In this paper, microencapsulation methods are perused and classified into three categories, i.e. physical, physic-chemical, and chemical methods. It summarizes the techniques used for microencapsulation of PCMs and hence provides a useful tool for the researchers working in this area. Among all the microencapsulation methods, the most common methods described in the literature for the production of microencapsulated phase change materials (MEPCMs) are interfacial polymerization, suspension polymerization, coacervation, emulsion polymerization, and spray drying.

General Factorial Design (GFD) of experiments was applied in order to evaluate the aromatics production statistically. The influence of reaction conditions such as reaction temperature and Weight Hourly Space Velocity (WHSV) on the yields of the aromatic products was studied in the experiments. The reaction temperatures were set at 375, 400, 450 and 500 °C whereas the space velocity was selected to be either 2 or 4 hr-1. The products comprised of liquid hydrocarbon product (LHP), exhaust gases and water for both canola oil and CME. Moreover, thermal cracking of CME for the production of aromatics were conducted at temperatures of 450 and 500°C to compare the results with the corresponding catalytic route. The LHP was analyzed using Gas Chromatography (GC) to determine the BTX. Temperature, space velocity and feed type were found to be significant parameters for the production of aromatics. Comparison of CME and canola oil identified that catalytic cracking of CME leads to more aromatic production. Catalytic conversion of CME as well as canola oil yielded toluene as a major aromatic compound followed by para-meta xylenes and benzene. Thermal cracking of CME did not yield any aromatic products compared to the catalytic process.

Two methods of ultrasonic and conventional have been compared. Ultrasonic method has less reaction time almost half of the conventional method. The FAME contents of 90% have been obtained. The yields of 79.6% for ultrasonic and 78% for the conventional method have been achieved.

They are mainly produced by steam cracking of hydrocarbons from ethane to gasoil. The pyrolysis takes place in the tubular reactors, inside the firebox of the furnace, at high temperature, low pressure and a very short residence time. This is the only available industrial process exists for the production of olefins yet although there are other processes such as catalytic cracking for the production of such materials. This paper reviews the main research works done on the process in the literature in the last five decades. Three sections of the furnace and tubular reactors which are fixed inside the furnace have been described in detail. A mathematical model is presented for the simulation of the firebox and the reactor. Some of the main experimental laboratory setup systems in the world have been reviewed and parts of the results are presented and discussed. Finally, a few computer software packages for the simulation and online optimization of thermal cracking furnaces are presented.
