Syngas-to-Chemicals Pathway Portfolio Dataset: Product Classification, Conversion Depth En

Barahmand and Eikeland (2025) provide a dataset covering 2,756 classified chemical products across 11 industrial syngas conversion routes. The dataset includes a full classification pipeline using the Enhanced Value Pyramid of Bio-Products taxonomy and computes two composite indices, the EcoStrategic Index and Path-Aware Efficiency index, under four weighting scenarios. Supplementary interactive tools and reference files are included as standalone HTML files.

Use Cases

• Classifying chemical products by value level based on the Enhanced Value Pyramid of Bio-Products taxonomy.
• Assessing portfolio breadth and value composition of conversion routes using the EcoStrategic Index.
• Evaluating conversion depth and step efficiency of pathways using the Path-Aware Efficiency index.
• Comparing strategic rankings of routes through convergence analysis including Spearman rank correlation.
• Reviewing the classification process using provided confidence scores, review flags, and curation logs.

Strengths

• Covers 2,756 classified chemical products across 11 distinct industrial routes.
• Includes a full classification pipeline from raw extraction to curated output, with expert curation of LLM-assisted labels.
• Provides two composite indices (ESI and PAE) calculated under four different weighting scenarios.
• Offers supplementary interactive tools and reference files, including a Python script and a syngas conditioning table.

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.
