  • Patent number: 11980844
    Abstract: The present invention relates to a method for carbon dioxide capture and concentration by partitioned multistage circulation based on mass transfer-reaction regulation. In the present invention, multiple means such as multistage circulating absorption, intelligent multi-factor regulation, pre-washing and cooling, inter-stage cooling, post-stage washing, slurry cleaning, cooling water waste heat utilization, small-particle-size and high-density spraying, external strengthening field such as a thermal field/ultrasonic field/electric field, and catalysis by composite catalyst are adopted, so that the target for low cost, low energy consumption, stability and high efficiency is realized. The secondary pollutants are effectively inhibited while carbon dioxide is efficiently captured; meanwhile, high-efficiency capture, low-energy desorption, and high-purity concentration of carbon dioxide are implemented.

  • Patent number: 11946088
    Abstract: The disclosure discloses a method for processing oil crops with rhodotorula, and belongs to the technical field of fermentation. The method includes the step of inoculating the rhodotorula (such as Rhodotorula mucilaginosa, Sporidiobolus salmonicolor and Rhodotorula glutinis) that can produce carotenoid into a fermentation medium that contains oil-rich oil crops for solid state fermentation to obtain oil and oil crop meal rich in carotenoid. The carotenoid as a fermentative metabolite of the rhodotorula has bioactivities of resisting oxidation, preventing vascular sclerosis, enhancing immunity and preventing cancers. Contents of carotenoid in the oil and oil crop meal acquired by the method can be up to 9.071 ?g/g and 8.062 ?g/g correspondingly.

  • Patent number: 7307036
    Abstract: A highly active alpha-olefin polymerization catalyst component is disclosed. In the presence of a co-catalyst, the catalyst component is useful for the production of LLDPE resins. The catalyst component is produced by a method whereby organic silicon compounds are reacted with a transition metal complex and active transition metal species is deposited on a silicon-containing MgCl2 that is prepared in situ in the presence of the organic silicon compounds.
