The products obtained from thermal cracking of plastics depend on the type of plastics, feeding arrangement, residence time, temperatures employed, reactor type, and condensation arrangement [42]. Reaction temperature and residence time have strong influence on the yield of pyrolysis products and the distribution of their components for plastic samples. Jude et al. conducted smdies on thermal cracking of LDPE in a batch reactor resulted in the production of a broad range of hydrocarbon compounds where the yield of aromatics and aliphatics (olefins and paraffins) deeply depended on the pyrolysis temperature and residence time. 

Any chemical compound of hydrogen and carbon also called an organic compound. Hydrogen and carbon atoms can be combined in virtually countless ways to make a diversity of products. Carbon atoms form the skeleton of the hydrocarbon molecule, and may be arranged in chains (aliphatic) or rings (cyclic). There are three principal types of hydrocarbons that occur naturally in petroleum parajfins, naphthenes, and aromatics, each with distinctive properties. Paraffins are aliphatic, the others cyclic. Paraffins and naphthenes are... 

If now, the long chain molecules are oriented parallel to a crystal lattice, the two groupings shown in Fig. 40 are possible. Simple hydrocarbons of regular shape are known to prefer arrangement 1 and consequently form laminae preferably. The paraffins, naphthalene and anthracene are especially good representatives of this type. If type 2 is assumed, the conditions are less clear the products crystallize, as a rule, in needles (diphenyl, dibenzyl, etc.).
