摘要： The present invention relates to a process for thermolytic fragmentation of a sugar into a composition comprising C 1 -C 3 oxygenates. In particular, it relates to the use of heat carrying particles providing improved yields of C 1 -C 3 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.

摘要： A process for large scale and energy efficient production of oxygenates from sugar is disclosed in which a sugar feedstock is introduced into a thermolytic fragmentation reactor comprising a fluidized stream of heat carrying particles which are separated from the reaction product and directed to a reheater comprising a resistance heating system.
