  • Publication number: 20090104676
    Abstract: This invention is a process for managing the gas flow through a plurality of bioconversion modules that provide a gas liquid interface. The conversion modules provide the gas liquid interface across an activated surface that converts at least some of the gas components into desired liquid products. Arrangement of the modules and control of gas flow in accordance with this invention enhances the utilization of the gas and the production of desired liquid products by adjusting the flow area to compensate for changes in the volume of the feed gas. Improved control of the gas velocity through the bioconversion modules eliminates problems of liquid condensation and flow maldistribution. The process may sequence the modules to mitigate time variation in microorganism activity and incorporate additional periodic process steps.

  • Publication number: 20090017514
    Abstract: Ethanol and other liquid products are produced by contacting syngas components such as CO or a mixture of CO2 and H2 with a surface of a membrane under anaerobic conditions and transferring these components in contact with a biofilm on the opposite side of the membrane. These steps provide a stable system for producing liquid products such as ethanol, butanol and other chemicals. The gas fed on the membrane's gas contact side transports through the membrane to form a biofilm of anaerobic microoganisms that converted the syngas to desired liquid products. A liquid impermeable layer of the membrane assists in establishing direct gas phase contact syngas components with the microorganisms. The system can sustain production with a variety of microorganisms and membrane configurations.

  • Publication number: 20080204080
    Abstract: An inverting flip-flop (F/F) circuit type monostable-bistable transition logic element (MOBILE) circuit that uses resonant tunneling diodes (RTDs) and can prevent a malfunction caused by low peak-to-valley current ratio (PVCR) characteristics of the RTD includes an input data conversion circuit and an inverting F/F circuit. The input data conversion circuit receives input data and converts a logic level of the input data according to a logic level of output data of the MOBILE circuit. The inverting F/F circuit inverts a logic level of data output from the input data conversion circuit and outputs the output data. Accordingly, even when a logic level of input data changes from LOW to HIGH, the logic level of output data can be maintained HIGH in the inverting F/F type MOBILE circuit constructed using silicon semiconductor based RTDs with a small PVCR. Therefore, it is possible to enhance the performance of the inverting F/F circuit type MOBILE circuit.

  • Publication number: 20080196847
    Abstract: A process of treating a lignocellulosic material includes a pre-extraction step in which hemicellulose is extracted from the lignocellulosic material. Then, in a solvent pulping step, the lignocellulosic material is separated into pulp by contacting the lignocellulosic material with a cooking liquor comprising a solvent. In one embodiment, the solvent has a boiling point of at least about 150° C. In another embodiment, the cooking liquor comprises a mixture of solvent and water.
