Biomass feedstock is a renewable source of carbon which is emerged as a focus of interest for becoming an appropriate alternative of fossil fuels. The produced synthesis gas (syngas) from gasification of biomass can be converted to a wide range of liquid hydrocarbons with Fischer-Tropsch (FT) technology. Hybrid process of natural gas and biomass to liquid (GBtL) with capacity of 2000 bbl/day is simulated. The simulation results show that the hybrid process of natural gas and biomass to liquid (GBtL) system can enhance the carbon conversion of the standalone BtL system plant up to 10%. The mass ratio between natural gas and biomass feeds to the process is about 4.5. This is to control the syngas quality to the FT reactor. The techno-economic calculations revealed that the proposed integrated system has enough heating energy suppliers, but the electricity demand is +13 MW for the plant products capacity of about 2000 bbl/day liquid hydrocarbons. The annual profit for this plant is around 4 M$.
