Zero Emissions with Fossil Fuels
Energy Recovery Cycle for Hydrocarbons Without Greenhouse Gas Emissions
This innovative concept proposes the sustainable use of fossil fuels by eliminating greenhouse gas (GHG) emissions through the transformation of hydrocarbons into clean energy sources. The approach combines advanced hydrocarbon processing technologies with fuel cells, creating an integrated and efficient cycle.
Steps of the Energy Recovery Cycle:
- Fossil Fuel Input
- Materials: gasoline, diesel, kerosene, or natural gas, sourced from the existing fossil fuel infrastructure.
- Objective: utilize the energy stored in hydrocarbons while reducing the reliance on direct combustion and its associated emissions.
- Hydrogen Extraction
- Key Processes:
- Steam Reforming: Heating the fuel in the presence of water vapor and metallic catalysts, generating hydrogen (H₂) and byproducts like carbon monoxide (CO). The CO is recycled or captured to avoid emissions.
- Pyrolysis: Thermal decomposition at high temperatures without oxygen, separating hydrogen and producing solid residues like heavy oils or carbon materials.
- Autothermal Reforming: Combines partial oxidation and steam reforming, optimizing the energy efficiency of the process.
- Byproducts: Residues such as heavy oils and plastic polymers are collected for industrial reuse (e.g., manufacturing plastics or asphalt).
- Key Processes:
- Fuel Cell Power Generation
- The extracted hydrogen is used to power fuel cells, which convert hydrogen into electricity efficiently and without GHG emissions.
- Result: The generated energy powers the vehicle and auxiliary systems.
- Energy Recovery for the Process
- Part of the energy generated by the fuel cell is redirected to sustain the hydrogen extraction and purification processes, creating a self-sustaining energy cycle.
