The SCR filter has a substrate constructed using bonded fiber structures, which cooperate to form a highly uniform open cell network, as well as to provide a uniform arrangement of pores. The substrate typically is provided as a wall-flow honeycomb structure, and in one example, is manufactured using an extrusion process. In this way, the substrate has many channel walls, each having an inlet surface and an outlet surface. The inlet surface has a uniform arrangement of pores that form a soot capture zone, where soot and other particulate matter is captured from an exhaust gas. A NOx conversion catalyst is disposed inside the channel wall, where NOx and ammonia in the exhaust gas are reacted to less harmful substances. Because of the uniform pore structure and open cell arrangement inside the channel wall, the filter is capable of being heavily loaded with catalyst, while avoiding undue increase in backpressure to the internal combustion engine. | 09-30-2010 |

The combination corona discharge reactor is a modularized structure constructed subject to actual requirements, practical for decomposing waste lubricating oil, insulation oil, milling oil and smokes discharged from a kitchen, smoking room, motor vehicle or machine. | 03-17-2016 |

| 20160376230 | UREA GRANULATION PROCESS WITH SCRUBBING SYSTEM - A urea granulation process with a scrubbing system may involve at least one gaseous waste stream for removal of dust and ammonia whereby the waste stream may be processed through a combination of process steps. In some examples, the process steps may involve washing the dust and ammonia laden stream with water and/or an aqueous urea solution whereby a dust-laden liquid stream and a dust-reduced stream is generated. The process steps may further involve reacting the dust-reduced stream with formaldehyde to form a stream comprising hexamethylenetetramine and urea-formaldehyde and clean off-gas. In some cases, the gas stream may be directed first through the washing step and then through the reacting step. | 12-29-2016 |
