| 20100314235 | HIGH TEMPERATURE HYDROPYROLYSIS OF CARBONACEOUS MATERIALS - Heat from a concentrated solar power source is applied to the conversion of carbonaceous materials such as heavy petroleum crude oils, coals and biomass to liquid hydrocarbons. The solar heat is applied to provide at least a portion of the process heat used in the high temperature, short contact time hydropyrolysis of the carbonaceous material which is supplied with hydrogen generated by a high temperature process such as high temperature steam electrolysis, the sulfur-iodine cycle, the hybrid sulfur cycle, the zinc-zinc oxide cycle or by methane steam cracking. The heat from the solar source may be used to generate electricity to operate high temperature steam electrolysis used in generation of the hydrogen. By the use of solar thermal energy sources, hydrocarbon resource utilization for process heat is eliminated along with carbon dioxide evolution associated with burning of the hydrocarbon resource to generate process heat. The substitution of zero carbon emission sources therefore offers the potential for significant carbon emission reductions in refinery operations where external process heat can be applied and effectively utilized. | 12-16-2010 |
