Investigating pyrolysis characteristics of Shengdong coal through Py-GC/MS

چکیده
Abstract Shengdong coal was single-step and multi-step pyrolyzed by pyrolysis-gas chromatography/mass spectrometry. In the pyrolysis process, Mono-ring aromatics contents reach a maximum value at 800°C, while phenolic are significantly reduced, which might be attributed to dehydroxylation of phenolics. Naphthalene content also reaches 800°C in process; however, naphthalene not detected process. So come from ring-opening multi-ring or cyclization mono-ring Only phenol o -cresol were detected, but no p meanwhile, decreased disappeared suggests that may derived isomerization alkylation phenol. It provides an idea for strengthening more basic research related rapid coal.

Progress in Coal Pyrolysis Research
The factors considered are summarized in Table 1. The problem of answering the questions is that multiple chemical reactions occur whose results depend on how the reactants are bound in the coal macromolecular network. Species-selective transport of the reactants and products further complicate the interpretations. In what follows, we have tried to focus on topics where answers are needed or wh...
متن کاملOrganic emissions from coal pyrolysis: mutagenic effects.
Four different types of coal have been pyrolyzed in a laminar flow, drop tube furnace in order to establish a relationship between polycyclic aromatic compound (PAC) evolution and mutagenicity. Temperatures of 900K to 1700K and particle residence times up to 0.3 sec were chosen to best simulate conditions of rapid rate pyrolysis in pulverized (44-53 microns) coal combustion. The specific mutage...
متن کاملFormation characteristics of aerosol particles from pulverized coal pyrolysis in high-temperature environments.
The formation characteristics of aerosol particles from pulverized coal pyrolysis in high temperatures are studied experimentally. By conducting a drop-tube furnace, fuel pyrolysis processes in industrial furnaces are simulated in which three different reaction temperatures of 1000, 1200, and 1400 degrees C are considered. Experimental observations indicate that when the reaction temperature is...
متن کاملCharacterization of the Products Obtained in Coal Pyrolysis: A Case study of Some Pakistani Coals
Thermal decomposition of two coal samples obtained from Top Seam Sibi (TSS) and Sore Range Quetta (SRQ) coal fields in their raw and acid washed forms were carried out in an open type tubular pyrolyzer coupled to a gas chromatograph with FID. Elemental analyses were carried out with Scanning Electron Microscope-Energy Dispersive X-rays (SEM-EDX) analyzer. Effect of inherent mineral contents...
متن کاملAdvanced Oxidation to Reduce Emissions in Foundries from Coal Pyrolysis
Foundries employ green sand molds, which contain coal, silica sand, clay, water, and core binders. This represents one of the largest non-combustion users of coal. When the coal experiences high temperature during the metal casting process, it undergoes pyrolysis reactions and can generate significant amounts of volatile organic compounds. Some of the compounds are released as hazardous air pol...
