- •
A two-step process for biomass–olefins production via synthetic methanol was simulated.
- •
The mass yield of the system was 0.248 kg light olefins kg−1 biomass.
- •
The system energetic and exergetic efficiencies were 54.66% and 47.65%, respectively.
- •
Biomass gasification, steam cycle and components separation units produced the major irreversibilities.
- •
Main efforts should be made on improvement of biomass gasification and energy integration processes.
