Supercritical water gasification of ethanol fermentation residue of seaweed: effect of sodium chloride salt
The effects of sodium chloride salt on the supercritical water gasification of ethanol fermentation residue of seaweed with and without the presence of catalyst (activated carbon) were investigated. The presence of activated carbon did not affect the carbon gasification efficiency. By increasing the salt concentration, the carbon gasification efficiency is reduced until one point, the carbon ...

Impact of alkaline oxide on coal ash fusion temperature
Ash fusion temperature (AFT) is an important index for coal gasification. A blend of fluxing agent with coal can decrease the AFT to meet the requirements of specific gasification process. Effect of alkaline oxide and silica alumina ratio on decreasing AFT is focused in this study. Simulation ash was used to investigate the effect of alkaline oxide on AFT. The experimental results showed that ...

Pilot-scale demonstration of Oxy-SER steam gasification: production of syngas with pre-combustion CO₂ capture
Abstract The SER gasification process is an allothermal DFB steam gasification process in which the necessary heat for the endothermic gasification is provided by circulating bed material. Due to the low gasification temperatures of 660°C and the use of limestone as bed material, in-situ CO2 capture is possible, leading to a hydrogen-rich, carbon-lean and nitrogen-free syngas. When ...

City of Iqaluit to Test MAGS Technology
aluit will be the site for a new waste management pilot project in Nunavut, testing a micro auto gasification system or MAGS. The system will thermally decompose solid waste and oils, reducing the garbage to eight per cent of its original volume. The process creates thermal energy that will be used to heat nearby buildings, and gas that will be the main source of fuel for the system. It can ...

Techno-economic modelling of integrated advanced power cycles
Concerns regarding the environmental impacts of power generation have stimulated interest in energy efficient cycles such as the integrated gasification combined cycle (IGCC) and the integrated gasification humid air turbine (IGHAT) cycle. These advanced power cycles are complex owing to the large number of units involved, interactions among the units, and the presence of streams of diverse ...

Extraction of fuel from municipality solid wastes using an updraft gasifier
In Bangladesh, cities are confronted with the problem of how to dispose large quantities of municipal solid waste (MSW). Gasification is a process that uses heat, pressure and steam to convert materials (MSW) directly into a gas composed primarily of carbon monoxide and hydrogen. The main objectives of this paper are: 1) to study gasification processes; 2) to design, fabrication and performance ...

The MAGnificent Seven - Gunning for Marine Waste
Waste Management World focused this article on Terragon Environmental Technologie's product, MAGS (Micro Auto Gasification System) and the solution it provides to the maritime sector. MAGS transforms solid waste and sludges into energy which can be intergrated at the site where waste is generated. New regulations from MARPOL Annex V came into effect on January 1, 2013 - virtually banning the ...

Preparation of mesoporous activated carbon from palm-date pits: optimization study on removal of bentazon, carbofuran, and 2,4-D using response surface methodology
Palm-date pits were used to prepare activated carbon by physiochemical activation method, which consisted of potassium hydroxide (KOH) treatment and carbon dioxide (CO2) gasification. The effects of variable parameters, activation temperature, activation time and chemical impregnation ratios (KOH: char by weight) on the preparation of activated carbon and for removal of pesticides: bentazon, ...

Carbon capture and storage (CCS) technologies and economic investment opportunities in the UK
This article reviews the role played by carbon and capture (CCS) technologies in order to facilitate the transition to low-carbon emitting technologies in the medium-term. More precisely, we address the following central questions: how will the development of CCS technologies impact energy policies in order to yield to sustainable energy solutions? At what costs will pollution reductions be ...

Sewage Sludge Treatment
Many wastewater treatment plants are coping with a waste stream of digested sludge. The sludge is normally dewatered by means of a centrifuge or belt filter press. After dewatering the sludge has a typical dry solids content of approx. 20 - 25%. Every country has a lot of problem with the fast increasing sludge, shortage of sewage treatment plant and limitation of landfill size. The volume is ...

Automobile Shredder Residue (ASR) destruction in a plasma gasification reactor
Test results on Automobile Shredder Residue (ASR), or car fluff, demonstrated destruction efficiency and safe conversion to synthesis gas and a glass residue, in a plasma gasification system. The synthesis gas consists primarily of hydrogen and carbon monoxide in the range between 20 and 22 vol-% respectively, or 45 and 55 vol-% dry basis, when corrected for nitrogen. In dry reforming operation, ...

Biodegradability of some nitrogenous heterocyclic compounds and co-degradation with phenol by denitrifiers in anoxic sludge reactor
Phenol and nitrogenous heterocyclic compounds (NHCs) are typical organic pollutants in coal gasification wastewater which are difficult to deal with. Unlike phenol, the stable molecular structure of NHCs make them nearly impossible to degrade under aerobic or anaerobic condition. In this paper, biodegradation of phenol and NHCs as carbon sources for denitrification was studied in a ...
