Molecular Formula: C₆H₆

CAS Number: 71-43-2

Structural Formula:

Pure benzene is a hydrocarbon obtained through the hydrogenation and extraction of crude benzene.

Shandong Huineng employs low-temperature hydrogenation and extraction processes for production, primarily represented by Axens' low-temperature gas-liquid two-phase hydrogenation technology from the United States and Uhde's low-temperature gas-phase hydrogenation technology from Germany. This process is stable, yielding high-purity benzene that is virtually indistinguishable from petroleum-derived benzene.

Hydrorefined benzene is a new environmentally friendly process.

High-purity hydrogen extracted from coke oven gas via PSA is added to crude benzene in the benzene hydrogenation process. Through hydrogenation, extraction, and distillation, high-purity benzene is obtained, typically with a purity of 99.95%. With process optimization, the company achieves a purity of over 99.99%.
