Latest Patents

Diao is associated with 1 patent: “Two-stage co-liquefaction mixing-reaction-filtration-heat recovery integrated apparatus.” The invention supports a two-stage HTL process and uses nozzles, receiving chambers, mixing chambers, and diffusion chambers to bring high-speed fluids into contact and promote mixing.

The apparatus also recovers heat from the second-stage HTL product to supply heat to the first stage, with the aim of improving process efficiency. High-temperature, high-pressure needle valves allow the first-stage reaction time to be adjusted for different feedstock characteristics. The design further specifies first-stage reaction tubes inclined by 1–3 degrees and equips the second-stage generation chamber with residue- and salt-scraping devices.
