Gas-solid cocurrent downflow(downer) reactors offer many advantages over gas-solid cocurrent upflow(riser) reactors, such as better gas-solids contact efficiency, more uniform gas and solids residence time distributions and the potential capability of handling higher solids-gas loading ratios. These features make the downer an excellent reactor for fast reactions and especially for fast reactions where the intermediate is the product. This new type of reactor has so far not been well developed but has huge potential for many industrial processes such as fluid catalytic cracking of crude oil where further improvement in the gas-solids contact efficiency will lead to significant economic gains, pyrolysis of some solids waste into valuable organic products which provides a more energy efficient alternative to waste incineration... 1, record 2, English, - cocurrent%20downflow%20reactor

... other heat-treating processes applied in sludge incineration are the flash drying incineration system and the fluidized bed reactor... A fluidized bed reactor uses a sand bed which is kept in fluid condition by an upflow of air, as a heat reservoir to promote uniform combustion of sludge solids. The bed is preheated to approximately 122 °F by using fuel oil or gas. When sludge cake is introduced, rapid combustion occurs maintaining an operating temperature of about 1500 °F. 1, record 5, English, - fluidized%20bed%20reactor

A representative medium-consistency system is shown in Figure 11-19. Pulp from a brown stock washer or decker at about 10-14% consistency is charged with caustic or oxidized white liquor. It is then preheated in a low-pressure steam mixer and pumped through one or more medium-consistency gas mixers to an upflow pressurized reaction tower. Steam and oxygen are added upstream of the medium-consistency mixer or are added directly into it. The reactor bottom may be hemispherical or conical, and the top is equipped with a discharger.... The stock is depressurized through a separator where steam is flashed and small amounts of by-product gases, oxygen and other noncondensibles are released. 1, record 6, English, - medium%2Dconsistency%20oxygen%20delignification

anaerobic filter system. A technology used in anaerobic digestion suited to liquid effluents with high levels of dissolved organic matter and relatively low levels of particulate solids. In an anaerobic filter, the biomass is retained by trapping or immobilizing on a fixed carrier which may be in the form of large plates, specially designed random plastic supports, or broken pieces of rock or similar material. The reactor may be run as a continuous process in either an upflow or a downflow mode. Retention of the cells on a support gives a high ratio of solids retention time to hydraulic retention time, permitting high rates of throughput. 2, record 7, English, - anaerobic%20filter%20reactor
