Upgrade of Flash Pyrolysis Condensate by Esterification with Higher Alcohols

摘要

1. Esterification, Acetalisation (pure/blank test → upgraded) 1.1 Heating Value: 17/27 MJ kg~(-1) → 31 MJ kg~(-1) 1.2 Water content: 25/12 % → 1 % 1.3 Acid number: 114/49 mg g~(-1) → 20 mg g~(-1) 1.4 Some reactions only feasible in N_2-atmosphere 2. Higher alcohol synthesis 2.1 possible from ethanol 3. Complementary work done at Thuenen-lnstitute for Wood Research (Dr. Meier) 3.1 hydrotreatment of pyrolysis condensate 3.2 hydrotreatment of esterified pyrolysis condensates 3.3 catalyst screening and product quality.
