  • Patent number: 12297391
    Abstract: A method is disclosed for hydrodeoxygenation of a bio-oil over a catalyst bed in a hydrodeoxygenation reactor, the method including combining a two-phase diluent having a water dew point and a bio-oil at a bio-oil temperature that is from 50° F. less than to 50° F. more than the water dew point. The two-phase diluent includes a liquid phase and a vapor phase, where the liquid phase includes a hydrocarbon and the vapor phase includes hydrogen and water.

  • Patent number: 12049434
    Abstract: Paraffin compositions including mainly even carbon number paraffins, and a method for manufacturing the same, is disclosed herein. In one embodiment, the method involves contacting naturally occurring fatty acid/glycerides with hydrogen in a slurry bubble column reactor containing bimetallic catalysts with equivalent particle diameters from about 10 to about 400 micron. The even carbon number compositions are particularly useful as phase change material.
