  • Patent number: 4180543
    Abstract: In a reactor suitable for gas-phase catalytic exothermic synthesis, in particular of ammonia or methanol the synthesis gas is reacted in an upstream adiabatic catalytic zone, is cooled in a heat exchanger and then reacted further in a downstream catalytic zone, whereafter preferably it is cooled again, suitably in a boiler or feed water heater, and reacted further in a further catalytic zone. The gas flow through the catalyst is mainly in an axial direction and the pressure drop is kept low by disposing the catalyst in each zone in a plurality of beds fed in parallel from an inlet header and delivered in parallel into an outlet header. The beds may be separately removable from the reactor to facilitate catalyst charging and discharging.

  • Patent number: 4178238
    Abstract: Apparatus for use with extremely low-grade aggregate ore, for deriving a concentrate comprised of metal-bearing ore particles having densities within a predetermined range. The apparatus is in the form of a mobile, self-sustained system including a vehicle trailer for horizontal transport and elevated operational support, plus an integral power system capable of supplying the total energy requirements of the apparatus. Two types of particle size separation are applied, followed by compaction and particle density separation. Two density separation areas are provided to effect both coarse and fine gravitational shaving actions, and dual adjustment controls are also provided to vary the shaving force intensity to derive the concentrate independently of changes in the particular characteristics of the aggregate being processed. The apparatus includes outer and inner cylindrical chambers concentrically mounted on the trailer so as to be tiltable and rotatable.

  • Patent number: 4169767
    Abstract: A process for calcining green coke containing water and combustible volatile matter and obtained by a delayed coking process in three or more stages of heating furnaces which are connected in series, and the control of the temperature and the adjustment of the atmosphere in the respective furnaces can be independently carried out, which process comprises carrying out, in respective furnaces in the indicated order, the steps of:(a) evaporating the water contained in the green coke, and drying and pre-heating the coke;(b) distilling off and burning the volatile matter from the dried coke; and(c) heating and calcining the coke from the step (b).Because each furnace can be controlled independently from the other furnaces in the above described process, it is possible to produce high-grade coke without process difficulties such as the loss of the coke by combustion and the formation of coke ring.

  • Patent number: 4168208
    Abstract: An elbow cover for a coke oven ascension pipe characterized in that the opening which is covered is oval in shape and is formed at the junction of the ascension pipe and a downwardly-extending supply pipe leading to a gas-collecting main. The oval-shaped cover is provided with an immersion cup seal and a spaced sealing plate. Because of the oval shape of the opening, cleaning tools can be readily inserted into the opening to clean both the ascension pipe as well as the supply pipe.

  • Patent number: 4167484
    Abstract: An ozone generating apparatus which comprises a plurality of chambers filled with an adsorbent, wherein a wet raw air is fed through one of the chambers filled with the adsorbent to adsorb moisture to form a dry air and the dry air is fed into an ozonizer to convert it into a dry ozone-containing air, and all or part of the dry ozone-containing air is fed into the other chamber filled with the adsorbent to purge water adsorbed on the adsorbent and to discharge it as a wet ozone containing air. The valves are then switched to feed the wet air to the other chamber filled with the adsorbent, whereby the moisture is adsorbed and the dry ozone-containing air fed from the ozonizer is fed into the former chamber filled with the adsorbent to reactivate the adsorbent and to discharge it as the wet ozone-containing air. The cycle is continuously repeated by switching valves.
