摘要: The present invention concerns an improved method of grinding or milling fresh feed (i.e. crushed yet not milled clinker (with or without additions)), using two different grinding agent systems added at specific locations of the cement grinding mill, preferably at two different locations of a cement ball mill, depending on the particle size or fineness of the material to be ground, to reduce the energy needed to achieve a targeted cement fineness or increase the fineness of the cement at constant energy consumption.

摘要: The present invention describes a hydraulic cement composition, process and use thereof, wherein the composition comprises a hydraulic cement composition with increased resistance against carbon dioxide (CO2) for application in reservoirs such as oil and gas and carbon capture and storage (CCS) wells; with improved performance of cement paste formulations as a material for application in primary, secondary cementing, recovery and/or plugging operations, of reservoirs/wells that operate with high CO2 content; as a technological alternative to guarantee the integrity of wells in CO2-rich environments for long periods of time, without any additional intervention to the already current operational procedures for cementing wells, and with cost reduction in relation to class G cement (currently, the main raw material); and sufficient chemical resistance to carry out enhanced oil (EOR) and gas (EGR) recovery by injecting high levels of CO2, increasing reservoir pressure throughout the extraction period of hydrocarbon reservoirs.

摘要: Methods of producing cement using a spent hydrocarbon dehydrogenation catalyst are disclosed. A spent hydrocarbon dehydrogenation catalyst comprising alumina is processed to produce a processed raw material. The processed raw material is then used as a component for producing the cement. Compositions of cement including the processed raw material are disclosed.

摘要: A process to enhance the pozzolanic activity of a natural inactive sedimentary pozzolan and the pozzolanic material formed by the process are described. The process comprises the steps of finely dividing the pozzolan to a Blaine fineness of at least 8,000 cm2/g for increasing the surface area of the finely ground pozzolan and exposing a great amount of the number of silicon and aluminum atoms available to react with lime in a pore solution.

摘要: The present disclosure is related to the field of steel slag treatment, and in particular to a process for stabilizing steel slag, the process comprising subjecting the steel slag to an autoclave treatment by use of a high temperature and pressure saturated vapor at a pressure of 2.0 MPa or above. The process provides the slag with reliable volume stability and makes it possible to meet desired requirements of various building materials. Additionally, the process is low cost, non-polluting, and of very high industrial value.

摘要: A process for reforming the fly ash, including the heating step that heats a raw fly ash powder containing the unburned carbon at a temperature of 780 to 1000° C. to decrease the amount of the unburned carbon contained in the raw fly ash powder; the classifying step that introduces the heat-treated fly ash containing the unburned carbon in decreased amounts obtained through the heating step into a classifying apparatus in the state of being heated at a high temperature so as to separate the fly ash into a coarse powder and a fine powder; the fine powder recovering step that recovers the fine powder of the heat-treated fly ash obtained through the classifying step by using a dust-collecting apparatus; and the milling step that mills the coarse powder of the heat-treated fly ash obtained through the classifying step until a 45 μm sieve residue becomes not more than 34% by mass, and then recovers the milled powder.

摘要: Migration of formation solids in a wellbore is restrained by feeding a slurry, comprising water, a viscosifier, and a concentration of cement clinker particles, into the wellbore, and hydrating the clinker particles in the wellbore. The clinker particles are kept in suspension during the hydrating, and upon completion of the hydrating the hydrated clinker particles form a hardened cement consisting of a permeable structure of interconnected hydrated clinker particles. A layer of degradable lost circulation material (LCM) may be employed to separate the slurry with clinker particles from the formation surrounding the wellbore during hydrating of the clinker particles.
