LPG, naphtha, gasoline, diesel, aviation kerosene, paraffin, olefins, chemicals, and so on
Thank you, really thanks! The answer was very detailed
What was the heavy part used for? As fuel?
Reply to 4# hjkupc: Wax can be subjected to hydrocracking to produce fuel, or it can be used directly as a chemical raw material
Reply to 5# fossil-zhang: Are the components heavier than wax used as fuel?
Reply to 6# hjkupc: How could you not read the post carefully? I made it clear: wax is subjected to hydrocracking to produce fuel; how could wax possibly be used as fuel directly?
Wax can be used as fuel--------for candles. Gagagagaga

You didn’t understand what I meant: Components heavier than wax are used as fuel? Is wax the heaviest component in coal-to-oil conversion? Is everything else unreacted coal powder?
Reply to 10# hjkupc: Are you referring to direct liquefaction? I am referring to indirect liquefaction; the heavy components resulting from indirect liquefaction are waxes, and the carbon count of these waxes can reach fifty to sixty. The molecular weight of the components resulting from direct liquefaction is much higher. Solid residues such as coal tar, which contain little or no carbon, have relatively limited utility. For components with a higher carbon content, those that are somewhat lighter can be subjected to hydrocracking; however, it is not cost-effective to use hydrogenation for the heavier components. These can instead be used to produce activated carbon or asphalt, among other things. My understanding of direct liquefaction is not deep enough, so what I say might be incorrect.
