  • Patent number: 11517868
    Abstract: A submerged propylene hydration micro-interface strengthening reaction system and a method are proposed. The system includes a reactor, a first micro-interface generator and a second micro-interface generator. Through the micro-interface generators, the propylene is broken to form micron-scale bubbles, which are mixed with reactants and deionized water to form a gas-liquid emulsion, so as to increase a phase boundary area between gas and liquid phases, and achieve a strengthening mass transfer effect under a lower preset operating condition. The micro-scale bubbles can be fully mixed with the deionized water to from a gas-liquid emulsion. By fully mixing gas and liquid phases, it can ensure that the deionized water in the system is in full contact with propylene, and they are fully in contact with the catalyst, which effectively improves the efficiency of preparing isopropanol.

  • Publication number: 20220346089
    Abstract: A wireless access node serves wireless User Equipment (UEs) and wireless Integrated Access and Backhaul Mobile Terminations (IAB MTs). A radio exchanges access communications with the UEs over a frequency channel. The radio receives an IAB request from one of the IAB MTs, and in response, a controller allocates the frequency channel into a UE subchannel and an MT subchannel. The radio now exchanges access communications with the UEs over the UE subchannel and exchanges backhaul communications with the wireless IAB MT over the MT subchannel. The controller reallocates the frequency channel when an IAB MT is added to give the new IAB MT its own MT subchannel. The controller reallocates the frequency channel when an IAB MT is removed to increase the size of the UE subchannel.
