DIRECT COAL LIQUEFACTION LIQUID YIELD IMPROVEMENT BY USING LIGHT LCO DISTILLED FRACTION

Popis výsledku v původním jazyce

Direct coal liquefaction (DCL) has been historically as a standalone process for producing fuels. Nowadays, DCL co-processing with other feeds could be an opportunity for having a cost-effective process. The aim of this work is to obtain high liquids yield by using LCO fraction distilled up to 250 °C (l-LCO) which could be a suitable candidate with similar properties to tetralin. Experiments were carried out in autoclave in nitrogen using brown coal (BC) or in hydrogen using molybdenum supported on BC. Tests were performed at 420 °C with l-LCO/BC ratio of 50/20 g/g or 20/50 g/g. Products were analysed by solubility in heptane, simulated distillation and GCFID/TCD. Main gaseous products were CO2 and methane. Test in nitrogen using 20/50 g/g (l-LCO/BC) resulted in a high amount of liquids (44.3 wt%) and test (PN2 = 20 bar) using 50/20 g/g (l-LCO/BC) led to the increase up to 82 wt% of liquid product.
