According to data from the Tianyancha app, Sinopec (600028) has newly obtained an invention patent grant. The title of the patent is “A reactor, reaction system, and method for synthesizing carbonates, as well as the carbonates obtained therefrom”; the patent application number is CN202111215749.4, and the grant date is October 31, 2025. Patent abstract: The present invention discloses a reactor, a reaction system, and a method for synthesizing carbonates, as well as the resulting carbonates. A catalyst bed is arranged in the middle of the reactor; above this catalyst bed, there are a filtering screen and a liquid-phase extraction component. The liquid-phase extraction component is of hollow ring shape, and a liquid-phase outlet pipe is provided between this component and the outlet for the liquid-phase reaction products, thereby allowing the liquid-phase reaction products collected by the extraction component to be discharged. The reaction system includes a mixer, a dissolver, the reactor, the buffer tank, and a circulation pump connected in sequence. The present invention solves problems such as catalyst loss, clogging of the wire mesh, too low liquid flux in the catalyst bed, large amounts of gas entrained in the circulating liquid, and gas entrapment in the circulation pump in existing carbonate production devices, and can be applied to the industrial production of carbonates. Since the beginning of this year, Sinopec has obtained 3,632 new patent approvals, a 12.02% decrease compared to the same period last year. Based on the company’s financial figures for the first half of 2025, the company invested 6.186 billion yuan in research and development during this period, representing a 3.05% increase compared to the previous year.
