发明名称 Clinker and white portland cement with a high sulfur content derived from a high sulfur content pet-coke used as fuel
摘要 The present invention relates to a family of white clinker compositions with a high capacity to fix sulfur derived from a high sulfur content pet-coke used as fuel in the manufacture thereof, which further exhibits low fuel composition and fast setting, achieved by being comprised of the following amounts of clinker phases in percentage by weight: 3CaO.SiO<SUB>2 </SUB>(C<SUB>3</SUB>S): 40 to 75, 2CaO.SiO<SUB>2 </SUB>(C<SUB>2</SUB>S): 10 to 35, 3CaO.Al<SUB>2</SUB>O<SUB>3 </SUB>(C<SUB>3</SUB>A): 0 to 15, CaO.SO<SUB>3 </SUB>(CS): 0 to 10, 4CaO.3Al<SUB>2</SUB>O<SUB>3</SUB>.SO<SUB>3 </SUB>(C<SUB>4</SUB>A<SUB>3</SUB>{hacek over (S): 2 to 15, 11CaO.7Al<SUB>2</SUB>O<SUB>3</SUB>.CaF<SUB>2 </SUB>(C<SUB>11</SUB>A<SUB>7</SUB>.CaF<SUB>2</SUB>): 0 to 5, total % CaF<SUB>2</SUB>: 0.3 to 1.5 measured as CaF<SUB>2</SUB>, % Fe<SUB>2</SUB>O<SUB>3</SUB>: 0 to 0.5 and a SO<SUB>3 </SUB>content between 1.5 to 5% by weight obtained through the calcination of a raw meal containing CaO, SiO<SUB>2</SUB>, Al<SUB>2</SUB>O<SUB>3</SUB>, and CaF<SUB>2</SUB>, using as fuel, pet-coke with a sulfur content higher than 5% and at temperatures between 2192 and 2462° F., without the addition of essentially additive containing SO3 in the raw meal.
