摘要：

A comprehensive experimental and modelling study on the acid-catalysed hydrolysis of the water hyacinth plant (Eichhornia crassipes) to optimise the yield of levulinic acid (LA) is reported (T = 150-175 degrees C, C-H2SO4 - 0.1-1 M, water hyacinth intake = 1-5 wt%). At high acid concentrations (> 0.5 M), LA was the major organic acid whereas at low acid concentrations (< 0.1 M) and high initial intakes of water hyacinth, the formation of propionic acid instead of LA was favoured. The highest yield of LA was 53 mol% (35 wt%) based on the amount of C6-sugars in the water hyacinth (T = 175 degrees C, C-H2SO4 = 1 M, water hyacinth intake = 1 wt%). The LA yield as a function of the process conditions was modelled using a kinetic model originally developed for the acid-catalysed hydrolysis of cellulose and good agreement between the experimental and modelled data was obtained.
