A Techno-Economic Assessment of Renewable Diesel and Gasoline Production from Aspen Hardwood

A Techno-Economic Assessment of Renewable Diesel and Gasoline Production from Aspen Hardwood In this study, we developed a techno-economic model to estimate the production cost of renewable diesel and gasoline from aspen woodchips through fast pyrolysis-based bio-oil and its subsequent hydroprocessing. The whole pathway includes the conversion of woodchip biomass to bio-oil through fast pyrolysis followed by upgrading to transportation fuels via hydro- processing. Experiments were carried out to develop for the process model. This detailed process and techno-economic −1 study was done based on 2000 dry t day aspen woodchips (base case capacity), from which we estimated the cost to −1 produce renewable diesel and gasoline. For this base case, using the present method, 148.81 ML year of renewable diesel −1 and 99.21 ML year of gasoline using merchant hydrogen can be produced. The production costs of renewable diesel and −1 −1 gasoline for 2000 t day are 1.09 and 1.04$ L , respectively. We also studied the effect of changing the scale of the facility −1 from 500 to 5000 t day on the production costs of renewable diesel and gasoline. The economic optimum plant size (the −1 capacity at which fuel production cost is lowest) was determined to be 3000 t day .

Abstract

In this study, we developed a techno-economic model to estimate the production cost of renewable diesel and gasoline from aspen woodchips through fast pyrolysis-based bio-oil and its subsequent hydroprocessing. The whole pathway includes the conversion of woodchip biomass to bio-oil through fast pyrolysis followed by upgrading to transportation fuels via hydro- processing. Experiments were carried out to develop for the process model. This detailed process and techno-economic −1 study was done based on 2000 dry t day aspen woodchips (base case capacity), from which we estimated the cost to −1 produce renewable diesel and gasoline. For this base case, using the present method, 148.81 ML year of renewable diesel −1 and 99.21 ML year of gasoline using merchant hydrogen can be produced. The production costs of renewable diesel and −1 −1 gasoline for 2000 t day are 1.09 and 1.04$ L , respectively. We also studied the effect of changing the scale of the facility −1 from 500 to 5000 t day on the production costs of renewable diesel and gasoline. The economic optimum plant size (the −1 capacity at which fuel production cost is lowest) was determined to be 3000 t day . Finally, we carried out sensitivity and uncertainty analyses for the base case and determined that production cost is most
