Abstract:

Beside thermo­chemical processes like pyrolysis and gasification another process group called hydrothermal conversion comes into the focus of research for the treatment of biomass. Especially for wet biomass this process has several advantages. As the reaction medium is water, wet biomass does not need to be dried. By processing wet biomass continuously several advantages can be achieved which may lead to a higher percentage of liquefied products and also a better selectivity towards specific products. For the proposed work model compounds of biomass (Glucose, Fructose, Cellulose and real biomass) are hydrothermally treated at a great matrix of parameter variations. The different reaction times and temperatures showed good correlation to the formation rate of several substances, e.g. by choosing the right holding time a conversion yield of 5­HMF of 16 wt.% was achieved. The utilization of a model biomass (Baby food) also gave high variations concerning glucose and 5­HMF yield depending on reaction time and temperature. The experiments illustrate the possibility to produce intermediate chemicals from biomass in an economic and feasible way
