Due to serious environmental problem and strict regulations to control pollution, researchers across the globe are putting their effort to find clean, renewable, greener and cost effective method to produce biochemical from biomass. The aim of this article was to highlight the method to extract phenolic compounds from crude pyrolysis oil using switchable hydrophilicity solvents (SHS). The pyrol...

Biomass mainly in the form of wood is the oldest form of energy used by humans. Biomass generally means a relatively dry solid of natural matter that has been specifically grown or has originated as waste or residue from handling such materials. The thermochemical conversion of biomass (pyrolysis, gasification, combustion) is one of the most promising non-nuclear forms of future energy. In the ...

This research evaluated the hydrocarbon emission characteristics during pyrolysis of four carbonaceous additives that can be used in green sand foundries. These included a highly volatile bituminous coal, anthracite, lignite and cellulose. The samples were flash pyrolyzed in a Curie-point pyrolyzer at 920 C with a heating rate of about 3000 C/sec. This simulated the fast heating conditions that...

Manure-derived biochar is the solid product resulting from pyrolysis of animal manures. It has considerable potential both to improve soil quality with high levels of nutrients and to reduce contaminants in water and soil. However, the combustible gas produced from manure pyrolysis generally does not provide enough energy to sustain the pyrolysis process. Supplementing this process may be achie...

Polyethylene is probably the most used plastic material in daily life and its accurate analysis is of importance. In this communication the chemical structure of polyethylenes is studied in detail using conventional analytical pyrolysis (Py-GC/MS), bulk stable isotopic analysis (IRMS) and pyrolysis compound specific stable isotopic analysis (Py-CSIA) to measure stable isotope proportions (δ(13)...

Although products of pyrolysis are often cytotoxic and mutagenic, the relationship between the type of material pyrolysed and the toxicity of the resulting pyrolysis products is poorly understood. The objective of this study was to evaluate and compare the cytotoxicity and mutagenicity of several types of common pyrolysis products. The cytotoxicity and mutagenicity of these products were assess...

The evolution of zinc oxide nanostructures grown on graphene by alcohol-assisted ultrasonic spray pyrolysis was investigated. The evolution of structures is strongly depended on pyrolysis parameters, i.e., precursor molarity, precursor flow rate, precursor injection/deposition time, and substrate temperature. Field-effect scanning electron microscope analysis, energy dispersive X-ray spectrosco...

The inert and oxidative flash pyrolysis of High Density Poly-Ethylene (HDPE) is studied 6 up to 20 000 K.s, under pressure up to 3.0 MPa and at temperature ranging from 1000 K to 7 1500 K. These conditions are considered to represent those waited onboard a hybrid rocket 8 engine using HDPE as solid fuel. Recycling applications may also find some interest. The 9 pyrolysis products are quantified...

FATE OF MICROPOLLUTANTS DURING PYROLYSIS OF BIOSOLIDS Approximately 250 tons of organic micropollutants, including pharmaceuticals, antimicrobials, and hormones, are discharged to the environment during land application of wastewater biosolids. Reusing wastewater biosolids is vital to the sustainability of wastewater treatment, but current treatment processes do not remove micropollutants from ...

In order to improve pyrolysis chromatographic analysis of materials that release polar functional groups e.g. carboxylic acids, a simple and rapid methylation method based on TDUpyrolysis/GC-MS in the presence of tetramethylammonium hydroxide (TMAH) was developed. Linseed oil was selected as test material because of its high triglyceride content comprising both saturated and unsaturated fatty a...
