    摘要： A concentrating solar power collector plant is provided in which a pressurized solar power receiver with an associated gas turbine and a low-pressure solar power receiver are used together with a common thermal energy storage system. Exhaust from the gas turbine is connected to the thermal energy storage system to deliver residual heat to the thermal energy storage system in addition to that received from the low-pressure solar power receiver. The pressurized solar power receiver may be a separate unit from the low-pressure receiver and at least some heliostats are controlled to redirect reflected solar energy from one solar power receiver to the other. The pressurized solar power receiver may alternatively be combined with the low-pressure receiver in a single unit having a heat receiving part of a high-pressure receiver and a flow passage for heating air between an inlet and an outlet to form the low pressure receiver.

    摘要： The invention provides a method of modifying soluble xylan which contains glucuronic acid and/or arabinose side chains so that it can be adsorbed onto other substrates. The method includes the steps of enzymatically modifying the xylan by selectively removing glucuronic acid and/or arabinose side chains from the xylan with α -D-glucuronidase and/or α -L-arabinofuranosidase, and allowing the modified xylan to adsorb onto the substrate. The substrate may be a cellulosic substrate like pulp or paper or a non-cellulosic substrate. The enzymes are able to remove a sufficient number of the xylan side chains so as to decrease water solubility of the xylan, induce xylan precipitation and allow adsorption of the xylan onto other substrates. A pulping process which incorporates modification of xylan and adsorption onto cellulosic material is also provided, as are products which contain the modified xylan.
