With the increasing role of hydrogen in global market, new ways production are being sought and investigated. One possible solutions might be plasma pyrolysis methane. This approach provides not only desired hydrogen, but also valuable carbon-containing products, e.g., carbon black C2 compounds. review gathers information from last 20 years on different reactors that were investigated context methane pyrolysis, emphasizing products can obtained through this process.
Agriculture affects both the quantity and quality of water available for other purposes, which becomes problematic, especially during increasingly frequent severe droughts. This requires tapping into resources that are typically neglected. One such resource is a by-product anaerobic digestion, in moisture content exceeds 90%. Application hydrothermal carbonization process (HTC) to this residue could partially remove organic inorganic material, improve dewatering, decrease overall solid mass,...
This study examines a solid recovered fuel gasification process in the context of regional, clean energy supply from an affordable source. The examination this approach was performed under various equivalence ratios and load regimes. A unique cross/updraft reactor with fixed (sliding) bed over circular grate tangential media intake utilised. technology is perspective waste-to-energy waste-to-materials production. investigated parameters included producer gas quality purity, overall...
Properties of miscanthus hydrochars obtained through wet torrefaction were studied.The process was carried out in three different temperatures -180, 200 and 220 °C with four ratios water to biomass -3:1, 6:1, 12:1 16:1.The solid products characterized respect their fuel properties.The best results for the temperature showed a noticeable improvement properties -especially grindability lowered ash content.The influence ratio not so explicit while high an all mentioned properties, low allowed...
In this paper, a matter of biomass torrefaction and gasification is closely looked at from different points view during low load equivalence ratio regime, defined as λ=0.08. Considering gas production, the hot efficiency conversion (30%) its energy content (4.14 MJ m−3) were not quite satisfying, however, fact was compensated by an interesting yield biochar. This material generated in 0.387 0.314 rates for + processes, respectively, which, both cases, represents attractive, alternative...
Sewage sludge is a waste from the water treatment installations. It used in agriculture. However, due to various environmental restrictions, not all of sewage can be utilized within that sector. Using this resource as sustainable energy source might an interesting alternative landfilling. Some fuel-related properties make it difficult fuel without preprocessing. Torrefaction promising pretreatment technique could prove itself suitable for improving sludge. Additives obtaining some further...
The gasification and torrefaction of sewage sludge have the potential to make thermal utilization fully sustainable, thus limiting use expensive fossil fuels in process. This includes sustainability terms electricity consumption. Although a great deal work has been performed so far regarding some investigations area its torrefaction, there is still gap influence on subsequent gasification. study presents results from tests, pilot scale reactor, as well two consecutive steam an allothermal...
To make a beer there are four essential ingredients needed: water, malt, hops, and yeast. After brewing process, the main wastes spent grains. These often used as additions to fodders in animal husbandry. This study presents preliminary results of an investigation aiming determine feasibility alternative use grains potential source solid fuel. energy could breweries partly sustainable terms their supply. Such approach may be feasible especially large scale industrial breweries. encouraging...
In order to utilise energy-rich solid waste, its liquid conversion into valuable hydrocarbon (HC) chains is one of the ways followed worldwide decrease oil processing and waste landfilling at same time.The unique fixed bed updraft gasification reactor with an oscillating circular grate, situated in VŠB -Technical University Ostrava, Czech Republic, can generate up 90 m 3 •h-1 CO H 2 -rich synthetic gas.Such mixture suitable for gas Fischer-Tropsch Micro Catalyst Bed (F-T MCB) unit, where...
Abstract To date, few studies on the potential utilization of agricultural residue torrefaction products have been performed. Thus, product characterization aimed at its was Wheat–barley straw pellets and wheat–rye chaff were used in study. The impact temperature (280–320 °C) polycyclic aromatic hydrocarbons (PAHs) content biochar noncondensable gas (noncondensables) composition investigated. time (30–75 min) condensable volatiles (condensables) their toxicity also studied. process performed...
Steady consumption of beer results in a steady output residues, i.e., brewer’s spent grain (BSG). Its valorization, using hydrothermal carbonization (HTC) seems sensible. However, significant knowledge gap regarding the variability this residue and its influence on valorization process potential use biorefineries exists. This study attempted to fill by characterization BSG conjunction with main product (beer), taking into accounts details brewing process. Moreover, different methods assess...

Abstract Utilization of sewage sludge, in a way friendly to the environment, is still subject intensive investigation. One possible solutions gasification sludge. Torrefaction and use additive can enhance this process. This study presents results raw mildly torrefied as well sludge with addition calcium carbonate. Overall, torrefaction mild conditions had little influence on composition obtained gas. The was much more visible when 5% carbonate added. caused increased average concentration...
Fast pyrolysis has been a subject of intensive research thanks to its ability produce high yields liquid products, known as oil. This is an important renewable intermediate which could be used for the subsequent production fuels and chemicals. For fossil-based materials, oil can provide circular building blocks. Furthermore, direct use in gas turbines also proven feasible. However, relatively oxygen content raw biomass detrimental effects on quality such work proposes hydrothermal...
