“…Hydrogen can be produced from a wide variety of catalytic processes employing mainly nickeland cobalt-based catalysts, like steam reforming of different carbon feedstocks (e.g., methane, methanol, ethanol, acetic acid) [95][96][97], methane dry reforming [98,99], partial oxidation of methane and other hydrocarbons [95,100] or biomass gasification [101]. For economic and technical reasons, steam reforming of natural gas (mainly composed of methane, CH 4 ) using Ni-based catalysts (usually supported on Al 2 O 3 ) remains the preferred route for industrial hydrogen production [102,103].…”

The phenomenon of “Non-Faradaic Electrochemical Modification of Catalytic Activity (NEMCA)” or “Electrochemical Promotion of Catalysis (EPOC)” has been extensively studied for the last decades. Its main strength, with respect to conventionally promoted catalytic systems, is its capability to modify in-situ the activity and/or selectivity of a catalyst by controlling the supply and removal of promoters upon electrical polarization. Previous reviews have summarized the main achievements in this field from both the scientific and technological points of view. However, to this date no commercial application of the EPOC phenomenon has been developed, although numerous advances have been made on the application of EPOC on catalyst nanostructures (closer to those employed in conventional catalytic systems), and on the development of scaled-up reactors suitable for EPOC application. The main bottleneck for EPOC commercialization is likely the choice of the right chemical process. Therefore, from our point of view, future efforts should focus on coupling the latest EPOC advances with the chemical processes where the EPOC phenomenon offers a competitive advantage, either from an environmental, a practical or an economic point of view. In this article, we discuss some of the most promising cases published to date and suggest future improvement strategies. The considered processes are: (i) ethylene epoxidation with environmentally friendly promoters, (ii) NOx storage and reduction under constant reaction atmosphere, (iii) CH4 steam reforming with in-situ catalyst regeneration, (iv) H2 production, storage and release under fixed temperature and pressure, and (v) EPOC-enhanced electrolysers.

“…Despite advantages, the gasification process still lacks studies regarding raw materials and technology implementation. In this scenario, the private sector could be the driving force in the search for solutions for the gasification process, based on data generated in decades of technological survey research carried out both in the industrial and academic environments to identify possible opportunities or challenges that need further studies and investments (Hossain, & Charpentier, 2015). This article proposes translational research of technological applications for waste gasification in Brazil.…”

Environmental issues weigh heavily on international economic relations with demands for stricter environmental regulations for the deforestation of forest areas and the generation of urban solid waste (USW). These demands drive research in the area of USW to reduce the waste volume and to its use in various fields such as power generation. In 2020, the legal milestone of the National Solid Waste Policy (NSWP) in Brazil was updated, opening space for private initiative in the management of systems related to USW. This work aims to carry out a technological prospection on gasification developed in Brazil using translational research and databases from CAPES, Web of Science, and ESPACENET portals to verify research incentives in universities, public and private, from 1984 to 2022. The search strategy first maps the search for dissertations (master's) and theses (doctoral) documents, called non-patented literature on biomass gasification, and it verifies the relationship with the production of articles in the area, and secondly, it correlates with the production of gasification patent documents. Implementation trends and factors that influenced gasification research were analyzed which generated 357 academic documents (thesis and dissertation), petitioners of patent applications and granted patents in Brazil, and academic research that reached society in the format of 189 articles and one patent.

“…Biomass, the total of non-fossil organic materials that have intrinsic chemical energy content, derived from carbon based materials and mainly comprised of agricultural residues, animal manures, agro-industrial residues, municipal solid wastes and harvests from forests (Balat & Ayar, 2005;Hossain & Charpentier, 2015). Biomass energy is the largest source of renewable energy representing 77.78% of renewable global energy supply and 10% of global primary energy supply (WEC, 2016).…”

Biomass fuel is the most important form of renewable energy in many parts of the world including Bangladesh. Its extraction is considered as a leading cause of forest degradation of developing countries like Bangladesh. Its consumption, collection and preference patterns are thus very important indicators of overexploitation of forest. On the other hand, forests are meager in mainly northern region of Bangladesh. Reliable data and information are scanty on biomass fuel in Bangladesh, particularly in formulating its proper management plan. The aim of this study was to conduct a comparative study on the aforesaid patterns in forest and non-forest areas of northern region of Bangladesh. The study was carried out by adaptive multistage random sampling technique. A total of 90 households (45 from forest area, 45 from non-forest area) were selected randomly and based on the monthly income the households were categorized into rich, medium, poor groups. The consumption of biomass fuel was found to be differed significantly between forest (2.10 kg/capita/day) and non-forest (1.71 kg/capita/day) area. Forest, market, agriculture, homestead and roadside plantation were identified as sources of biomass fuel, and the contribution of each sources varied significantly between the areas except market. In forest area, maximum amount of biomass fuel was collected from nearby forests (44%) and poor households collected 78% of biomass fuels from the same sources. In non-forest area, roadside plantation (31%) and homesteads (24%) were the major sources of biomass fuel, and poor households collected biomass fuel mainly from roadside plantations (75%). Stems, branches, leaves, agricultural residues and cow dung were used as biomass fuel in both areas but the consumption of each biomass fuel types varied significantly except leaves. Women were identified as major biomass fuel collector and most of the biomass fuel was found to be collected during morning to noon in both areas. Most commonly used fuelwood species was Shorea robusta in forest area and Eucalyptus camaldulensis in non-forest area. The findings of this study will help policymakers to take steps in halting deforestation as well as meeting the villager’s needs for biomass fuel. Keywords: Bangladesh, biomass fuel, forest degradation, fuelwood, homesteads, natural forests
