Publication number: 20100224535Abstract: A supported carbon having high surface area, high pore volume containing (i) molybdenum (ii) a metal of non noble Group VIII, (iii) phosphorous, is used for hydrometallization of heavy crude oil and residue. The catalyst contains about 6 to 15 wt % molybdenum as MoO3, about 1 to 6 wt % cobalt or nickel as CoO or NiO and phosphorus as phosphorous oxide. One characteristic of the catalyst is the portion of pores having pore diameter in the range of 200 to 2000 Angstrom of 20 percent or more. The catalyst prepared by chelating agent has higher hydrodesulfurization activity assuming that more dispersed active metals are present on this catalyst. Long run activity studies show that catalyst having only molybdenum supported on activated carbon has good stability with time-on-stream and very high metal retention capacity.Type: ApplicationFiled: March 3, 2010Publication date: September 9, 2010Applicants: INSTITUTO MEXICANO DEL PETROLEO, TOYO ENGINEERING CORPORATIONInventors: Samir Kumar Maity, Jorge Ancheyta Juárez, Fernando Alonso Martínez, Hidetsugu Fukuyama, Satoshi Terai, Masayuki Uchida

Patent number: 7496450Abstract: The invention relates to an image-reconstruction technique which is used to view multiphase flows using electrical capacitance tomography (ECT), which is based on non-linear heuristic global optimization methods involving simulated annealing and genetic algorithms. The inventive method consists in obtaining electrical capacitance data which are measured between electrodes positioned on the outer surface of pipeline, well or tank (electrically-insulating) containing fluids. The aforementioned data are dependent on the distribution of the fluids inside the pipeline, well or tank. Moreover, the data are processed in order to reconstruct an image of the spatial distribution of the relative electrical permittivity (also known as the dielectric constant) inside the tube, well or tank, which reflects the distribution of the different phases present in the flow.Type: GrantFiled: August 22, 2003Date of Patent: February 24, 2009Assignee: Instituto Mexicano del PetroleoInventors: José Carlos Ortiz Alemán, Roland Martin, José Carlos Gamio Roffé
