Abstract:
A process for large scale and energy efficient product on 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.

Claim (Index 1):
A process for thermolytic fragmentation of a sugar into C 1 -C 3  oxygenates, said process comprising the steps of:\n a. providing particles carrying heat and suitable for fluidization; b. providing a fluidized bed fragmentation reactor comprising a riser and suitable for conducting thermolytic fragmentation and suitable for fluidizing a stream of particles; c. providing a feedstock solution comprising a sugar; d. introducing the particles into the reactor at a rate sufficient to maintain a temperature of at least 250\u00b0 C., such as at least 300 350, 400 or 450\u00b0 C., after the thermolytic fragmentation has taken place, and sufficient to obtain a fluidized stream of particles; e. introducing the feedstock into the fluidized stream of particles to obtain thermolytic fragmentation of the sugar to produce a particle dense fragmentation product; then f. separating a fraction of the particles from the particle dense fragmentation product to produce a particle lean fragmentation product; g. quenching the particle lean fragmentation product at least 50\u00b0 C. such that from introducing the feedstock into the particle containing fluidization stream to the quench is performed, the mean residence time of the gas is maximum 5, such as maximum 3 seconds, such as maximum 2, 1, 0.8 or 0.6 seconds; h. recovering the crude fragmentation product, i. transferring the particles separated in step f) to a reheater for heating; and j. recirculating the heated particles to the fragmentation reactor.
