9.2.4 Mass balance of pyrolysis
Companies A and B provided us with the mass balance
of their full-scale pyrolysis plants when processing their
regular input material (all figures in wt%):
Company A producing gasoline:
• 17% syngas
• 15% light fraction for internal use in the plant
• 62% gasoline fraction
• 5% char
• 1% water

The gasoline fraction is further treated by column distillation
that yields the mass balance:
• 1% light oil fraction
• 86% gasoline fraction suited for diesel engines of road
vehicles
• 7% kerosene suited for power generators
• 7% heavy fraction to be returned to the pyrolysis
process

Company B producing marine fuel:
• 15% syngas
• 77% marine fuel
• 7% char
• 1% water
