IPC: C10B55/02
Filed: 1937-04-28
Abstract: 494,676. Materials for making coke. ROBERTS, J. April 28, 1937, No. 12089. [Class 55 (ii)] A carbon residue adapted for use in the manufacture of electrodes, fuel or metallurgical coke is obtained by distilling tarry residues such as pitch or bitumen at temperatures not exceeding 700‹ C., crushing and mixing the product with fresh pitch, bitumen or other tar residues in a crushed state and carbonizing the mixture at a temperature exceeding 900‹ C. The semi-coke lumps of the first distillation and the added pitch &c. are preferably crushed to a size such that they will pass through a sieve of # in mesh. The high temperature distillation may be effected in horizontal or vertical retorts of small diameter, e.g. 12-16 in. The proportion of raw pitch added to the product of the first stage is preferably 10-40 per cent of the mixture.

[Class 91] In stabilizing suspensions of coal or like dust in liquid fuel by injected gas, the gas is injected by an atomizer while the liquid is under reduced pressure. For example, oil is circulated from and to a tank a by a pump b and pipe c while air is drawn through a dust filter h, a drying tower g and a pipe e to a slit in a flow-tube or a Venturi throat d type of atomizer ; when several per cent. of air has been mixed in coal dust is admitted from a funnel i. The size of the air bubbles may be 0.1-0.05 mm. under the reduced pressure, e.g. 0.001 atmos. ; that of the coal particles 0.05-0.15 mm.; and 40 lb. of coal to 60 of oil may be used. The vacuum may also be obtained by a vacuum pump connected to the atomizer. A stabilizer, e.g. sodium stearate may be added to the oil ; this also increases the amount of air retained. To improve the combustibility of the fuel the gas used may be oxygen, hydrogen, hydrocarbons, or explosive mixtures.
