摘要:
Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful products, such as fuels. For example, systems are described that can use feedstock materials, such as cellulosic and/or lignocellulosic materials, to produce ethanol and/or butanol, e.g., by fermentation.
摘要:
The present invention relates to a method of manufacturing one or more chemical products in which a chemical reaction is performed by causing one or more reagents to flow along the inside of a tube disposed in a radiation zone of a furnace. In the method, at least a portion of the tube is caused to vibrate so as to limit the deposition of reaction by-products on the inside wall of the tube. More particularly, the tube can be vibrated at a frequency lying in the range 50 Hz to 2000 Hz. The invention also provides apparatus for performing the method of the invention, which apparatus comprises a furnace including a radiation thermal enclosure through which at least one tube passes, which tube is provided with at least one excitation means suitable for generating tube vibration.

This invention relates to a new manner of carrying out chemical reactions by injection of selected forms of energy into the reaction zone by novel means. By applying this principal, many new processes result with application in a large number of different industries. The new process is generally capable of operation at room temperatures, which has advantages in the creation of certain sensitive products including uniformly doped semi-conductors, new catalysts, pure gases, high purity materials of any kind, controlled coatings, new polymers, combustion enhancement, difficult separation, petroleum refinery operations, and carrying out any reaction in which the injection of specific energy types is helpful.
