How Raj Process 2G Ethanol Plants Work

1. Biomass Pretreatment

• Mechanical, chemical, or steam-based pretreatment
• Breaks down hemicellulose and lignin to enhance enzyme accessibility
• Optimized for bagasse, rice straw, bamboo, corn stover

2. Enzymatic Hydrolysis

• Specialized cellulase and hemicellulase enzymes
• Converts cellulose and hemicellulose into fermentable C6 and C5 sugars
• Maximizes sugar recovery with minimal inhibitors

3. Fermentation

• Engineered yeast and microbial strains
• Co-fermentation for glucose (C6) and xylose (C5)
• Efficient ethanol conversion

4. Distillation & Dehydration

• Multi-pressure vacuum distillation for fuel-grade ethanol
• Molecular sieve dehydration → 99.5% purity

5. Co-Product Recovery & Integration

• Lignin recovery → bio-CNG, power generation, pellets
• Carbon dioxide capture for industrial use
• Integration with CBG plants and ZLD systems

Applications of 2G Ethanol

• Ethanol Blending Program → Supporting India’s 20% target by 2030
• Biofuel Substitution → Replacing fossil gasoline
• Industrial Use → Pharmaceutical, beverage, specialty chemicals
• Integrated Energy Systems → Lignin utilization for power and steam

Benefits of 2G Ethanol Plants

• High Conversion Efficiency → Up to 85% cellulose-to-ethanol yield
• Energy Optimization → Heat integration and recovery
• Future-Ready → Integration with CBG plants, SAF, green hydrogen
• Regulatory Compliance → SATAT, BIS, MoPNG norms
