The present disclosure includes various methods systems and apparatuses for carbon dioxide capture and utilization such as for encapsulation in asphalt. For example, a method can include combusting fuel to generate a flow of exhaust from a working machine operating to perform one or more asphalt related tasks, capturing CO2 from the exhaust, storing the CO2 in a storage unit onboard the working machine, forming asphalt that includes an amount of the CO2 from the storage unit by selectively mixing the amount of the CO2 from the storage unit with calcium, and using the asphalt that is formed that includes the amount of the CO2 from the storage unit encapsulated therein at a jobsite.

A carbon dioxide capture system includes a first capture tank containing carbon dioxide absorbent material which operates to absorb carbon dioxide from a flow of exhaust gas from an internal combustion engine. A heat exchange loop is in heat exchange communication with the first capture tank and further in heat exchange communication with one of the flow of exhaust gas or a flow of engine coolant from the internal combustion engine. A heat exchange fluid is operable to flow through the heat exchange loop. The heat exchange fluid operates to transfer heat from the exhaust gas or the engine coolant to the first capture tank. The heat from the exhaust gas or the engine coolant operates to release a portion of the carbon dioxide absorbed by the carbon dioxide absorbent material in the first capture tank.

A gasoline engine exhaust gas purification catalyst for purifying exhaust gas emitted from a gasoline engine includes a precious metal, alumina, and a ceria/zirconia composite oxide supported on a three-dimensional structure, and has pores having a peak 1 at a pore size of not less than 0.001 μm and not greater than 0.05 μm, pores having a peak 2 at a pore size of not less than 2.5 μm and not greater than 5.0 μm, and pores having a peak 3 at a different pore size than the above pore sizes in a pore size distribution measured by mercury intrusion method, wherein the pore volume of the pores having the peak 3 is greater than 1.4% of the total pore volume. A production method for the catalyst, and an exhaust gas purification method using the catalyst are also described.

The present invention relates to an apparatus for reducing greenhouse gas emission in a vessel and a vessel including the same, in which CO.sub.2 absorbed by taking only a part of the absorbent liquid used when collecting CO.sub.2 is removed, so that the device sizes of an absorbent liquid recycling unit and an absorbent liquid circulating unit is kept small and continuous operation is enabled. Or in which exhaust gas is cooled by a heat exchange method, thereby preventing the decrease in a concentration of an absorbent liquid, and CO.sub.2 absorbed by taking only a part of the absorbent liquid used when collecting CO.sub.2 is removed and an unreacted absorbent liquid is continuously circulated, thereby enabling continuous operation.

A method for mobile carbon capture, preferably including adsorbing a target species, desorbing the target species, and storing the target species. The method can optionally include pre-treating input gas, offloading stored species, and/or regenerating desiccators.

The present invention relates to an apparatus for reducing greenhouse gas emission in a vessel and a vessel including the same, which are capable of constantly maintaining a concentration of a greenhouse gas absorbing liquid to prevent a decrease in absorption performance of an absorption tower, and applying a pressurization system to prevent the loss of an absorbent liquid due to the natural evaporation of a high-concentration absorbent liquid. Or which are capable of cooling exhaust gas with fresh water by a heat exchange method, thereby preventing a decrease in concentration of an absorbent liquid, and controlling the concentration of the absorbent liquid to constantly maintain the concentration of the absorbing liquid, thereby preventing a decrease in absorption performance.

A method and modular desulfurization-decarbonization apparatus for removing contaminants from exhaust gas is described. The apparatus comprises discrete modular units with distinct functions. The modular units may be housed in standard shipping containers and installed on cargo ships. The modules can be removed and replaced while docking with minimal disruption to ship and port operations.

A bottoming cycle power system includes a turbine-generator. The turbine-generator includes a turbo-expander and turbo-compressor disposed on a turbo-crankshaft. The turbo-expander is operable to rotate the turbo-crankshaft as a flow of exhaust gas from a combustion process passes through the turbo-expander. The turbo-compressor is operable to compress the flow of exhaust gas after the exhaust gas passes through the turbo-expander. An exhaust gas heat exchanger includes first and second flow paths operable to exchange heat therebetween. The first flow path is operable to receive the flow of exhaust gas from the turbo-expander prior to the exhaust gas being compressed by the turbo-compressor. The second flow path is operable to receive the flow of exhaust gas from the turbo-compressor after the exhaust gas has been compressed by the turbo-compressor.

A control system for a vehicle having a CO2 capturing device configured to capture CO2 certainly from gas streams. The CO2 captured by the CO2 capturing device is desorbed from the CO2 capturing device by an energy available in the vehicle. A controller is configured to discharge the CO2 captured by the CO2 capturing device into the recovery station by energy delivered from the recovery station to the CO2 capturing device when the energy available in the vehicle is less than a predetermined value.
