Hydrogen Conversion Catalysts

• Specific surface area and pore volume by BET nitrogen adsorption per ISO 9277 and ASTM C1274 — the surface area and porosity of the catalyst support are measured to verify the material provides sufficient active surface for metal dispersion and reactant access in the hydrogen conversion reactor.
• Pore size distribution by Barrett-Joyner-Halenda method per ISO 15901-2 — the mesopore and micropore size distribution is calculated to ensure the catalyst pore architecture allows diffusion of reactants and products without excessive mass transfer limitations.
• Particle size distribution by laser diffraction and sieving per ISO 13320 and ASTM D1921 — the D10, D50, and D90 values are measured to ensure the catalyst particles meet the specified size range for the reactor bed configuration and to predict pressure drop.
• Bulk density and packed bed density per ASTM D2854 and ISO 3953 — the catalyst density is measured for reactor loading calculations and to verify batch-to-batch consistency in the manufacturing process.
• Single pellet crushing strength and bulk crushing resistance per ASTM D4179 and ASTM D6175 — the force required to crush individual catalyst pellets or extrudates is measured to ensure the catalyst withstands bed weight, pressure cycling, and handling without excessive breakage or dust formation.

Thermal Stability and Regeneration Performance Testing for Hydrogen Conversion Catalysts

• Thermogravimetric analysis and differential scanning calorimetry per ASTM E1131 and ISO 11357-1 — the thermal decomposition profile, phase transitions, and any exothermic reactions of the fresh and spent catalyst are recorded to define safe operating and regeneration temperature windows and to prevent thermal runaway during catalyst activation.
