Oil sludge, if unused, is one of the major industrial wastes that needs to be treated for the refinery or petrochemical industry. It contains a large portion of combustible components with high heating values. Obviously, the conversion of oil sludge to various useful materials such as lower molecular weight organic compounds and carbonaceous residue via pyrolysis not only solves the disposal
Pyrolysis is frequently associated with thermal treatment. But in contrary to combustion and gasifications processes, which involve entire or partial oxidation of material, pyrolysis bases on heating in the absence of air. This makes it mostly endothermic process that ensure high energy content in the products received.
Pyrolysis oil, sometimes also known as biocrude or biooil, is a synthetic fuel under investigation as substitute for is obtained by heating dried biomass without oxygen in a reactor at a temperature of about 500 #176;C with subsequent cooling. Pyrolysis oil is a kind of tar and normally contains levels of oxygen too high to be considered a pure hydrocarbon.
Pyrolysis process. In the pyrolysis, it was used a Macro ATG oven (), developed by the Center for International Cooperation in Agronomic Research for Development CIRAD (France) in partnership with the Federal University of Lavras UFLA (Brazil).This equipment is a prototype of a vertical electric oven with a pyrolysis reactor and load cell connected to a pyroligneous liquid condenser.
The whole process can be summarized into three main steps: The formation of turbulent gaseous stream by intermixing the carrier gas, the solid biomass and the hot char using a designed mixing zone, passing the gaseous steam into the pyrolysis chamber and allowing to go through pyrolysis at temperature of about 800#176;C for about 10 s, and finally removing the pyrolyzed gaseous stream from the
Pyrolysis, the chemical decomposition of organic (carbon based) materials through the application of heat. Pyrolysis, which is also the first step in gasification and combustion, occurs in the absence or near absence of oxygen, and it is thus distinct from combustion (burning), which can take place only if sufficient oxygen is present.
Carbon Coke Chemical Analysis The following refers to the process of thermolysis of organic fractions of municipal solid waste in a pilot scale reactor. The results are compared with others obtained under laboratory conditions (semipilot scale):

The rate of pyrolysis increases with temperature.
#0183;#32;Biomass pyrolysis is the thermal decomposition of biomass occurring in the absence of oxygen. It is the fundamental chemical reaction that is the precursor of both the combustion and gasification processes and occurs naturally in the first two seconds.

Simulated pyrolysis results suggested that the heatnotburn condition, which has a much lower pyrolysis temperature than THS, may cause distinct shifts in the composition of the smoke compared to 3R4F. Some of the chemical constituents (eg, carbonyls and ammonia) from THS and 3R4F varied under the two smoking regimes.
The chemical industry makes extensive use of the process of pyrolysis. One of the most important applications of this process is in the production of ethylene and other important carbon compounds from coal and petroleum. Furthermore, it can be noted that these compounds can also be extracted from certain organic matter such as wood.

Pyrolysis is the fundamental chemical reaction process and is simply defined as the chemical change that occurs when heat is applied to a material in the absence of oxygen. Hydrothermal upgradation (HTU) is one of the processes of a general term of thermochemical conversion (TCC), which includes gasification, liquefaction, and pyrolysis.
Pyrolysis involves the chemical transformation (decomposition) of a sample on heating to a high temperature ( #176;C).72 When combined with GC, the technique involves a pyrolyzer into which samples to be analyzed are loaded. Target analytes are typically very high molecular weight compounds.
