  • Patent number: 11493273
    Abstract: A method for measuring the softening and melting performances of iron ore in blast furnace is disclosed, which is implemented by a device including a high temperature furnace, gas supply system, a loading system and a weighing system. The method includes: step 1: the dried coke and iron ore specimen are placed in the graphite crucible in a specified way; step 2: the graphite crucible is placed in the high temperature furnace, and N2 is continuously fed into the high temperature furnace to reach an airtightness requirement; step 3: a vacuum pump is used to extract mixed gas in a hearth of the high temperature furnace and heating process is started; step 4: both the composition of mixed gas and pressure imposed on the iron ore are controlled according to the designed temperature variation; step 5: data are acquired to calculate.

  • Patent number: 11111446
    Abstract: A temperature-controlling measure for a hydrogenation slurry bed reactor has three control points that are set from low to high: cold hydrogen is injected automatically when the system reaches control point 1; cold oil in injected automatically when the system reaches control point 2; each pressure relief is opened automatically when the system reaches control point 3. The pressure relief point is set before and/or after the circulation pump of the reactor if internal circulation is set in the reactor; the pressure relief point is set at the reactor bottom if the internal circulation is not set; at least one pressure relief valve is set at each pressure relief point.

  • Publication number: 20170145320
    Abstract: A residue slurry bed hydrocracking method and device is used in the deep processing of crude oil. The processes of “slurry bed+fixed bed” reactor are applied. Raw materials, additives, catalysts and hydrogen are mixed, heated and pressurized before they are introduced into the slurry reactor, where thermal cracking and catalytic reactions occur under high hydrogen partial pressure. The coke, catalysts and additives in the reaction process are separated at the bottom of the heated high pressure separator (HHPS). Then they are transferred in a conventional fixed bed reactor to do further hydrocracking and hydrorefining, to product light oil products. The new Mo-Fe based catalyst developed in the invention can improve the activity of the main reactions, inhibit the reaction of coke production, and reduce system pressure from 20 Mpa to 17 Mpa, which can reduce device costs. Conversion rates can reach 90-95%, with the yield of light oil reaching 80-83%.
