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 method and a system for producing glycolic acid and/or glycolate from sustainable resources. A method for catalytic production of glycolic acid and/or glycolate including the step of: oxidation of a starting material including between 0.1-100 wt/wt % glycolaldehyde at a temperature of between &#x2212;10&#xb0; C. and 100&#xb0; C. with an oxidant in the presence of a metal-based catalyst including a catalytically active metal, which is selected from the group of palladium and platinum; or mixtures thereof.

Process for the preparation of ethylene glycol from sugars

A method for removing sulphur compounds from a process stream by contacting the process stream with an aqueous solution containing glycolaldehyde as the predominant compound.

Process for removing sulphur compounds from process streams

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 process for the preparation of lactic acid and 2-hydroxy-3-butenoic acid or esters thereof from a sugar in the presence of a metallo-silicate material, a metal ion and a solvent, wherein the metal ion is selected from one or more of the group consisting of potassium ions, sodium ions, lithium ions, rubidium ions and caesium ions.

Process for the conversion of sugars to lactic acid and 2-hydroxy-3-butenoic acid or esters thereof comprising a metallo-silicate material and a metal ion
