Patent number: 4544451Abstract: Briquettes made from bituminous or sub-bituminous coal or peat are produced by grinding the coal, mixing it with a binder and compacting the mixture. They are then carbonized in a continuous process in a shaft oven. The coal may be predried and the finished briquettes may be preheated, with a subsequent drying and hardening. The carbonization is effected in two stages in an indirectly heated shaft oven, with the evolved gas being taken off about at the mid-height of the oven shaft, processed, and used for heating in the second, high-temperature stage. The flue gases from this high-temperature stage are used for heating in the first stage and for preheating. The second or high-temperature stage is followed by a cooling stage where the gases evolved in the second stage, and mainly comprising hydrogen are used and circulated. The evolved gas in excess is continuously removed from the cooling circuit.Type: GrantFiled: February 16, 1984Date of Patent: October 1, 1985Assignee: Firma Carl Still GmbH & Co.

Patent number: 4523979Abstract: Retorted shale particles are recovered from a retort and delivered to a gas lift for transport to a fluidized combustor by passage, serially, through a sealing vessel, a crusher preferably operating at retort pressure, and a surge vessel. In the sealing vessel, a sealing gas is introduced, and after commingling with the shale, the gas passes countercurrently to the shale and enters the retort, thus sealing the retort gases in the retort while separating the retorted shale from the retort gases. Retorted shale from the sealing vessel is transported to a crusher, wherein the shale is reduced in size to that suitable for combustion under fluidized conditions. To prevent the crushed shale from packing, the shale is passed to a surge vessel, wherein the crushed shale is held as a fluidized bed, from which the crushed shale is continuously withdrawn at a regulated rate and introduced into the gas lift leading to the fluidized combustor.Type: GrantFiled: January 9, 1984Date of Patent: June 18, 1985Assignee: Union Oil Company of CaliforniaInventors: Roland F.

A plurality of heat exchangers are located in the housing for transferring heat in sequence to or from the crushed oil shale. The heat exchangers are spaced to define a drying zone, a preheating zone, a hydrocarbon recovery zone, and a waste heat recovery zone. A pump recirculating circuit is provided for passing waste heat recovered from the waste heat recovery zone to the preheating zone. An auxiliary heating assembly connected to the heat exchangers in the hydrocarbon recovery zone delivers sufficient heat to raise the temperature of the crushed oil shale moving through the hydrocarbon recovery zone to the critical temperature for separating hydrocarbons in vapor form therefrom.Type: GrantFiled: January 14, 1983Date of Patent: March 5, 1985Assignee: Edwards Engineering CorporationInventor: Ray C.
