The primary oil processing product is a mixture of different hydrocarbons. One of the hard-to-process petroleum products is fuel oil. This paper considers a method to derive clear (light) fractions of petroleum products by the catalytic processing of fuel oil on a zeolite-containing catalyst at 1 atm under the technological conditions of aerosol nanocatalysis. The prospect of the catalytic processing of a viscous residue ‒ fuel oil ‒ has been analyzed and estimated. The process is carried out by dispersing the catalytically active component in a vibratory-fluidized layer. Chemical transformation occurs during the constant mechanochemical activation of catalyst particles by forming an aerosol cloud in the reactive volume. Natural zeolite catalyst of the type Y was selected for research. Methods for separating the gasoline and diesel fractions of light hydrocarbons and for analyzing the gas phase have been given. The effect of the concentration of zeolite catalyst aerosol on the composition of cracking products (the yield of the gasoline and diesel fractions of light hydrocarbons) has been studied. It is noted that the rate of the course of fuel oil processing in the aerosol of the catalyst is 1.5‒2 times higher than that in thermal processing. It has been found that in fuel oil processing based on the aerosol nanocatalysis technology, the concentration of the catalyst can be controlled to produce the final product. The study results have shown that the optimal conditions for processing fuel oil in the aerosol of the catalyst should be considered 773 K, a frequency of 5 Hz, a pressure of 1 atm. At the same time, a concentration of the catalyst of 1‒5 g/m3 should be considered optimal for the output of a light fraction of hydrocarbons. In this case, the yield is up to 80 % of the fraction in the laboratory. It was found out that during the processing of fuel oil, the concentration of the catalyst makes it possible to optimize the output of light oil products under the technological conditions of aerosol nanocatalysis

Palm oil is one of the crops that produce crude palm oil (CPO). Losses or loss of production is generally a natural thing in the palm oil processing process. Oil losses are the loss of the amount of oil that should be obtained from the results of a process but the oil cannot be obtained or is lost. The loss rate for palm oil is the amount of oil that is not taken up in the processing. The oil that is not taken is partly wasted into the boiler as fuel (oil from fiber). Oil losses are the loss of the amount of oil that should be obtained from the results of a process but the oil cannot be obtained or is lost. In testing oil losses using the socket extraction method. Soxlet extraction is a continuous extraction technique using a soxhlet, with the principle of distillation of solvent from the flask to the cooler, then dripping wet and immersing the sample located in the center of the soxlet apparatus.

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.

INTRODUCTION Recently, a new compound carbon nitride (CNx) has captured the attention of materials scientists, resulting from the prediction of a metastable crystal structure β-C3N4. Calculations showed that the mechanical properties of β-C3N4 are close to those of diamond. Various methods, including high pressure synthesis, ion beam deposition, chemical vapor deposition, plasma enhanced evaporation, and reactive sputtering, have been used in an attempt to make this compound. In this paper, we present the results of electron energy loss spectroscopy (EELS) analysis of composition and bonding structure of CNX films deposited by two different methods.SPECIMEN PREPARATION Specimens were prepared by arc-discharge evaporation and reactive sputtering. The apparatus for evaporation is similar to the traditional setup of vacuum arc-discharge evaporation, but working in a 0.05 torr ambient of nitrogen or ammonia. A bias was applied between the carbon source and the substrate in order to generate more ions and electrons and change their energy. During deposition, this bias causes a secondary discharge between the source and the substrate.

Utilization of conventional energy sources such as coal, fuel oil, natural gas and others on the one hand has a low operating cost, but on the other side of the barriers is the greater source of diminishing returns and, more importantly, the emergence of environmental pollution problems dangerous to human life. This study aims to formulate the kinematics and dynamics to determine the movement of Solar Power Mower. In this study, using solar power as an energy source to charge the battery which then runs the robot. Design and research was conducted in the Department of Mechanical Workshop Faculty of Engineering, University of Hasanuddin of Gowa. Control system used is a manual system using radio wave transmitter and receiver which in turn drive the robot in the direction intended.
