In this work, the sulfur transformations during thermal conversion of two straw samples have been experimentally investigated. Sulfur was found to be associated partly as inorganic sulfate (40−50% total S) and organic (50−40%) in typical Danish wheat samples. Batch pyrolysis combustion experiments were conducted a lab-scale tubular reactor order obtain quantitative information on devolatilization char burnout. The indicated that 35−50% released gas phase devolatilization. release...
Initial reaction mechanisms of lignin pyrolysis were studied by large-scale ReaxFF molecular dynamics simulations (ReaxFF MD) facilitated the first GPU-enabled code (GMD-Reax) and unique analysis tool (VARxMD). Simulations performed over wide temperature ranges both for heat up at 300–2100 K NVT 500–2100 with a large model, which contained 15920 atoms was constructed based on Adler's softwood model. By utilizing relatively continuous observation pyrolysate evolution in slow simulations,...
Carbon dioxide sequestration in coal seams with enhanced coal-bed methane recovery (CO2-ECBM) is considered as a promising option for permanent carbon storage. As one of the most important factors to success CO2-ECBM process, adsorption and CO2 on helps assess amount recoverable well storage capacity targeted seam. In this work, isotherms were measured volumetric technique at temperatures 35, 50, 65 °C pressures up 16 12 MPa (CO2 35 limited below 6 MPa), respectively. Four coals various rank...
Biomass gasification and pyrolysis were studied in a laboratory-scale atmospheric pressure entrained flow reactor. Effects of operating parameters biomass types on the syngas composition investigated. In general, carbon conversion during was higher than 90% at optimal conditions 1400 °C with steam addition. The that not converted to gas process only appeared as soot particles all experiments, except for two experiments performed 1000 °C, where very small amount char also left. comparison...
The gas-sensitive properties of nanostructured 94, 85, 71 and 7 mol% materials prepared by high-energy ball milling have been investigated in atmospheres containing alcohol, CO gases. It has found that the show a high sensitivity with short response time to alcohol gas almost no other two gases, concentration ranges studied. Furthermore, behaviour these discussed on basis microstructure materials. is tin ion content ions surface particles may play an important role enhancement sensitivity.
The catalytic effects of five metal chlorides, including CaCl2, KCl, NiCl2, CoCl2, and ZnCl2, on the pyrolysis lignite were investigated by thermogravimetry Fourier transform infrared (TG-FTIR) analysis. results showed that CaCl2 ZnCl2 inhibited conversion organic matters into light species during samples, while CoCl2 promoted conversion. effectiveness these chlorides in samples decreased following order: > KCl NiCl2 ZnCl2. yields from can be CaCl2. effect was similar to except it increased...
A better understanding of the influence particle size on pyrolysis and char reactivity is crucial importance in optimizing integrated process combining coal topping (coal fast pyrolysis) with gasification. Different fractions two types demineralized were pyrolyzed a spouted bed. The resulting chars characterized by X-ray diffraction, was determined thermogravimetric analyzer (TGA). Within range sizes investigated, an increase results yield, which may be caused secondary reactions volatile...
Experiments were carried out in a downer reactor integrated circulating fluidized bed combustor to examine the performance of coal topping process. The effects reaction temperature and particle size on product distribution their compositions determined. experimental results show that an increase will yields gas liquid product, yield decreases with size. experiments exhibit optimal condition for product. When pyrolysis is 660 °C less than 0.28 mm, light tar (hexane-soluble fraction) reaches...
