RESUMO
This detail the economics of Catalytic Hydrothermolysis (CH), an approve pathway for sustainable aviation fuel (SAF) production. Techno-economic analysis was conducted with the assumption of CH processing facility that process 832 metric tonnes per day of feedstock into renewable fuels such as SAF, gasoline and diesel. Economic data includes estimation of renewable fuel production plant cost such as capital and operating cost; cost benefit analysis model to predict the SAF or jet fuel price; regression models to evaluate the cost for co-product such as diesel and petroleum in relation to SAF price. Estimated SAF, gasoline and diesel cost for the feedstock such as carinata oil, soybean oil, yellow grease and brown grease feedstock is included in the data.
RESUMO
The alcohol-to-jet (ATJ) process is a method for the conversion of alcohols to an alternative jet fuel blendstock based on catalytic steps historically utilized by the petroleum refining and petrochemical industry. This pathway provides a means for producing a sustainable alternative jet fuel (SAJF) from a wide variety of resources and offers a near-term opportunity for alcohol producers to enter the SAJF market and for the aviation sector to meet growing SAJF demand. Herein, the technical background is reviewed and selected variations of ATJ processes evaluated. Simulation and modeling were employed to assess some ATJ conversion schemes, with a particular focus on comparisons between the use of an ethanol or isobutanol intermediate. Although the utilization of isobutanol offers a 34 % lower conversion cost for the catalytic upgrading process, the cost of alcohol production is estimated to contribute more than 80 % of the total cost at the refinery. The cost of feedstock and alcohol production has a dominant effect on the overall process economics.
