BIOENERGY. Latest granted patents 2016-2018. Biomass gasification
Summary
Biomass gasification is one of the most promising CHP technologies because it shows relatively high electrical efficiency compared to other CHP systems in the lower and middle range of power. This power class has high potential regarding heat demand, and therefore biomass gasification is very suitable for decentralized energy systems. Fixed-bed gasification is predominantly in this lower power range, since fluidised bed or entrained flow gasification usually calls for higher plant size for economic feasibility. In recent years, especially staged fixed-bed gasification technologies have witnessed decisive progress. However, during the gasification of biomass a large amount of tar, which are mixtures of heavy organic compounds, are generated. They may be responsible for clogging of the gasification installation and increase its failure rates. This is why there is considerable research concerning the optimization of the gasification process to reduce the amount of tar generated. The patents presented in this bulletin are aimed at overcoming some of the aforementioned problems.
The proposed bulletin is dedicated to biomass gasification and includes patents published in 2016-2018. Research methodology is available on the Advanced Energy Technologies website. The patent bulletin includes 630 patent documents. The patents were granted in 25 patent offices around the world. 363 applicants from 24 countries participated in the development of the inventions. 635 subgroups of the International Patent Classification were encountered in the patent documents.
Key Highlights
The bulletin contains statistical data on the distribution of patent documents by years, by patent offices and by applicant countries, applicant-related data (residents and non-residents), data on the most frequently mentioned International Patent Classification divisions (sections, classes, subclasses, groups, and subgroups). The top three patent offices that granted the largest number of patents were USPTO (US), CNIPA (CN) and EPO.
From the analysis of texts of patents presented in this bulletin, detailed information is extracted for each of the unified indicators, which include: technical problems, types of inventive solutions employed, belonging of a patent document to one or other technological segment. The results of the statistical processing of this data for the entire array of the patents examined are summarized in the correspondingly-named diagrams and tables. In addition to that, a list of the top 10 groups of patent documents with identical unified indicators is provided, where the groups are sorted by the number of patent documents and include ID numbers and applicant names of the documents.
The following information can be found for the top 10 applicants: breakdown of patents by problems, IPC sections, patent offices, technological indicators, as well as the estimation of their share in the established intellectual property market. The 10 leading applicants by the number of patent documents were: Wuhan Kaidi Engineering Technology Research General Institute Co., Ltd. (CN), General Electric (US), RES USA LLC (US), Sunshine Kaidi New Energy Group Co. Ltd (CN), Neste Oyj (FI), Rentech Inc. (US), Air Liquide (FR), Commissariat à l'énergie atomique et aux énergies alternatives (FR), Linde AG (DE), ExxonMobil Research and Engineering Company (US).
The top prominent documents section includes three lists of the top 10 patents having the highest bibliographical rating, the largest number of IPC sections, and the shortest patent pending time.
A list of all of the documents reviewed, arranged by the top 10 groups of patent documents with identical unified indicators and by patent offices with the indication of the ID numbers of the granted patents are provided in the conclusive part of the bulletin.
