Methods and compositions for asphalt rejuvenation
Roadway resurfacing often requires removal of the existing asphalt from the roadway for reuse. One method of resurfacing a roadway is hot-in-place recycling. Hot-in-place recycling employs substantial heat to remove the oxidized or aged asphalt.

The disclosure provides compositions and methods that enhance oxidized asphalt, making it more viable for use in resurfacing roadways. Accordingly, compositions comprising recycled asphalt pavement and a rejuvenating agent are disclosed. The compositions combine a rejuvenator and fresh asphalt flux to make a modified asphalt rejuvenator.

The yeast strain further includes third and/or fourth gene modifications. The recombinant yeast strain of the present invention can stably, continuously and efficiently produce extracellular cAMP by up to 9721.6 μmol/L. |

Sandwich gasification process for high-efficiency conversion of carbonaceous fuels to clean syngas with zero residual carbon discharge
gasifier and a gasification process provides a long, uniform temperature zone in the gasifier, regardless of the particle size, chemical composition, and moisture content of the fuel by sandwiching a reduction zones between two oxidation zones. The gasifier and gasification process produces a char that is more energy-dense and almost devoid of moisture, affording an additional (char) oxidation zone with a temperature that is higher than a first oxidation zone which is closer to an evaporation and devolatilization zone. As such, the additional (char) oxidation zone contributes to augmenting the reduction zone temperature, providing a favorable dual impact in improving syngas composition and near-complete conversion of the tar. |
