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

Bed material for thermolytic fragmentation of sugars

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.

Production of glycolaldehyde by thermolytic fragmentation

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 including a fluidized stream of heat carrying particles which are separated from the reaction product and directed to a reheater comprising a resistance heating system.

A process for the preparation of ethylene glycol and other C-Chydroxy compounds comprising the steps of hydrogenating a composition comprising C-Coxygenate compounds. In particular the process is suitable for hydrogenating a composition comprising different C-Coxygenate compounds, such as the product from a thermolytic fragmentation of a sugar composition.

A process for large scale and energy efficient product 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. The heat carrying particles may be separated from the fluidized stream prior to cooling the fragmentation product and may be directed to a reheater to reheat the particles and recirculate the heated particles to the fragmentation reactor.

Thermolytic fragmentation of sugars

A method for burning raw materials by which method the raw material and a secondary fuel are separately introduced to one and the same rotary kiln in which the raw material as well as the secondary fuel are heated by gases formed by burning of a primary fuel in the rotary kiln so that the secondary fuel is converted to gases and solid matter in the form of combustion residues such as ashes and coke. The secondary fuel during the process of conversion to gases and solid matter is kept separate from the introduced raw material, which may ensure that the secondary fuel and hence the locally reducing zones and major areas with reducing conditions are brought into minimum contact with the raw material.

Rotary kilns for alternative fuels

A roller mill for grinding particulate material, such as cement raw materials, cement clinker and similar materials has a rotatable grinding table with a substantially vertical centerline and a number of rollers being configured for interactive operation with the grinding table and turning about separate roller shafts which are fixed to a rotatable center shaft with a substantially vertical centerline. The center shaft and the grinding table are fixed one to the rotor and the other to the stator of the same motor, which may have the capability of rotating both the grinding table and the center shaft.
