Shell Waste

Coconut shell waste is a waste that has a high carbon content. Carbon in coconut shell waste can be converted into activated carbon having a large surface area. This potential property is suitable to apply the coconut shell as catalyst support. To increase the catalytic activity, metal oxides such as Cr2O3 are impregnated. The purpose of this study is to synthesize Cr2O3/carbon catalyst and test its catalytic activity on catalytic cracking of Jatropha oil. The first stage was the synthesis of activated carbon and the determination of its proximate and ultimate. The second step was impregnation to produce Cr2O3/carbon catalyst. Furthermore, X-Ray Diffraction to determine crystallinity, Surface Area Analyzer to identify its surface area and Fourier Transform Infrared to analyze functional groups. Then the catalytic activity was tested on the catalytic cracking of Jatropha oil. In addition, the chemical compound composition and biofuel selectivity of the catalytic cracking product was determined using Gas Chromatography-Mass Spectrometer. Proximate analysis results showed that activated carbon contains 9%, 1%, 23%, and 67% of water, ash, evaporated substances, and bound carbon, respectively. The results of the ultimate analysis resulted in carbon (C), hydrogen (H), and nitrogen (N) contents of 65.422%, 3.384%, and 0.465%, correspondingly. The catalyst crystallinity test showed the presence of Cr2O3 peaks at 2θ: 24.43°; 33.47° and 36.25° according to JCPDS No. 84-1616. In the absorption area of 400-1000 cm-1 and the range of 2000 cm-1 showed the presence of Cr-O stretching due to Cr2O3 adsorbed into the activated carbon structure. The surface area of activated carbon and Cr2O3/carbon catalysts with a concentration of 1.3, and 5% was 8.930 m2/g; 47.205 m2/g; 50.562 m2/g; and 38.931 m2/g, respectively. The catalytic activity test presented that the best performance was showed by Cr2O3/carbon catalyst with a concentration of 5% indicated by conversion of Jatropha oil into biofuel of 67.777% with gasoline selectivity, kerosene, and diesel of 36.97%, 14.87%, and 15.94%, correspondingly.

High Spatial Resolution Imaging

We have used high spatial resolution imaging secondary ion mass spectrometry (SIMS) to differentiate mineralogical phases and to investigate chemical segregations in fluidized catalytic cracking (FCC) catalyst particles. The oil industry relies on heterogeneous catalysis using these catalysts to convert heavy hydrocarbon fractions into high quality gasoline and fuel oil components. Catalyst performance is strongly influenced by catalyst microstructure and composition, with different chemical reactions occurring at specific types of sites within the particle. The zeolitic portions of the particle, where the majority of the oil conversion occurs, can be clearly distinguished from the surrounding silica-alumina matrix in analytical SIMS images.The University of Chicago scanning ion microprobe (SIM) employed in this study has been described previously. For these analyses, the instrument was operated with a 40 keV, 10 pA Ga+ primary ion probe focused to a 30 nm FWHM spot. Elemental SIMS maps were obtained from 10×10 μm2 areas in times not exceeding 524s.

High Regeneration

The spatial distribution of V and Ni deposited within fluidized catalytic cracking (FCC) catalyst is studied because these metals contribute to catalyst deactivation. Y zeolite in FCC microspheres are high SiO2 aluminosilicates with molecular-sized channels that contain a mixture of lanthanoids. They must withstand high regeneration temperatures and retain acid sites needed for cracking of hydrocarbons, a process essential for efficient gasoline production. Zeolite in combination with V to form vanadates, or less diffusion in the channels due to coke formation, may deactivate catalyst. Other factors such as metal "skins", microsphere sintering, and attrition may also be involved. SEM of FCC fracture surfaces, AEM of Y zeolite, and electron microscopy of this work are developed to better understand and minimize catalyst deactivation.
