    摘要: This invention provides a process for producing dihydronepetalactone using mixtures comprising both trans-cis nepetalactone and cis-trans nepetalactone. A reaction mixture comprising trans-cis nepetalactone and cis-trans nepetalactone is first contacted with hydrogen in the presence of at least one hydrogenation catalyst under conditions that optimise the preferential conversion of trans-cis nepetalactone to dihydronepetalactone. Cis-trans nepetalactone is subsequently converted to dihydronepetalactone by contact with hydrogen in the presence of at least one hydrogenation catalyst.

    摘要: Methods are provided for treating production fluid in an oil reservoir to reduce the amount of sulfide in the production fluid. The production fluid is treated with nitrate and/or nitrite ions in an aqueous solution that is added to an injection well that is in contact with the production well.

    摘要: A method to prevent contamination of feed line(s) and nutrient feed reservoirs(s) is disclosed. In this method the growth medium which flows from the nutrient feed reservoir through the feed line to the bioreactor contains at least one nutritional component supplied at a concentration which is inhibitory to cell growth. The inhibitory nutritional component in the growth medium prevents back growth of cells from the bioreactor into the feed line(s). The growth medium with inhibitory nutritional component is diluted prior to or at entering the bioreactor.
