A gas coal (B) was used to study the effect of volatiles on sulfur removal from a high organic-sulfur coking (A) perspective mass transfer conditions. The driving force and resistance were analyzed in terms fluidity development, permeability plastic stage flow, volatile matter release. Carbonization using vertical horizontal stacking modes two coals designed according release directions during ...

• Distillate residues from biomass pyrolysis oils were synthesized into renewable pitch. The biopitch properties closely align with those of coal tar Diverse biomasses used allow greater flexibility for biorefineries. Petroleum-based carbon solid materials, such as petcoke and pitch, have decreased in quality and/or availability due to various factors, the declining elemental crude oil push tow...

In order to integrate renewable electricity into the power grid, it is crucial for coal-fired plant boilers operate stably across a wide load range. Achieving steady combustion with low nitrogen oxide (NOx) emissions poses significant challenge burning low-volatile coal in plants. This study focuses on developing decoupling technology operating at loads. A three-dimensional numerical simulation...

the purposes of this article are studying the effects of oxygen presence on waste wood pyrolysis process in order to produce bio-char. to reach the goal, cubic samples of size 2.5 cm pyrolized at 300 and 400 °c. the surface and center temperatures of samples were measured and their mass losses were calculated from the ratio of pyrolized mass to initial mass of the sample. increase in temperatur...

The co-pyrolysis of waste electrical and electronic equipments (WEEEs) and waste biomass to obtain pyrolysis-oil, a liquid fuel or chemical feedstock, was carried out in the present work. The pyrolysis-oil yield of co-pyrolysis reached 62.3% which was significantly higher than those of pyrolysis of WEEEs and biomass alone (i.e., 53.1% for WEEEs and 46.3% for biomass), suggesting that synergisti...

Thermochemical conversion via co-pyrolysis has the potential to be an efficient route for converting biomass bio-energy and bio-refinery products. In this review, implementation of torrefied coal was critically assessed against raw from both a fundamental engineering perspective. This evaluation showed advantages torrefaction prior such as decrease in mass heat transfer limitations due increase...

The characteristics of enzymatic/mild acidolysis lignin (EMAL) isolated from moso bamboo were investigated using pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). Pyrolysis temperature as a factor on products was studied, and the pyrolysis mechanism was inferred with respect to the dominating products. Research results showed that pyrolysis products derived from EMAL pyrolysis were mai...
