Coal-char gasification with steam and steam-oxygen mixtures

Thermochimica Acta, 1985
Abstract The kinetics and pore development in steam and steam/oxygen gasification of a special coal-char derived from a German bituminous hard coal have been studied in a temperature range of 1023–1213 K. The steam gasification occurs under kinetic control causing the pore volume to grow with increasing burn-off.

Design of a process for steam gasification of PVC waste

Resources, Conservation and Recycling, 2000
One possibility for recycling of PVC waste is steam gasification in a bubbling fluidized bed reactor. The main products are syngas, employable for energy recovery and HCl that can be reused for PVC production in an oxychlorination plant. In this study the technical and economical feasibility of this process is investigated based on experimental data ...

High Pressure Steam Gasification of Coal [PDF]

Science reports of the Research Institutes, Tohoku University. Ser. A, Physics, chemistry and metallurgy, 1980
application/pdfA high pressure reactor for the steam gasification of coal was constructed and tested for two Japanese coals. The gasification rate was determined as a function of temperature, steam pressure, partial pressure of hydrogen added to steam ...

Catalytic steam gasification of lignite char

Fuel, 1989
Abstract Three different catalysts (K2CO3, Na2CO3, Li2CO3) and the mixture [(Na,K)2CO3] were impregnated onto a lignite char to determine the effects of catalyst type and amount of catalyst loading (1–5 wt%) at different reaction temperatures (700–800 °C) on the rate of steam gasification in a thermobalance reactor using large sample weights of up to

Steam Gasification and Reformation of Spacecraft Wastes

SAE Technical Paper Series, 1997
<div class="htmlview paragraph">A two-stage steam gasification and reforming process was evaluated for converting wastes generated within enclosed habitable environments into synthesis gas (CO &amp; H₂) and other recyclable inorganic species, i.e. water, CO₂ and inorganic salts.

Steam Biomass Gasification - Effect of Temperature

Applied Mechanics and Materials, 2016
Gasification is one of the technologies for utilization of biomass. Gasification is a transformation process that converts solid fuels into gaseous fuels. The gaseous fuel may be subsequently applied in other technologies with all the benefits that gaseous fuels provide. The principle of biomass gasification is a common knowledge.

Lignite Gasification in Thermal Steam Plasma

Plasma Chemistry and Plasma Processing, 2019
Recycling of organic waste is an increasingly hot topic in recent years. This issue becomes even more interesting if such processing leads to a source of hydrogen or syngas for fuel production. A process of high-temperature decomposition of lignite was studied on the plasma gasification reactor PLASGAS, where water-stabilized plasma torch was used as a

The poisoning of a steam hydrocarbon gasification catalyst

Journal of Catalysis, 1972
Abstract The factors which affect the loss of activity of a nickel alumina catalyst for the gasification of sulfur-free light hydrocarbons with steam at temperatures below 500 °C have been examined. These are sintering or loss of active surface area due to heat treatment in steam, and poisoning of active sites by a much slower parallel reaction to ...

Gasification of peat in a steam plasma reactor

The Canadian Journal of Chemical Engineering, 1985
AbstractThe gasification of finely‐divided peat (30‐micron and 48‐micron sizes respectively, and 11.4% moisture) was studied in a reactor 30.5‐cm ID and 178‐cm high, in the presence of a plasma flame consisting of nitrogen and steam, at an initial temperature of 4000 K, decreasing to 1200 K in the reaction zone.
