Starch-Based Ultramicroporous Carbon Adsorbents with Ultra-high Methane Uptake

A research dataset from South China University of Technology introduces a method for synthesizing starch-based ultramicroporous carbons. The resulting materials exhibit a methane uptake of 1.86 mmol/g at 100 kPa and 298 K, described as the highest value to date, and a CH4/N2 selectivity up to 5.7. The dataset likely contains experimental results and characterization data supporting the development of carbon-rich materials for gas adsorption.

Use Cases

• Benchmarking methane adsorption performance based on reported uptake values.
• Modeling gas selectivity for separation processes based on CH4/N2 selectivity data.
• Designing porous carbon materials based on insights into pore-size distribution.
• Studying the effects of ionic activation on carbon precursor properties.

Strengths

• Reports a specific, high methane uptake value of 1.86 mmol/g at standard conditions.
• Describes a clear material synthesis method using starch and acrylic acid.
• Quantifies a key performance metric with CH4/N2 selectivity up to 5.7.

Limitations

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