摘要： A feed gas stream is introduced directly into a recirculating liquid stream so as to facilitate formation and maintenance of gas bubbles in a dispersed form in a recirculating gas bubble-liquid mixture. By the maintaining of a gas-liquid interface and overhead gas phase in conjunction with a quiescent zone of liquid apart from the portion of liquid in which said mixture is maintained in a recirculating flow condition, the loss of appreciable amounts of gas to the overhead gas phase is avoided.

摘要： A gas mixture preheated to high temperatures using an oxy-fuel, an oxygen-enriched air-fuel or an air-fuel burner is used to devolatilize and partially oxidize carbonaceous feedstock, thereby producing an active residual char that can be used in applications utilizing activated carbon. Use of hot gas and ground carbonaceous feedstock allows the equipment to be minimized, thereby allowing the activated carbon to be produced at or near points of use, for example the production of activated char at or near utility boilers for use in the reduction of mercury emissions from flue gas streams.

摘要： A gas-liquid mixing vessel utilizes an axial flow, down-pumping impeller in a draft tube to create vortex development so as to draw gas from the overhead in a body of recirculating liquid. A surge tank is used to accommodate volume changes in the vessel, and a liquid level control feature, in which the gas phase pressures in the mixing vessel and the surge tank are adjusted, is used to maintain the liquid level in the mixing vessel at a desired level for proper vortex development.
