The biomass is regarded as a part of renewable energy sources (RES), which can satisfy energy demands. Biomass obtained from plantations is characterized by low bulk density, which increases transport and storage costs. Briquetting is a technology that relies on pressing biomass with the aim of obtaining a denser product (briquettes). In the production of solid biofuels, the technological as well as material variables significantly influence the densification process, and as a result influence the end quality of briquette. This process progresses differently for different materials. Therefore, the optimal selection of process’ parameters is very difficult. It is necessary to use a decision support tool—decision support system (DSS). The purpose of the work was to develop a decision support system that would indicate the optimal parameters for conducting the process of producing Miscanthus and willow briquettes (pre-comminution, milling and briquetting), briquette parameters (durability and specific density) and total energy consumption based on process simulation. Artificial neural networks (ANNs) were used to describe the relationship between individual parameters of the briquette production process. DSS has the form of a web application and is opened from a web browser (it is possible to open it on various types of devices). The modular design allows the modification and expansion the application in the future.

Bibliometric analysis of research trends in engineering for rural development

Engineering for Rural Development

Pedryc

et al. 2018

Abstract. Bibliometric analysis of publications allows to quantify researchers' interests in this specific topic. This method enables the identification of key authors, who are publishing in this area. It is necessary to define research trends, which have developed in this specific field. It enables to determinate the main research topics, discoveries and correlations in the global knowledge network. The purpose of this work was to identify the trends and research topics in engineering for rural development. The modified method of bibliometric analysis was used, bibliometric analysis of the key word frequency of occurrence and the linkages between the key words. The analysis was performed using bibliometirc post-conference materials of the International Scientific Conference Engineering for Rural Development in Jelgava in the years 2012-2017 downloaded from Web of Science database. The data have been processed and cleaned, then analysed in VOSviewer. This program is used for creating and graphic visualisation of bibliometric maps. VOSviewer utilized the method of "visualization of similarities" VOS. In this work the program was used to create maps of terms in the version of "thermic maps". The main research topics have been presented in the form of associated networks. The last stage was detailed topical analysis and classification into groups according to selected criteria. The provided research enabled an identification of lines of the research. The main research topics in all research period were: energy qualities of plant materials, alternative fuel (biomass, biodiesel, biogas), renewable energy sources, modelling, optimisation and stimulation of processes, mechanisation of plant production and many more. This analysis can be used as a literature review in the selected knowledge area.

“…These raw materials can be used directly as fuel or as an intermediate for further production (Table 1) [1]. Numerous studies are carried out to determine the physical and chemical properties of solid biofuels, their agglomeration and subjecting them to various thermal processes [2][3][4][5][6][7][8]. Therefore, it is necessary to determine the main directions of the research in the field of solid biofuel production.…”

Analysis of research trends in production of solid biofuels

Engineering for Rural Development

Frączek

et al. 2019

Solid biofuels can be defined as processed and unprocessed biomass. By definition it can be divided into: natural fuels (as obtained) and synthetic fuels (after mechanical and chemical treatment). Raw materials for the production of solid biofuels may include: wood, stalk plants, peat, sewage sludge and grains of cereals. These raw materials can be used directly as fuel or as a half-finished product for further production. The aim of the work was to analyze trends and research topics in the production of solid biofuels. This analysis was made using bibliometric techniques. Bibliometric analyzes allow to indicate the research topics, authors, as well as research institutions that significantly influence a given discipline. The research and analysis were carried out on scientific articles taken from the Scopus database in 2014-2018. The downloaded data have been cleaned and processed in the VOSviewer program. This program allows to analyze the frequency of occurrence of keywords in years and to present results in graphic form. Next, a detailed analysis of the content of the publications and classification according to selected criteria was carried out. The main countries that carry out research in this area are: Spain, Italy, Brazil, the Czech Republic and China. The main research areas were: Energy, Environmental Science, Agricultural and Biological Sciences, Chemical Engineering and Engineering. The most popular research topics throughout the research period were: biomass (raw materials, properties), biomass agglomeration processes (briquetting, pelleting), energy properties research, thermal biomass treatment (torrefaction, gasification and others), research on production and biochar properties and other.
