Miscanthus coal gasifier

Coal gasification is a thermo-chemical process in which heat and pressure break down coal into its basic chemical constituents. The resulting “syngas” is comprised primarily of carbon monoxide and hydrogen, and occasionally other gaseous compounds. Syngas can be used for electricity production, used in energy-efficient fuel cell technology

Smolinski et al. [23] performed investigation on steam co-gasification of coal with two different biomass, e.g., Miscanthus Giganteus or Virginia Mallow (lat. Sida Hermaphrodita). Their investigation showed that the co-gasification of coal and Virginia Mallow was more effective and the synergy effects were more explicit in comparison to co

ification of coal and Sida Hermaphrodita biomass blends than for coal and Miscanthus Giganteus biomass. Further-more, more significant synergy effects in co-gasification of coal and Sida Hermaphrodita biomass were observed at lower temperature. A further, in-depth analysis of the relationships between the physical and chemical param-

Our coal gasification technology can be tailored to meet different needs, including: • Providing an alternative feedstock for chemical manufacture • Producing synthetic liquid fuels and lubricants • Generating power with lower emissions than from burning coal or even natural gas, with the option of high-pressure carbon capture and storage.

Apr 08, 2019 · Deploying coal-bioenergy gasification systems with carbon capture and storage (CBECCS) provides a promising opportunity for China to realize its carbon mitigation and air pollution abatement goals simultaneously. We conducted a comprehensive Realizing the goal of the Paris Agreement to limit global warming to 2 °C by the end of this century will most likely require deployment of carbon ...

Aug 01, 2017 · The aim of this paper is to ashaiqis the syngas production from miscanthus gasification using a numerical method. For this propose, a two-dimensional mathematical model developed and validated in an earlier work based on an Eulerian-Eulerian approach and capable to simulate fluidized-bed gasification in the fluent environment is used. To the best of the authors’ knowledge, the employment of such a high level of CFD has not been reported before for miscanthus.

Jan 17, 2007 · In the Ukraine, Miscanthus is being planted on a 5000 ha energy park, but little other information is currently available. Back in the UK, the DTI and the Carbon Trust have forecast that energy crops could supply 5%-6% of electricity demand by 2020, through a combination of combustion and gasification technologies.

Jan 01, 1999 · For miscanthus values of circa 70 % are observed in the lower h range. This is comparable to results for peat gasification at fecboard temperatures in the range of 800 - 900 (Kurkela and StBhlberg,1992 a and b and Leppalahti, 1994). For coal (exp. CSl-3) values of about 50-60 % conversion to NH3 are observed.

The Miscanthus X giganteus (MXG) presents many advantages (high yield, perennial crop, easy harvesting) so it can be considered as a good candidate in terms of renewable energy sources. Several works have been carried out and were devoted to the

As one of the most potential energy crops, Miscanthushas also been applied to all links of bioenergy development and utilization. Used as solid biofuel Coal for traditional energy supply is non-renewable in a short time, and the waste gas from coal combustion seriously pollutes the environment.

haiqi Gasifier (source: haiqi) Operation. haiqi's coal gasification technology uhaiqi a dry-feed, pressurized, entrained-flow, slagging gasifier that operates on a wide variety of feedstocks. Dried, pulverized coal is fed to the gasifier through pressurized lock hoppers using a transport gas (syngas or nitrogen).

Gasification of Miscanthus x giganteus (MxG) was conducted in an air-blown bubbling fluidized bed (haiqi) gasifier using magnesite as bed mahaiqial and a moderate rate of biomass throughput (246.82–155.77 kg/m2h). The effect of equivalence ratio (ER) (0.234–0.372) and bed temperature (645–726 °C) on the performance of gasification was investigated. The results reveal that MxG is a

The goal of this work is to understand the gasification process for Miscanthus briquettes in a double-stage downdraft gasifier, and the impact of different Equivalence Ratios (ER) on syngas, biochar, and tar charachaiqistics. The optimal ER was found to be 0.35, which yielded a syngas maximum heating value of 5.5 MJ/Nm3 with a syngas composition of 20.29% CO, 18.68% H2, and 0.86% CH4. To better
