Abstract:
1. A process for the production of hydrocarbon-containing oils, in which process a starting material containing a sugar and/or a sugar derivative is thermally cleaved, comprising: a reaction step in which the starting material is brought into contact with a contact oil which has an initial boiling point of at least about 200° C. at a pressure of about 1013 mbar with formation of a reaction phase at a reaction temperature in the range of from about 200 to about 600° C. and a pressure in a range of from about 0.1 to about 25 bar; and a processing step in which the reaction phase is separated into a low-boiling fraction and a high-boiling fraction, wherein at least a portion of the high-boiling fraction is recirculated into the reaction step as contact oil.
