Catalytic cracking of the pyrolysis oil was conducted using an HZSM-5 catalyst in a dual reactor. The effects of reaction temperature, catalyst weight, and nitrogen flow rate were investigated to determine the yield of organic liquid product (OLP) and the percentage of gasoline aromatics in the OLP. More loosely, outside the field of petroleum chemistry, the term "cracking" is used to describe any type of splitting of molecules under the influence of heat, catalysts and solvents, such as in processes of destructive distillation or pyrolysis. Fluid catalytic cracking produces a high yield of petrol and LPG, while hydrocracking is a major source of jet fuel, Diesel fuel, naphtha, and again yields LPG. The equilibrium FCC catalyst is able to crack oxygenates presents in pyrolysis oil such as acetic acid and guaiacol. Further the crackability pattern of pyrolysis oxygenates supported by the vibrations of C O and O H absorption peaks (of FTIR) and NMR data of liquid product. Cracking is the result of a pyrolysis treatment to hydrocarbon feedstock, the breaking of long hydrocarbon molecules into smaller ones. Another term you often find is “destructive distillation”, which is one variant of pyrolysis typically used for the decomposition of coal into coal gas, coal oil, coal tar and coke.

It is very much essential to upgrade pyrolysis oil further either by hydrodeoxygenation or zeolite cracking (fluid catalytic cracking) route.

Alexander Reichhold. The crude fast pyrolysis oil from Jatropha curcas is produced at 530 °C and atmospheric pressure using a bubbling fluidized bed pyrolyzer. The heavy fraction of waste lubricant oil are cracking and pyrolysis. The cracking process yields a highly unstable low-grade fuel oil, which can be acid-corrosive, tarry, and discolored

bons can further undergo secondary cracking reactions, yielding ethene, propene and other products. The reaction mechanism of heavy oil catalytic pyrolysis is

The catalytic cracking of rapeseed oil (RSO) or canola oil, which is a form of RSO having low levels of erucic acid in its oil and low levels of glucosinolates in its meal, has been investigated extensively. A part of heavy oil (boiling point >773 K) was cracked to increase the yields of light oil and pyrolysis gas (especially H2 and CH4). The shale ash bed temperature was the key factor affecting the product distribution. The catalytic effect of shale ash lowered the shale oil cracking temperature for achieving the same degree of oil cracking. Pyrolysis is a two-phase treatment which uses thermal decomposition to heat the rubber in the absence of oxygen to break it into its constituent parts, e.g., pyrolysis oil (or bio oil), synthetic gas and char. Cracking and post-cracking take place progressively as the material is heated to 450-500°C and above.

Keywords: n-octadecane, pyrolysis experiment, gaseous hydrocarbon, stable carbon isotope, kinetic lution of oils is controlled by the kinetics of cracking re-. Wang et al. [9] developed a 16-lump model for the heavy oil contact cracking ( HCC) process. This model divided the pyrolysis gas into eight lumps (hydrogen, fraction and fuel oil. Naphtha. Pyrolysis Furnace. Transfer Line Exchange. ( producing steam). Cracked gas. Oil/water quench tower and oil fractionator. Three products are usually produced: gas, pyrolysis oil and charcoal, the relative The gasification pushes to the maximum level the cracking of biomass by Pyrolysis is also known as thermal cracking, cracking, thermolysis, depolymerization, etc. At any given temperature the molecule is in vibrating stage . This is called of the carbon in pyrolysis oil). The upgraded oils were subsequently tested in a lab scale catalytic cracking unit (MAT reactor), assessing the suitability of HDO 12 Mar 2014 Mainly water soluble monomers. • Ignored by many researchers because of large amount of water in light oil (~40-80w/w%). • Yield of light oil
