Systems, methods, and compositions for production of synthetic hydrocarbon compounds
InactiveUS20060211777A1Efficient processingReduce energy lossElectrolysis componentsLiquid hydrocarbon mixture productionKeroseneHydrocotyle bowlesioides
A process and system for producing hydrocarbon compounds or fuels that recycle products of hydrocarbon compound combustion—carbon dioxide or carbon monoxide, or both, and water. The energy for recycling is electricity derived from preferably not fossil based fuels, like from nuclear fuels or from renewable energy. The process comprises electrolysing water, and then using hydrogen to reduce externally supplied carbon dioxide to carbon monoxide, then using so produced carbon monoxide together with any externally supplied carbon monoxide and hydrogen in Fischer-Tropsch reactors, with upstream upgrading to desired specification fuels—for example, gasoline, jet fuel, kerosene, diesel fuel, and others. Energy released in some of these processes is used by other processes. Using adiabatic temperature changes and isothermal pressure changes for gas processing and separation, large amounts of required energy are internally recycled using electric and heat distribution lines. Phase conversion of working fluid is used in heat distribution lines for increased energy efficiency. The resulting use of electric energy is less than 1.4 times the amount of the high heating value of combustion of so produced hydrocarbon compounds when carbon dioxide is converted to carbon monoxide in the invention, and less than 0.84 when carbon monoxide is the source.

Next, a desired elevated temperature limit is established for heated air that is to be circulated through the application zone. Heaters are provided in airflow communication with the application zone, and circulation fans are positioned throughout the application zone to move the heated air for proper heat distribution. The heaters utilize an amount of recirculated air already present in the application zone to cut down on the amount of energy needed to raise the air temperature within the application zone towards the desired elevated temperature limit, and to eliminate the need for high CFM airflow heaters to achieve air temperature elevation. The temperature at various nodes within the application zone may be monitored to allow personnel to redirect circulating airflow within the application zone to balance out areas of higher air temperature with areas of lower air temperature. The method takes advantage of convection heat transfer to raise the temperature evenly within an application zone, minimizing temperature stratification which could result in ineffective pest extermination and / or damage to equipment and facilities.
