  • Patent number: 10760004
    Abstract: This disclosure describes systems and methods for using pyrolysis tail gas as the source for additional hydrogen to be used in the pyrolysis reaction. Tail gas is separated from the pyrolysis products and a portion of the tail gas is converted into formic acid (HCOOH). The formic acid is then injected into the pyrolysis reactor where it becomes the donor of two monohydrogen atoms and is ultimately converted into CO2 under reaction conditions. In this fashion, a closed loop pyrolysis hydrogen donor system may be created utilizing a generally non-toxic intermediary derived from the pyrolysis reaction products. This disclosure also describes using a ruthenium catalyst supported on particles of activated carbon to improve the yield of pyrolysis reactions.

  • Patent number: 10688407
    Abstract: Process and apparatus ensure high on-stream reliability of a complex that requires a heat pump which is using a compound having a high boiling point, such as xylenes. When the compressor is shutdown, it can be isolated from the distillation column and receiver while the column is allowed to continue to operate with an auxiliary reboiler for constant heat input. The heat pump can be started up and heated to the normal process temperature, so that when the heavy vapor is charged to the heat pump, it does not immediately condense into liquid, causing damage to the compressor.
