Bio-oil produced from fast pyrolysis of biomass has been investigated as a renewable fuel and as a source of industrial chemicals. The lignin fraction of bio-oil produced from wood in our fast pyrolysis reactor was separated by using only water and methanol with a 25% yield based on bio-oil weight. This separation procedure appears to be of lower cost than the reported extraction procedure usin...

the major sources of pahs are anthropogenic. these may be generated by pyrolytic and petrogenic processes. low molecular weight pahs come into the aquatic system through the accidentally leakage of oil spills. incomplete combustion at high temperature will release high molecular weight pahs by products of pyrolytic processes. the methods for assigning sources of pahs include paired isomeric rat...

Worldwide energy crisis forced the researchers to explore for new and alternate sources of energy. For the developing countries this problems are acute. Generation of any kind of waste is a problem to the environment. Some wastes have the characteristics of producing energy by different thermochemical conversion. In the present work, waste tires were pyrolysed in a fixed bed reactor. The influe...

CCA has been banned for residential use as a wood preservative in North America by the end of 2003. The alternatives will be copper-based chemicals, such as Ammonium Copper Quat (ACQ) or Copper Azole (CA). Leaching of copper from treated wood to environment will become one of the most important issues for the wood preserving industry. So far, no wood treatment with the new copper alternatives o...

This paper aims to study decomposition behavior in pyrolytic environment of four lignocellulosic biomass (oil palm shell, oil palm frond, rice husk and paddy straw), and two commercial components of biomass (pure cellulose and lignin), performed in a thermogravimetry analyzer (TGA). The unit which consists of a microbalance and a furnace flowed with 100 cc (STP) min Nitrogen, N2 as inert. Heati...

Surface sediments collected from 33 stations along the Ambarli Harbor, the Sea of Marmara, were analyzed for petroleum aromatic hydrocarbons by UV-fluorescence. Higher concentrations of total aromatic hydrocarbons were found of all the samples collected during May 2009, with levels ranging 1860 and 72 μg/g eq oil (205 and 7 μg/g chrysene eq.). The spectra indicate dominant pyrolytic origins in ...

Granules of waste tires were pyrolyzed under vacuum (3.5-10 kPa) conditions, and the effects of temperature and basic additives (Na2CO3, NaOH) on the properties of pyrolysis were thoroughly investigated. It was obvious that with or without basic additives, pyrolysis oil yield increased gradually to a maximum and subsequently decreased with a temperature increase from 450 degrees C to 600 degree...

A fixed bed pyrolysis has been designed and fabricated for obtaining liquid fuel from mustard de-oiled cake. Thermal pyrolysis of mustard deoiled cake were carried out in a semi batch reactor made up of stainless steel at temperature range from 450 0 C to 600 0 C and at a rate of 150C /min to produce bio-fuel. The maximum yield of oil was 51% on wt. % basis for mustard de-oiled cake, it was obt...

This paper reports the pyrolytic treatment of granulated scrap tires (GST) in a pilot distillation unit at moderate temperature (550°C) and atmospheric pressure, to produce oil, char and gas products. Tire-derived oil is a complex mixture of organic C(5)-C(24) compounds, including a very large proportion of aromatic compounds. This oil has a high gross calorific value (∼ 43 MJ kg(-1)) and N and...
