Title: Method of calcining and/or sintering material
Inventor: MEYER KURT
IPC: C04B7/44
Filed: 1951-07-13
Abstract: High melting point materials, i.e. carbonates, oxides, sulphates and silicates of the alkaline earth metals, clay, bauxite, phosphates or their mixtures are calcined and/or sintered by arranging them, either inherently containing or mixed with fuel, on a grate in layers of a depth exceeding 50 cms., and up to 3 metres igniting and burning the material by a downdraught air current.  Grain size distribution is such that the coarse fractions lie nearer the grate.  Material poor in fuel and of a finer grain size is applied at the side walls of the furnace to give more even burning.  Poorly or non-sintered material is separated from completely sintered material by sieving, whilst poorly and well calcined material (of non-sinterable material) are gravity separated.  Calcined material may form part of the initial charge.  Specification 709,845 is referred to.ALSO:High melting point materials, e.g. carbonates, oxides, sulphates and silicates of the alkaline earth metals, clay, bauxite, phosphates or their mixtures are calcined and/or sintered by arranging them, either inherently containing or mixed with fuel, on a grate in layers of depth exceeding 50 cms., or in the case of cement exceeding 60 cms. and up to 3 metres, igniting and burning the material by passing a downwardly induced draught of air through the layers.

Title: Improvements in or relating to desulfurization of fluidized coke particles having high sulfur content
IPC: C10L9/04
Filed: 1955-06-14
Abstract: 770,830. Desulphurization of petroleum coke; coking petroleum oils. ESSO RESEARCH & ENGINEERING CO. June 14, 1955 [July 7, 1954], No. 17144/55. Classes 50 and 55 (1). In a process for the desulphurization of or reducing the sulphur content of petroleum coke, containing, e.g. 4-7 per cent by weight of sulphur, the coke particles are contacted with a gas containing free hydrogen at a temperature between 1100‹ and 1800‹ F., preferably 1300‹-1500‹ F., and a pressure between 30 and 300 lbs. per sq. in., preferably 50-250 Ibs. per sq. in., the amount of hydrogen utilized being between 1500 and 6000 v/v/hr., preferably 2500-5000 v/v/hr., where by the sulphur content of the coke is reduced to below 3 per cent by weight. The treatment may last for between 20 minutes and 5 hours and may be conducted while the particles are in the fluidized state, or in a fixed or moving fixed bed. Steam may be added as a diluent to the hydrogen containing gas. The petroleum coke particles are supplied from a process in which a heavy petroleum oil is coked by being sprayed into a fluidized bed of coke particles. The coking zone is maintained at a temperature between 850‹ and 1200‹ F. and a pressure of 1-10 atmospheres and the coke particles have an average size between 100 and 1000 microns. In an example, a coke initially containing 7.1 per cent by weight of sulphur was treated at a temperature of 1300‹ F. and a pressure of 150 lbs. per sq. in. for 1 hour, the sulphur content of the coke being reduced to 1.7 per cent by weight. The rate of flow of hydrogen was 3500 v/v/hr.
