  • Patent number: 11267768
    Abstract: A process for producing olefins by cracking paraffins in the presence of methane. In the conventional steam cracking processes for olefin production, steam is used as a diluent in the feed mixture to the thermal cracker. In the processes provided herein, methane replaces steam as a diluent in the feed mixture to the thermal cracker. Replacing steam with methane as a diluent has a potential for cost savings in the construction and operation of a thermal cracking plant for olefin production. In addition, it leads to a much simpler cracking process compared to the conventional steam cracking technology as in the state of the art.

  • Patent number: 11199453
    Abstract: A method includes directing a first plurality of probe laser pulses through a sample, dividing each of the first plurality of probe laser pulses to generate a first interferogram, and generating first image data reproducible as a first phase image of the sample. A plurality of pump laser bursts are directed onto the sample to heat the sample. A second plurality of probe laser pulses are directed through the sample at a predetermined time delay. Each of the second plurality of probe laser pulses are divided to generate a second interferogram. Second image data is generated that is reproducible as a second phase image of the sample. A transient phase shift is determined in the second phase image relative to the first phase image. A vibrational spectroscopy property is determined of the sample based on the transient phase shift, thereby allowing an identification of chemical bond information of within the sample.
