Catalyst testing is a required first step in devising an effective catalyst management strategy. Pilot testing and audits of catalyst activity though laboratory analysis of catalyst samples can provide insight into methods for extending catalyst life.
Our in-house laboratories perform catalyst testing and analysis to determine catalyst deactivation rates and provide corrective measures for system optimization.
How CORMETECH Measures Catalytic Activity And Potential
|Catalyst Activity Test||Determine the catalyst activity under specific plant or standard conditions through the use of representative-size catalyst samples. Metrics include the catalyst SO2/SO3 conversion rate, pressure drop, initial activity (K0) and actual activity (K).|
|Physical Properties Test||Evaluate physical properties of the catalyst such as its surface area (BET - Brunauer-Emmett-Teller Test) and porosity (or pore volume).|
|Chemical Composition Test||Chemical Composition Test: Evaluate the impact of coal and ash properties on the catalyst and its performance by measuring the catalyst’s chemical composition using quantitative and Semi-quantitative X-Ray Fluorescence (XRF) spectroscopy analysis:
Our testing program includes collection and compilation of field performance data, such as NOx levels, removal efficiency, ammonia-in-ash levels, operational data, and the like. CORMETECH also takes samples of catalyst removed from the field and tests them in its laboratory to assess the catalytic potential against initial design requirements. These tests are done at either standard conditions (single-layer; MR=1), or at actual field conditions (multi-layer; field MR), and often at both conditions to ensure accurate evaluation of the test results. These tests, along with available fuel impact tests (FIELD GUIDE™), provide users current data to assess SCR catalyst system performance. This approach gives users added operational flexibility by analyzing a wide range of catalyst management "what-if" scenarios.
CORMETECH's testing equipment is state-of-the-art and methods are fully conforming to the SCR industry's best practices and VGB guidelines.
