Abstract: Improved processes and systems for removing CO2 from exhaust gas to substantially prevent such greenhouse gas from being released to the atmosphere. The systems and processes use a) staged cooling of an exhaust gas stream, b) addition of an antifreeze, and c) a combination of non-scraped heat exchangers and scraped heat exchangers to separate CO2 from an exhaust stream while reducing or minimizing accumulation of ice on surfaces within the system.

Abstract: Apparatuses and methods are provided for generating elemental hydrogen and carbon from a hydrocarbon feed. In some examples, the apparatus can include a first tube and a second tube. The first tube can be configured to carry a hydrocarbon feed along a first flow path. The second tube can be configured to carry a fuel and an oxygen-containing gas along a second flow path, where the first flow path and second flow path are countercurrent. A porous wall can sperate the first tube from the second tube where the porous wall can be configured to allow heat and gas to pass from the second tube to the first tube.
