    Abstract: The present invention successively performs hydrodeoxygenation (HDO) and dehydration so that, unlike that of a conventional technique, an alpha-olefin is prepared to have high selectivity, and not an olefin having a double bond at sites other than the alpha position. In addition, according to the present invention, selectivity for alpha-olefin can be further improved under optimal reaction conditions, and an alpha-olefin can be stably prepared with an extended preparation time of up to 180 hours.

A testing system may use test case data describing a first test case failed by a first build of the software application, the first build generated by a first commit operation of the plurality of commit operations to execute a fault localization operation, the fault localization operation to identify a first suspect program element of a first build. The testing system may use the first suspect program element and commit data to select a second commit operation from the plurality of commit operations. The testing system may determine an error-inducing commit operation from the plurality of commit operations and executing a corrective action.

  • Patent number: 10766019
    Abstract: The present invention relates to an olefin metathesis reaction catalyst where rhenium (Re) oxide or molybdenum (Mo) oxide is supported, as a catalyst main component, on a surface-modified mesoporous silica or mesoporous alumina support, and a preparation method therefor. The olefin metathesis reaction catalyst of the present invention allows highly efficient metathesis of long-chain unsaturated hydrocarbons having at least eight carbons at a low temperature of 150° C. or lower. The catalyst can be separated readily from reaction solution, regenerated at a low temperature of 400° C. or lower by removing toxins accumulated on it during the metathesis reaction, and used repeatedly in metathesis reaction many times, thereby being made good use in commercial olefin metathesis processes.
