A carbon sink enhancement method based on oyster-integrated aquaculture is performed as follows. Oysters with similar size and appearance are selected, washed and evenly spread onto a bottom of an incubator, to which 5-15° C. seawater is added. A rope is fixed on an upper side wall of the incubator.seedlings are spacedly clamped on the rope for spaced hanging culture. A wet weight ratio of the oyster to theseedlings is 6-8:1. The incubator is placed under sunlight for mixed culture, during which the incubator remains closed without water replacement. The oysters or theseedlings are taken out when the oyster reaches a meat yield of 10% or more or a length of theseedlings is larger than 100 cm. Seawater samples are collected to detect water quality parameters for carbon sink assessment.

The present invention relates to a preparation process for a Cu-based catalyst and use of the Cu-based catalyst as the dehydrogenation catalyst in producing a hydroxyketone compound such as acetoin. Said Cu-based catalyst shows a high the acetoin selectivity as the dehydrogenation catalyst for producing acetoin.

Preparation process for Cu-based catalyst and use thereof

The present invention relates to a Cu-based catalyst, a preparation process thereof and its use as the dehydrogenation catalyst in producing a hydroxyketone compound such as acetoin. Said Cu-based catalyst contains copper, at least one auxiliary metal selected from metal of Group IIA, non-noble metal of Group VIII, metal of Group VIB, metal of Group VIIB, metal of Group IIB and lanthanide metal of periodic table of elements, and an alkali metal, and further contains at least one ketone additive selected from a ketone represented by formula (II) and a ketone represented by formula (II'). Said Cu-based catalyst shows a high the acetoin selectivity as the dehydrogenation catalyst for producing acetoin.R1-C(&#x2550;O)&#x2014;CH(OH)&#x2014;R2&#x2003;&#x2003;(II)R1-C(&#x2550;O)&#x2014;CH(&#x2550;O)&#x2014;R2&#x2003;&#x2003;(II&#x2032;) In formulae (II) and (II&#x2032;), each group is defined as in the description.
