The graphene-based carbon dioxide scavenger has the following components and contents: SiC:20-23.5 wt%,CuO:0.1-0.3 wt%, cO2:20-30 wt%, Fe(OH)2: 20-34 wt%, Mn:1.03-0.14 wt%, Zn:0.03-0.04 wt%, Ag:0.003-0.004 wt%, Wu:100-150ppm, and the balance being excess NH3 and CO2 generated in the process. The deposition process of introduced carbon dioxide gas is controlled for 1-50 minutes; preferred 5-10 min, wherein the external temperature is kept at 10 to 100 DEG C; preferred 25 degrees. The beneficial effects of the preparation method are that: ammonia gas and carbon dioxide are utilized; the graphene powder capable of reacting is added and combined to prepare the fine degradation trapping agent, suchthat the capturing requirement on greenhouse gas can be well met, the multi-time use can be achieved, no by-product is generated, and the domestic and overseas market requirements can be well met.

A method for preparing water-solubility ginkgo powder
InactiveCN101156703BHistoricalSufficiently retain the nutritional ingredients of medicinal dietMilk preparationFood preparationCyanide compoundSolubility
The invention relates to a production method of a water soluble gingko powder, which belongs to the gingko processing technical field. The invention takes fresh gingko as the raw materials, gingko seeds are crushed with water after being shelled, the gingko starch and the destarch gingko solution are respectively obtained through precipitation separation, the gingko starch obtains the gingko starch hydrolyzed solution through the enzymolysis of amylase and pullulanase together, and the gingko starch hydrolyzed solution and the destarch gingko solution adopt homogenization treatment and spray drying after being mixed, so as to produce water soluble gingko powder of the residual of non-cyanide. The water soluble gingko powder holds the gingko fragrance and the nutrition component, thereby the invention has great significance to the comprehensive utilization of gingko resources.
