Patent number: 7638101Abstract: This invention relates to regeneration of coked catalyst by combustion so that the catalyst can be reused in a hydrocarbon conversion reaction. The completion of coke burn is generally measured with a combination of temperature or change in oxygen concentration. Dropping outlet temperatures require time to wait for increases in inlet temperature to correspondingly move down the regenerator. Faster response times might be expected from increasing oxygen concentration, but a small increase in concentration can lead to a significant increase in peak burn temperature which negatively impacts catalyst life. Controlled peak burning is difficult over the entire bed by merely controlling inlet and outlet oxygen concentrations. The invention accordingly combines a measured lag time for temperature travel with an inlet temperature ramping step to ensure complete coke combustion with high oxygen efficiency, thus providing a rapid regeneration that permits more time for operation at desired reaction conditions.Type: GrantFiled: May 31, 2007Date of Patent: December 29, 2009Assignee: UOP LLCInventors: Leon Yuan, James L.

The inlet louvered wall and the outlet louvered wall are particularly constructed to form serial hopper-shaped structures that define the granular path. The roof-shaped flow-corrective element is systematically displaced with respect to the hopper-shaped structure by specific criteria so that problems of corrosions, plaques and stagnant zones formed to the louvered walls of the apparatus can be avoided.Type: GrantFiled: October 17, 2002Date of Patent: November 7, 2006Assignee: Industrial Technology Research InstituteInventors: Jiri Smid, Shu-San Hsiau, Jing-T.

Patent number: 7001574Abstract: A mixture of natural gas and air is converted to a C5–C19 diesel fuel-grade liquid hydrocarbon. The natural gas and air mixture is supplied to the input of a catalytic partial oxidation reactor. The carbon-containing gas output of the catalytic partial oxidation reactor is connected as an input to a first Fischer-Tropsch reactor, to thereby form a first diesel fuel grade C5–C19 liquid hydrocarbon output. A carbon-containing gas output of the first Fischer-Tropsch reactor is connected to the input of a second Fischer-Tropsch reactor, to thereby form a second diesel fuel grade C5–C19 liquid hydrocarbon output. The catalytic partial oxidation reactor contains a platinum group catalyst, a promoted platinum group catalyst, a rhodium catalyst, or a platinum promoted rhodium catalyst. Each of the Fischer-Tropsch reactors contain a catalyst that is made up of from about 3 to about 60 parts-by-weight cobalt and from about 0.Type: GrantFiled: September 20, 2002Date of Patent: February 21, 2006Assignee: Pangea Resourcces IncorporatedInventors: Steven Thomas Harford, Alessandro Giorgio Borsa, Nicholas Ernest Vanderborgh

Patent number: 7001573Abstract: By a process for removing fine dust from a fluidized-bed reactor, in particular for the oxychlorination of ethylene, is intended to permit specific control of the amount of fine dust particles in a reactor while reducing the height of the reactor and the same time filtering off the fine dust from the main stream leading to the quench. This is achieved if the fine dust inside, the reactor is removed via filter cartridges, and the reaction gas mixture is passed to the quench from the reactor dome, a part-stream in the form of a bypass stream having a predetermined fine dust fraction below a predetermined particle size being removed from the reactor in addition to the main stream.Type: GrantFiled: August 23, 1999Date of Patent: February 21, 2006Assignee: UHDE GmbHInventor: Michael Benje

Patent number: 6939823Abstract: A stripper and a stripping process for removing the flue gas carried by regenerated catalyst. A cylindrical stripper mainly comprises a degassing pipe at the longitudinal axis, a horizontal pipe connected with the lower end of the degassing pipe, several sets of inner annular baffles and outer annular baffles arranged in alternative arrangement along the vertical direction. Inner annular baffles are fixed on the degassing pipe, outer annular baffles are fixed on the inner wall of the cylinder. The degassing pipe has holes below each set of the inner annular baffles. The regenerated catalyst enters the stripper from the upper part, comes into a countercurrent and crosscurrent contact with steam from the annular steam conduit, and the stripped regenerated catalyst leaves the stripper from the bottom.Type: GrantFiled: January 29, 2004Date of Patent: September 6, 2005Assignees: China Petroleum & Chemical Corp., Research Institute of PetroleumInventors: Weimin Lu, Xieqing Wang, Xiaoxiang Zhong, Songnian Li

Patent number: 6932951Abstract: A microfabricated chemical reactor includes a plurality of lamina, an inlet port formed in at least one of the lamina, and an outlet port formed in at least one of the lamina. A continuous channel is formed in at least one of the lamina and provides fluid communication between the inlet port and the outlet port. In one configuration of the microfabricated chemical reactor, the reactor includes a particle filter disposed in the continuous channel and formed by one of the lamina, wherein the particle filter restricts flow through the continuous channel and retains catalyst or other particles within the continuous channel.Type: GrantFiled: October 30, 2000Date of Patent: August 23, 2005Assignee: Massachusetts Institute of TechnologyInventors: Matthew W. Losey, Klavs F. Jensen, Martin A. Schmidt

Patent number: 6736960Abstract: A fluid catalytic cracking unit includes a nozzle located in the bottom of a riser reactor. A first conduit provides a passageway for enabling a dispersing gas to flow therethrough and through an outlet passageway in a cap covering the end of the conduit. The outlet passageway discharges the dispersing gas into a liquid hydrocarbon feed material flowing through a second conduit spaced from and enclosing the first conduit to form an annulus therebetween, thereby providing a passageway for enabling the liquid hydrocarbon feed material to flow. A second cap covers the end of the second conduit and is spaced from the first cap thereby forming a mixing zone therebetween for mixing the liquid hydrocarbon feed and the dispersing gas. The second cap includes a continuous circular slot as an outlet passageway of the first cap and is adapted for discharging the mixture of liquid hydrocarbon feed and the dispersing gas. Hot regenerated catalyst enters the riser bottom region through a regenerator standpipe.Type: GrantFiled: March 1, 2002Date of Patent: May 18, 2004Assignee: Shell Oil CompanyInventors: Ye-Mon Chen, Hendricus Arien Dirkse
