Process for converting carbon-based energy carrier material
View Patent ↗A process is disclosed process for converting a solid or highly viscous carbon-based energy carrier material to liquid and gaseous reaction products, said process comprising the steps of: a) contacting the carbon-based energy carrier material with a particulate catalyst material b) converting the carbon-based energy carrier material at a reaction temperature between 200° C. and 450° C., preferably between 250° C. and 350° C., thereby forming reaction products in the vapor phase. In a preferred embodiment the process comprises the additional step of: c) separating the vapor phase reaction products from the particulate catalyst material within 10 seconds after said reaction products are formed. In a further preferred embodiment step c) is followed by: d) quenching the reaction products to a temperature below 200° C.
1. A process for converting a solid or highly viscous carbon-based energy carrier material to liquid and gaseous reaction products, said process comprising the steps of:
a) sensitizing the carbon-based energy carrier material to produce a sensitized material, wherein the carbon-based energy carrier material is a solid biomass;
b) contacting the sensitized material with a particulate catalyst material, wherein the step of contacting is carried out in a fluidized bed;
c) converting the sensitized material at a reaction temperature between 200° C. and 450° C., thereby forming reaction products in the vapor phase, in the presence of a reductive gas and wherein the reductive gas comprises iso-butane, naphthene, a volatile organic acid, or combination thereof;
d) separating at least a portion of the reaction products from the particulate catalyst material within 10 seconds after the reaction products are formed; and
e), optionally quenching the reaction products to a temperature below 200° C.
2. The process of claim 1 wherein said sensitizing in step a) comprises contacting the carbon-based energy carrier material with a portion of the reaction products from step c).
