    摘要: An electronic circuit having built-in self testing capabilities for optimizing power consumption. Typically, the electronic circuit includes a component circuit that operates at some known or unknown optimal operating power level. Further, the electronic circuit includes a power supply coupled to the component circuit such that the power supply provides power to the component circuit. Further yet, the electronic circuit includes a test circuit coupled to the component circuit and coupled to the power supply. The test circuit is operable to monitor the power supplied to the component circuit and operable to control the power supply. In an iterative manner, the test circuit reduces the power supplied to the component circuit until the power supplied to the component circuit is operating at the optimal operating power level.

    摘要: A process for shape-selective hydrocarbon conversion that involves initially contacting a feed stream which includes an alkylaromatic compound and a co-feed of water, under conversion conditions with a catalytic molecular sieve. Preferably, the catalytic molecular sieve has been modified by being ex situ selectivated with a silicon compound. After an effective amount of time, the water co-feed is omitted from the feed stream and the hydrocarbon conversion process is continued. Optionally, the catalytic molecular sieve can also be in situ trim-selectivated.

The ex situ selectivation method is also described, including the use of low volatility organic carriers for the selectivating agent. Also, a method for moderate steaming of the ex situ selectivated molecular sieve. Also a method for in situ trim-selectivating the ex situ selectivated catalytic molecular sieve. Also described is the process for shape selective hydrocarbon conversion comprising contacting a hydrocarbon feedstream under conversion conditions with the modified catalytic molecular sieve.
