This chapter gives an overview of renewable hydrocarbon production through triglyceride's thermal-cracking process. The influence of feedstock characteristics and availability is discussed. It also presents issues about the reaction, the effect of operational conditions, and catalysts. A scheme of the reaction is presented and discussed. The composition and properties of bio-oil is presented for both thermal and catalytic cracking. The high content of olefins and the high acid index are drawbacks that require downstream processes. The reactor design, kinetics, and scale-up are opportunities for future studies. However, the similarity of bio-oil with oil turns this process attractive.

The purpose of this research are to study the temperature influence in hydrocracking process of the nyamplung oil (Calophyllum inophyllum) using a non-sulfided CoMo/γ-Al2O3 catalyst and to develop a simple kinetic model in interpreting the data of hydrocracking products. The experiment was carried out in a pressurized batch reactor operated pressure up 30 bar. The CoMo catalyst supported with γ-Al2O3 was prepared through impregnation method without sulfidation process. The operating temperature varied from 200 to 350 o C. The results show that the non-sulfided CoMo/γ-Al2O3 catalysts, nyamplung oil triglycerides can converted into gasoil and gasoline-like hydrocarbons. The triglyceride hydrocracking reaction of nyamplung oil followed a several stages, i.e., hydrogenation, dehydrogenation, and cracking. Based on the compounds contained in liquid product, hydrocracking reaction was dominated by decarboxylation. The products obtained in hydrocracking process of nyamplung oil are classified to gasoil (C11-C18) and gasoline (C5-C10). The triglycerides hydrocracking reaction of nyamplung oil was assumed by following a series reaction mechanism and a simple kinetic model used for determined the kinetics constants. The highest reaction conversion is 99.10% obtained at temperature of 350 °C for 160 minutes reaction time.

“…At 440°C, hydrocarbon biofuel and distillation residual yield decreased to 19.81 wt.% and 48.89 wt.% which was due to severe cracking reaction. Liquid hydrocarbons and triglycerides were cracked into gaseous products 10 . Another possible reason is the formation of coke from aromatic hydrocarbons through polymerization and aromatization that result in high coke yield 8 .…”

To produce high yield and quality hydrocarbon biofuel, HZSM-5 zeolite loaded with different Zn concentrations (5, 10, 15 and 20wt.%) was used to palm oil cracking in batch reactor. Reaction temperature and reaction time were optimized. The products contained liquid hydrocarbon biofuel, distillation residual and coke. The physical properties of biofuel products were determined. The results presented that 15% Zn/HZSM-5 exhibited higher hydrocarbon biofuel yield (20.27%) and their excellent product properties with higher heating value (HHV), low viscosity and moisture content. A highest hydrocarbon biofuel yield and good alkane range hydrocarbons distribution from palm oil were obtained under reaction temperature of 420°C for 5 hours.
