Patent number: 8444925Abstract: A lignocellulosic biomass saccharification pre-treatment device for easily recovering ammonia water to be used in a pre-treatment for saccharification of a lignocellulosic biomass and recycle use. The device has a mixing unit 2 mixing lignocellulosic biomass and ammonia, a heating unit 3 heating the mixture, a separation unit 4 separating ammonia gas from the mixture to obtain a biomass-water mixture, and a transfer unit 6 transferring the biomass-water mixture to a later process. An ammonia water supply unit 8 supplies ammonia water to the mixing means 2. An ammonia recovery unit 20 recovers ammonia gas as ammonia water. A heat-of-dissolution recovery unit 24 recovers heat-of-dissolution generated when ammonia gas is dissolved in water. A heat pump unit 30 generates heat to be supplied to the heating unit 3 using at least the heat-of-dissolution as a heat source.Type: GrantFiled: November 25, 2009Date of Patent: May 21, 2013Assignee: Honda Motor Co., Ltd.Inventor: Tsuyoshi Baba

Patent number: 8444939Abstract: A reactor module for Fischer-Tropsch synthesis having a generally rectangular reactor block with a stack of plates defining flow channels for coolant and flow channels for the synthesis reaction arranged alternately in the block. The synthesis flow channels extend in a generally vertical direction between upper and lower faces of the reactor block and are defined by plates in combination with either bars or sheets such that each channel is of width no more than 200 mm. The coolant flow channels are oriented in the same direction, and communicate through distributor chambers with inlet and outlet ports at side faces of the reactor block. A plant may contain a multiplicity of such reactor modules operating in parallel, the modules being interchangeable and replaceable. The temperature control is enhanced by allowing the coolant flow to be parallel to the synthesis gas flow.Type: GrantFiled: September 24, 2008Date of Patent: May 21, 2013Assignee: CompactGTL plcInventors: Michael Joseph Bowe, Clive Derek Lee-Tuffnell
