Gas phase maleic anhydride hydrogenation: BASFRecent Research Landscape

Traditional petrochemical feedstocks suffer from price volatility and high carbon footprints, which are mitigated by engineering specific catalytic pathways for renewably-sourced alcohols. This control over the chemical transition from bio-ethanol to higher-order alcohols and polymers ensures supply chain resilience and product sustainability.

What technical problems is BASF addressing in Gas phase maleic anhydride hydrogenation?

Low purity isobutene recovery

(19)evidences

Presence of residual byproducts and low-purity intermediates in the synthesis stream. Achieving high-purity chemical outputs enables downstream polymer grade compliance.

Low product yield instability

(16)evidences

Suboptimal conversion rates and byproduct formation in multi-phase organic syntheses. Improving these metrics prevents feedstock waste and reduces downstream separation costs.

Low aromatic feedstock availability

(13)evidences

Standard alcohol conversion processes often suffer from poor selectivity toward short-chain olefins and high byproduct formation. Improving yield and selectivity enables more efficient production of bio-based chemical precursors.

Low carboxylic acid yield

(6)evidences

Thermodynamic instability or incorrect spatial arrangement of unsaturated carboxylic acid double bonds. Achieving the preferred isomeric form ensures specific chemical properties and downstream processing compatibility.
