Patent number: 12275897Abstract: Carbon nanofiber doped alumina (Al—CNF) supported MoCo catalysts in hydrodesulfurization (HDS), and/or boron doping, e.g., up to 5 wt % of total catalyst weight, can improve catalytic efficiency. Al—CNF-supported MoCo catalysts, (Al—CNF—MoCo), can reduce the sulfur concentration in fuel, esp. liquid fuel, to below the required limit in a 6 h reaction time. Thus, Al—CNF—MoCo has a higher catalytic activity than Al—MoCo, which may be explained by higher mesoporous surface area and better dispersion of MoCo metals on the AlCNF support relative to alumina support. The BET surface area of Al—MoCo may be 75% less than Al—CNF—MoCo, e.g., 166 vs. 200 m2/g. SEM images indicate that the catalyst nanoparticles can be evenly distributed on the surface of the CNF. The surface area of the AlMoCoB 5% may be 206 m2/g, which is higher than AlMoCoB 0% and AlMoCoB 2%, and AlMoCoB 5% has the highest HDS activity, removing more than 98% sulfur and below allowed levels.Type: GrantFiled: March 15, 2024Date of Patent: April 15, 2025Assignee: King Fahd University of Petroleum and MineralsInventors: Tawfik Abdo Saleh Awadh, Saddam Ahmed Al-Hammadi

Patent number: 12277404Abstract: This disclosure represents an improved computer system and process to avoid the consequences of improper conversion of numbers and of rounding errors. This process makes the distinction between exact and inexact decimal floating-point numbers. If the result of a sequence of operation is exact, the user can trust that every decimal digit in the computed result is correct. On the other hand, if the input operands are inexact or the result cannot be computed exactly, a loss of significant digits occurs, and the user is warned of the loss. A novel representation is used for the inexact computed values. An estimate of the absolute error is also part of the representation.Type: GrantFiled: November 10, 2021Date of Patent: April 15, 2025Assignee: King Fahd University of Petroleum and MineralsInventor: Muhamed F. Mudawar
