以秸秆资源化利用技术领域授权发明专利为研究对象,从技术发展年度趋势、技术集中度、重要专利权人及其关注技术、重点专利等维度,对该领域专利数据进行挖掘和可视化分析。研究表明,该领域技术在经历了萌芽期、推动期、上升期后,目前已进入发展期。研发重点集中在C05G、C05F等IPC小类中,其中C05G保持着较高的研发活跃度,A23K、A01G处于平稳发展期,而C05F和C12P有进入技术衰退期的迹象。该领域技术优势单位为高校和科研院所,关注技术集中于秸秆变性处理,发酵酶解,制备肥料、氢气、微生物油脂、乙醇,创制秸秆厌氧发酵装置、成型装置、还田装置。核心专利的主要技术功效为加速半纤维素的降解,提高纤维素含量,实现纤维素、半纤维和木质素分级转化等。
Taking patents granted for straw resources utilization as the research object, this paper digs and visualizes the patent data in this field from the perspectives of annual trend of technology development, technology concentration, important patentees and their technologies of interest, and key patents. Research shows that in the field of technology has gone through a period of infancy, promotion, rising period, has now entered the development phase. R & D focuses on IPC subsets such as C05G and C05F. Among them, C05G maintains a high R & D activity, while A23K and A01G are in steady development while C05F and C12P have signs of entering a technology recession. The technical superiority of the field units for universities and research institutes, focusing on technology focused on the denaturation of straw, fermented enzymatic hydrolysis, preparation of fertilizers, hydrogen, microbial oil, ethanol, create straw anaerobic fermentation device, forming device, back to the device. The main technical effect of the core patent is to accelerate the degradation of hemicellulose, increase the content of cellulose, and realize the grading conversion of cellulose, hemicellulose and lignin.
