Abstract: The present invention relates to a process for thermolytic fragmentation of a sugar into a composition comprising C1-C3 oxygenates. In particular, it relates to the use of heat carrying particles providing improved yields of C1-C3 oxygenates and improved fluidization characteristics making it suitable for industrial scale production of e.g. glycolaldehyde. It also regards a circulating fluidized bed system comprising the heat carrying particles.

Abstract: The following invention regards a process of demethylating a methyl ester of methionine or its hydroxy analog and producing methane thiol as a side-product. The methionine and its hydroxy analog are suitable as an animal feed additive and as a food additive. The methane thiol may be consumed in a hydrothiolation step such as in a step of preparing the methyl ester of methionine or its hydroxy analog from from methyl vinyl glycolate.
