UKCCSRC C2-189: GC-MS Data for Rejuvenating Degraded Amine Carbon Capture Solvents

GC-MS characterisation results for products from reductive rejuvenation tests on degraded amine sorbents used in carbon capture. The dataset includes results for one industrial MEA solvent, one solid-supported polyethyleneimine sample, and six model MEA degradation compounds, using catalytic hydrogenation, hydrous pyrolysis, and hydropyrolysis with platinum, nickel, and molybdenum catalysts. Preliminary CO2 absorption test results for a degraded MEA solvent before and after rejuvenation are also included, produced by the British Geological Survey under UKCCSRC Call 2 funding.

Use Cases

• Comparing rejuvenation method efficacy based on GC-MS characterisation results for degraded solvents.
• Analyzing catalyst performance (platinum, nickel, molybdenum) in reductive approaches like catalytic hydrogenation.
• Evaluating CO2 absorption capacity changes before and after hydrous pyrolysis rejuvenation.
• Studying the chemical profiles of specific model degradation compounds like 1-(2-Hydroxyethyl)-2-imidazolidinone.

Strengths

• Data covers multiple reductive rejuvenation methods: catalytic hydrogenation, hydrous pyrolysis, and hydropyrolysis.
• Includes results for eight distinct sample types: one industrial MEA, one solid-supported polyethyleneimine, and six model compounds.
• Contains preliminary performance data linking chemical characterisation to functional CO2 absorption tests.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
