Data for: CO2 conversion into synthetic natural gas
Description
This dataset contains information regarding the patented methods (both application and granted patents) for the carbon dioxide conversion into substitute natural gas. The database used for data mining is Espacenet (a free-of-charge database provided by the European Patent Office), accessed on Oct. 21, 2021. The attached file contains information related to title, inventors, applicants, publication number, earliest priority, IPC, CPC, publication date, earliest publication, and family number. The patent search was carried out by means of keywords (in the full-text search field) and classification codes. Both IPC (International Patent Classification) and CPC (Cooperative Patent Classification) codes were used. Definition of the classification codes used C10L 3/08: Production of synthetic natural gas C10K: Purifying or modifying the chemical composition of combustible gases containing carbon monoxide C10G: Cracking hydrocarbon oils; production of liquid hydrocarbon mixtures, e.g., by destructive hydrogenation, oligomerization, polymerization; recovery of hydrocarbon oils from oil-shale, oil-sand, or gases; refining mixtures mainly consisting of hydrocarbons; reforming of naphtha; mineral waxes. Combination sets: (C07C 1/12; C07C 9/04)
