Process are provided which are effective for controlling medium conductivity during fermentation of a CO-containing gaseous substrate while providing an STY of about 10 g ethanol/(L&#xb7;day) or more. The process includes balancing medium conductivity, specific carbon uptake or cell density levels.

There is disclosed a system that, when in operation, evaluates speech, for example evaluates a speech signal generated using a microphone to record an oral utterance. The system comprises: a user device that receives a user-defined text; and a processing unit that is operatively coupled to the user device, wherein the processing unit: refines the user-defined text to form a base text having a plurality of base text-units; defines at least one path traversing the plurality of base text-units, wherein the at least one path traverses at least one of the plurality of base text-units sequentially; receives an utterance for the user-defined text from the user device; processes the utterance to generate an interpretation text having a plurality of interpretation text-units; maps the plurality of interpretation text-units to the plurality of base text-units; assigns a score to the at least one path based on the mapped quality; identifies a traversed path from the at least one path; and calculates the assigned score associated with the traversed path to evaluate the speech.

A process and apparatus are provided for reducing content of tar in a tar containing syngas. The process includes contacting the tar containing syngas with a molecular oxygen containing gas in a first reaction zone to produce a gas mixture. The gas mixture is passed through a heat treatment zone maintained at a temperature between about 900&#xb0; C. to about 2000&#xb0; C. for a contact time of about 0.5 to about 5 seconds. In this aspect, at least a portion of the tar undergoes at least partial oxidation and/or cracking to produce a hot syngas.

A process provides high ethanol productivity levels during fermentation of a CO-containing substrate. The process controls CO-substrate feed rates and cell density to avoid culture upset and CO inhibition. The process includes fermenting a CO-containing gaseous substrate to obtain a target cell density and a target CO feed rate, and then periodically reducing and increasing the CO feed rate.

Process for fermenting co-containing gaseous substrates

A process and apparatus is provided which are effective for improving CO mass transfer. The process includes introducing syngas into a reactor vessel through a gas sparger located below a liquid level in the reactor vessel. The syngas being introduced at a flow rate effective for maintaining a pressure inside of the reactor vessel of at least about 1 psig. An agitation energy of about 0.01 to about 12 kWatts/mmedium is provided. The process is effective for providing a volumetric CO mass transfer coefficient of about 100 to about 1500 per hour.

A process is provided for fermenting CO-containing gaseous substrates in a low phosphate medium. The process includes blending a liquid medium that includes at least one transition metal element with a liquid medium that includes at least at least one other transition metal element and one non-metal element to provide a fermentation medium. The process is effective for preventing precipitation of one or more transition metal elements with one or more non-metal elements. The fermentation medium used in the process is prepared in a way that requires significantly lower amounts of water and reduced levels of phosphate.

A process and apparatus are provided for gasification of a carbonaceous material. The process produces a raw syngas that can be further processed in a tar destruction zone to provide a hot syngas. The process includes contacting said carbonaceous material with molecular oxygen-containing gas in a gasification zone to gasify a portion of said carbonaceous material and to produce a first gaseous product. A remaining portion of the carbonaceous material is contacted with molecular oxygen-containing gas in a burn-up zone to gasify additional portion of the carbonaceous material and to produce a second gaseous product and a solid ash. The first gaseous product and said second gaseous product are combined to produce a raw syngas that includes carbon monoxide (CO), carbon dioxide (CO) and tar. The raw syngas is contacted with molecular oxygen containing gas in a tar destruction zone to produce said hot syngas.
