  • Patent number: 9512364
    Abstract: This invention relates to a process for thermochemically transforming biomass or other oxygenated feedstocks into high quality liquid hydrocarbon fuels. In particular, a catalytic hydropyrolysis reactor, containing a deep bed of fluidized catalyst particles is utilized to accept particles of biomass or other oxygenated feedstocks that are significantly smaller than the particles of catalyst in the fluidized bed. The reactor features an insert or other structure disposed within the reactor vessel that inhibits slugging of the bed and thereby minimizes attrition of the catalyst. Within the bed, the biomass feedstock is converted into a vapor-phase product, containing hydrocarbon molecules and other process vapors, and an entrained solid char product, which is separated from the vapor stream after the vapor stream has been exhausted from the top of the reactor.

  • Patent number: 9505983
    Abstract: An adjustable chargehole closure for adjusting the closure cover of a charging hole in a coking oven chamber. The adjustable chargehole closure has as an inner frame for a closure cover, and the frame can be rotated both with respect to the closure cover and with respect to an outer frame, designed asymmetrically with respect to a vertical plane, so that the closure cover is displaced along a longitudinal axis when the inner frame is rotated in the horizontal plane. The position of the charging hole opening and the closure cover present therein on the ceiling of a coking oven chamber can thereby be changed without requiring construction measures on the ceiling of a coking oven chamber. The capability is in particular advantageous in order to match the position of the charging hole cover to the precise charging position of the charging machine.

  • Patent number: 9458383
    Abstract: A method and a device for breaking up a fresh and hot coke charge in a receiving trough having mobile plate segments, the coke charge being conveyed to a quenching tower in the receiving trough of a flatbed transport car in which the coke charge is cooled down to ambient temperatures by mobile plate segments so that the coke structure is broken up and crevice-type cavities are formed in the compacted coke charge. These crevice-type cavities then allow an increased amount of water to flow into the interior of the coke charge during the subsequent quenching step, resulting in a high profitability of the method, a higher coke quality and a reduced burden on the environment due to reduced quenching times and lower water consumption. A device for carrying out the method is also disclosed.
