Abstract: Tungsten carbide catalysts are used in preparation of ethylene glycol by hydrogenating degradation of cellulose. The catalyst includes tungsten carbide as main catalytic active component, added with small amount of one or more transition metals such as nickel, cobalt, iron, ruthenium, rhodium, palladium, osmium, iridium, platinum, and copper as the second metal, supported on one or more porous complex supports such as active carbon, alumina, silica, titanium dioxide, silicon carbide, zirconium oxide, for conversion of cellulose to ethylene glycol. The catalyst realizes high efficiency, high selectivity, and high yield in the conversion of cellulose to ethylene glycol at the temperature of 120-300° C., hydrogen pressure of 1-10 MPa, and hydrothermal conditions. Compared to the existing industrial synthetic method of ethylene glycol using ethylene as feedstock, the invention has the advantages of using renewable raw material resources, environment friendly process, and excellent atom economy.

Abstract: This invention provides fire prevention and detection for heavy-duty and medium-duty commercial and military vehicles by ensuring the engine is automatically and immediately shut down upon the occurrence of a catastrophic event that may lead to a fire. The shutdown is achieved through the isolation of the vehicle batteries and alternator and the disconnecting of those devices from all electrical circuits. Anomalies that cause the shutdown and disconnect include battery and vehicle load currents that are outside a preset range, excessive temperatures, detection of smoke in the drive compartment or sleeper, or detection of a frontal impact accident or vehicle rollover. Once disconnected, the battery contactor must be manually reset in order to restore electrical power to the vehicle.
