Pretreatment of lignocellulosic biomass through removal of inhibitory compounds

InactiveUS20100263814A1Reduce impactPretreatment with water/steamBiofuelsXyloseDecomposition
A process for the pretreatment of lignocellulosic biomass is disclosed. The process is intended for use in connection with biomass to ethanol processes and is directed in particular to an economical removal of inhibitory compounds generated in biomass pretreatment, which are inhibitory to downstream hydrolysis and fermentation steps. The process includes the steps of heating the lignocellulosic biomass with steam to a preselected temperature, at a preselected pressure and for a preselected time to hydrolyze and solubilize hemicelluloses in the biomass; explosively decomposing the biomass into fibers; and extracting from the resulting reaction mixture a liquefied portion of the lignocellulosic biomass before or after explosive decomposition. The liquefied portion is extracted to remove compounds from the lignocellulosic biomass which are inhibitory to enzymatic cellulose hydrolysis and sugar fermentation to ethanol. For improved efficiency and economy, the inhibitory compounds are not completely removed. Furthermore, xylose has been found to be a good indicator compound for the general level of inhibitory compounds in the reaction mixture and the extraction step is therefore controlled on the basis of the xylose content in the reaction mixture. In particular, the extracting step is discontinued once a dry matter (dm) content of xylose, as monomer or oligomer, in the reaction mixture of 4% to 8% (w/w dm) is achieved. This most economically balances the practical need for inhibitory compound removal with the economical need to control and preferably minimize the costs of the overall ethanol production process.

Fixed type toughened glass crushing escape apparatus

The invention discloses a fixed type toughened glass crushing escape apparatus which is fixed on a base on toughened glass and is provided with a through hole which is perpendicular to the surface ofthe toughened glass; a hard impact rod with a pointed end is arranged in the through hole; the tail end of the impact rod, which is far away from the surface of the toughened glass, is connected witha strike cap; a resetting mechanism is arranged between the base and the strike cap; and a protective sleeve is arranged outside the cylinder of the base. The invention provides the fixed escape apparatus which can quickly crush the toughened glass without finding in the process of escape, thereby greatly shortening the escape time; because a beating mode is adopted and the impact rod is perpendicular to the surface of the toughened glass, the impact force required for crushing the toughened glass is effectively reduced, the slipping phenomenon in the process of use is avoided, and the successratio of crushing the toughened glass by weak people in the process of escape is ensured; and the design of the protective sleeve can effectively avoid the deadweight loss caused by wrongly beating.The fixed toughened glass crushing escape apparatus is suitable for quick escape by crushing the toughened glass under the emergency condition.

Collecting container, in particular for collecting packages

There is provided a collecting container. An exemplary collecting container comprises an insertion opening on the front of the collecting container that is adapted to receive objects that are dropped in and a removal opening, inside the insertion opening. The exemplary collecting container additionally comprises a receiving device arranged to receive the objects and to convey them to a storage space in the collecting container, the receiving device being movable between at least two operating states, a first operating state in which the receiving device allows an object to be received in it, while the entrance from the receiving device to the storage space is blocked, and a second operating state in which the receiving device does not allow an object to be received in it, while the entrance from the receiving device to the storage space is open, the storage space containing a filling-level measuring means that is connected to a blocking device preventing the receiving device from being opened when a defined filling level has been reached in the storage space, the receiving device comprising a roller shutter box whose receiving area is formed by at least two side walls and a bottom. The exemplary collecting container further comprises a roller shutter that is adapted to be moved in rails on the side walls in such a way that, in a first position, the roller shutter covers the entrance from the receiving area of the roller shutter box to the storage space, while the receiving area of the roller shutter box is accessible to the user and, in a second position, the roller shutter covers the insertion opening, while the entrance from the receiving area of the roller shutter box to the storage space is open, the blocking device being configured so that it can block the movement of the roller shutter.
