Abstract: A process for the production of glycolaldehyde by thermolytic fragmentation of a carbohydrate feedstock including mono- and/or di-saccharide(s) and a system suitable for performing the process. The process and the system are suitable for industrial application, and the process may be performed in a continuous process. The salt-depleted carbohydrate feedstock may include one or more impurities selected from the group of arsenic, lead, sulfate, sulfur dioxide, and 5-(hydroxymethyl)furfural.

Abstract: A process for the preparation of ethylene glycol and other C1-C3 hydroxy compounds comprising the steps of hydrogenating a composition comprising C1-C3 oxygenate compounds. In particular the process is suitable for hydrogenating a composition comprising different C1-C3 oxygenate compounds, such as the product from a thermolytic fragmentation of a sugar composition.
