Abstract
The present invention relates to a method for thermolytic fragmentation of a sugar into C1-C3 oxygenates, comprising separating solids from the fragmentation product, wherein the temperature of the fragmentation product at an outlet of the reactor is at least 250° C., and wherein the water content is at least 40 vol. %, based on all gas phase constituents. The present invention also relates to a system for performing the thermolytic fragmentation of a sugar into C1-C3 oxygenates. The method and the system are suitable for industrial scale production.
Claims18
A process for thermolytic fragmentation of a sugar into C1-C3 oxygenates, the process comprising the steps of:
- a) providing an aqueous feedstock solution comprising the sugar;
- b) providing a fluidised bed fragmentation reactor for thermolytically fragmenting the sugar and comprising fluidisable heat carrying particles;
- c) introducing the feedstock solution into the reactor to thermolytically fragment the sugar to provide a fragmentation product comprising the C1-C3 oxygenates;
- and
- d) separating solids from the fragmentation product, wherein the solids comprise solids selected from the fluidisable heat carrying particles, fragments of the fluidisable heat carrying particles, by-products from the thermolytic fragmentation of the feedstock solution, and mixtures thereof;
- wherein the temperature of the fragmentation product at an outlet of the reactor is at least 250° C., and
- wherein the water content is at least 40 vol. %, based on all gas phase constituents.
A system for thermolytic fragmentation of a sugar into C1-C3 oxygenates, the system comprising:
- a) an aqueous feedstock solution comprising the sugar;
- b) a fluidised bed fragmentation reactor configured to thermolytically fragment the sugar and comprising fluidisable heat carrying particles thereby to provide a fragmentation product comprising the C1-C3 oxygenates;
- and
- c) a separation device configured to separate solids from the fragmentation product, wherein the solids comprise solids selected from the fluidisable heat carrying particles, fragments of the fluidisable heat carrying particles, by-products from the thermolytic fragmentation of the feedstock solution, and mixtures thereof;
- wherein the temperature of the fragmentation product at an outlet of the reactor is at least 250° C., and wherein the water content is at least 40 vol. %, based on all gas phase constituents.
