    摘要： In at least one embodiment of the present invention, a method of recovering energy from a FCC unit having a reactor and a regenerator for overall CO 2 reduction is provided. The method comprises cooling syngas to a predetermined low temperature to define cooled syngas. A turbo-expander including a first compressor is provided. The turbo-expander train is configured to combust and expand gas to drive the first compressor. The cooled syngas is compressed with the first compressor to define compressed syngas. A first stream of gas comprising CO 2 and a second stream of gas comprising CO are separated from the compressed syngas. O 2 and the first and second streams of gas are introduced to the turbo-expander train. The first stream of gas is expanded and the second stream of gas is combusted and expanded with the O 2 to recover energy, driving the first compressor and producing the syngas.

    摘要： The invention provides compositions and methods to reduce NOx emissions from the flue gas of a fluid catalytic cracking (FCC) unit (10). The invention also provides methods for reducing CO emissions from the regenerator (2) and/or the flue of an FCC unit. The compositions (4) of the invention comprise copper and/or cobalt and a carrier. The carrier can be, for example, hydrotalcite like compounds, spinels, alumina, zinc titanate, zinc aluminate, zinc titanate/zinc aluminate, and the like.

    摘要： Conversion of carbon monoxide within the regenerator of a cracking unit used to regenerate spent catalysts from the catalytic cracking of gas oil is enhanced by the addition of controlled amounts of copper chromite, cobalt chromite, or mixtures thereof. Conversion of carbon monoxide in the regenerator is accomplished while maintaining the efficiency of the cracking reaction at high levels.
    The amount of chromite oxidation catalyst is maintained below 500 ppm based on total cracking catalyst inventory.
