  • Methods of co-processing petroleum distillates and bio-based material through a reaction series
    Patent number: 11377603
    Abstract: Methods of processing bio-based material feed (“bio-feed”) and a petroleum feed, using combinations of hydrotreating beds, dewaxing beds, post-treatment beds, and liquid quenching zones. Some methods comprise processing the petroleum feed through first hydrotreating reactor beds; then processing the output with a bio-feed together through second hydrotreating reactor beds; then processing the output through the plurality of dewaxing beds to create a dewaxed stream; and, processing the dewaxed stream through the plurality of post-treatment beds to create a product stream.
