It has previously been shown that fast pyrolysis can be used to convert glucose to glycolaldehyde in high yields (>50 wt%) along with other chemicals by spraying an aqueous solution of glucose into a fluidized bed operated at 500 – 600 °C [1]. This method of sugar conversion is called “sugar cracking”.
Glycolaldehyde can be hydrogenated in a second step to produce monoethylene glycol (MEG) [2], which is a large commodity chemical with an annual production capacity of 34.8 million tons (2016). MEG is primarily used in the synthesis of polyester fibres and PET bottles (> 80%), while other uses include antifreeze [3].
In this work, a kinetic model for sugar cracking is presented along with experiments investigating the effects of operating conditions with the aim to validate the kinetic model.
