Liquid fuels like dimethyl-ether (DME), produced from biomass and electricity are crucial for decarbonizing the shipping industry. In this work, production of DME wheat straw through gasification is presented. It was shown how process can be optimized by using 1) two-stage instead one-stage synthesis, 2) partial oxidation gas 3) a hydrogen quench high-temperature reverse water shift reactions. ...

The accumulation of energy from non-programmable renewable sources is a crucial aspect for the transition. Using surplus electricity sources, power-to-gas plants allow to produce substitute natural gas (SNG) that can be injected in existing infrastructure large-scale and long-term storage, contributing grid decarbonisation. plant layout, method used carbon dioxide capture possible cogeneration ...

Abstract A series of four different biomass feedstock was washed and hydrothermally carbonized at temperatures 50 °C 150–270 for hours, respectively. For the first time both resulting solid liquid products were characterised evaluated in a comprehensive study. Concerning fuel properties, HTC had higher impact on quality than washing. yielded hydrochar with carbon content starting material leadi...

Pyrolysis coupled to either thermal or catalytic cracking of mattress foam waste was performed in a laboratory-scale facility consisting fixed-bed reactor joined tubular reactor. The results showed great potential for the production syngas specially at high temperatures. Particularly, fixing 800 °C reactor, CO and CH4 rich gas with remarkable amount H2 obtained. addition catalysts (dolomite, ol...

This paper presents a new optimization approach for solving the economic operation with consideration of wind, solar, micro-turbine, fuel cells, battery and load in an energy system. Mathematical models of each micro source and the system model of the microgrid economic operation are established, and the system model is solved by improved particle swarm optimization (PSO) algorithm. The best ou...

The second-generation bio aviation fuel production via Chemical Looping Gasification (CLG) of biomass combined with downstream Fischer-Tropsch (FT) synthesis is a possible way to decarbonize sector. CLG process has the advantage producing undiluted syngas without use an air-separation unit (ASU) and improved yield compared conventional gasification processes. This study based on modelling full ...

A new method for improving the efficiency of oxyfuel gasification in biomass energy with carbon capture and storage (BECCS) cycles using dioxide recycled from exhaust gases is described modelled. Thermodynamic simulations ASPEN Plus show this process can increase indicated a representative cycle by up to 10.3 % part reducing oxygen requirements reaction. Details syngas production, cold gas (CGE...

An increasing demand in the marine industry to reduce emissions led investigations into more efficient power conversion using fuels with sustainable production pathways. Solid Oxide Fuel Cells (SOFCs) are under consideration for long-range shipping, because of its high efficiency, low pollutant emissions, and fuel flexibility. SOFC systems also have great potential cater heat ships, but integra...

Abstract Pyrolysis is a pathway for hydrogen reproduction from sewage sludge. The critical problem in the indirect pyrolysis process lower heat transfer performance furnace. circulation of media controls pyrolizer (e.g., carriers (HCs) form alumina balls), which essential determining and ultimately yield. temperature HCs amount yield are low because required vessel not satisfied. This study inv...

Recently, biomass application as a renewable energy source is increasing worldwide. However, its availability differs in dependence on the location and climate, therefore, agricultural residues cow dung (CD) are being considered to supply heat and/or power installation. This paper aims at wide evaluation of CD fuel properties prospect apply form pellets direct combustion installations. Therefor...
