Abstract:
A process is disclosed using a dispersion of supercritical fluid and oil to upgrade a hydrocarbon feedstock such as a heavy oil into an upgraded hydrocarbon product or synthetic crude with highly desirable properties such as low sulfur content, low metals content, lower density (higher API), lower viscosity, lower residuum content, etc. The process utilizes a capillary mixer to form the dispersion. The process does not require external supply of hydrogen nor does it use externally supplied catalysts.
Abstract:
Disclosed is a process for pretreatment of hydrocarbon feed containing sulfur and nitrogen compounds and aromatics prior to hydrocracking or fluid catalytic cracking which comprises:contacting said feedstock with a sulfided catalyst comprising a metal of non-noble Group VIII and Group VIB, and, optionally one or more elements selected from Group IIIA and Group VA of the Periodic Table on a carbon support consisting essentially of activated carbon, optionally on a carbon support treated with phosphorus, having a B.E.T. (Braunauer-Emmett Teller) surface area of at least 100 m.sup.2 /g and an average Pore Diameter greater than 12.ANG. and a Total Pore Volume greater than 0.3 cc/g.
Abstract:
A method for forming a wiring pattern by laser irradiation includes the steps of coating a light-sensitive material on a substrate to form a light-sensitive layer, irradiating a laser beam on the light-sensitive material of the substrate to form a pattern including an exposed region exposed to laser irradiation and an unexposed region unexposed to laser irradiation, and forming a metallic wiring pattern by immersing the substrate into a solution having a plurality of metallic nano-particles. The metallic nano-particles are easily bonded to the straighter molecular structure of the light-sensitive material in the exposed region for forming a conducting wiring pattern. The laser irradiation method has advantages such as high-power, high-density, high-directionality and monochromaticity, such that product quality can be effectively controlled. Moreover, the laser irradiated light-sensitive material can form a molecular structure that is easily bonded to the metallic particles. As a result, the chemical wastes are substantially reduced.
