Techno-economic modelling of coal conversion processes for liquid fuel production
This report describes the modelling of indirect coal liquefaction processes for the purpose of performing a technical and economic assessment of the production of liquid fuels from coal and lignite, using a variety of gasification and synthesis gas liquefaction technologies. The technologies are being modelled on a "step model" basis, where a step is defined as a combination of individual unit operations, which together perform a significant function on the process streams, such as a methanol synthesis step or a gasification and physical gas cleaning step. Sample results of the modelling, covering a wide range of gasifiers, liquid synthesis processes and products, are presented. The main results show that methanol is the cheapest fuel that can be produced from coal, followed by fuel alcohol, diesel from the Shell middle distillate synthesis process, diesel from the Mobil methanol olefins gasoline diesel process, gasoline from the same process and finally gasoline from the Mobil methanol to gasoline process. There is some variation in the production costs of all the products, depending on the type of gasifier chosen and the feedstock.
