摘要： The anode is particularly designed for use at anodic densities D.sub.A greater than 10 kA/m.sup.2, and comprises substantially horizontally extending coated anode segments having a clear spacing of at least 1.5 mm from each other and upwardly extending lateral surfaces. Each segment has an active coated part higher than 5 mm and not exceeding 20 mm, measured from the horizontal undersurface of the anode. The actual active surface of the parts, up to heights of 5 mm, 7.5 mm, 10 mm and 15 mm, respectively, exceeds at least 2.5, 3.33, 4 and 4.7 times, respectively, the projected anode area which latter is the total area bounded by the periphery of the anode. At least half the actual active surface extends upwardly relative to the horizontal base area of the anode.

摘要： A method of making special cokes according to which a mixture of from 50-90% by weight of an atmospheric distillation residue of a petroleum, e.g. a Pannonian petroleum, with a density of from 0.935-0.965 grams per cubic centimeter, a viscosity of from 2.8.degree.-4.3.degree. Engler at 100.degree.C, a sulfur content of from 0.85-1.10%, a coke value according to Conradson of from 5-7 %, an aromatics content of from 40-60%, an asphalt content below 1.8% with a boiling component of less than 20% within the temperature range of from 250.degree.-350.degree.C, and a content in ash forming elements of less than 0.05% is coked together with from 10-50% by weight of a catalyst-free catalytic residue obtained by catalytic cracking of a distillate low in ashes, e.g. gas oil, which last mentioned residue has a density of from 0.90-0.95 grams per cubic centimeter, a viscosity of from 2.5.degree.-3.2.degree. Engler at 50.degree.C, a sulfur content less than 0.6%, a coke value according to Conradson of from 3.5-4.5%, an aromatics content of more than 35%, an asphalt content of less than 0.6%, and boiling components of from 8 to 12% for the range of from 250.degree.-300.degree.C and from 30-40% within the temperature range of from 300.degree.-350.degree.C in a 24 to 48 hour cycle at temperatures of from 475.degree.-515.degree.C and at a pressure of from 3-7 atmospheres above atmospheric pressure at a high recycling ratio.
