    • A process for hydroformylation of an olefin, which comprises reacting an olefin with carbon monoxide and hydrogen in the presence of a rhodium catalyst having a trivalent organic phosphorus compound as a ligand, wherein the hydroformylation reaction is conducted by two stage reactor systems i.e., a first stage reactor system comprising a reactor or reactors having a mixing characteristic of the liquid phase being substantially of complete mixing type, and a second stage reactor system being a reaction system of a catalyst solution circulating type and comprising a reactor or reactors having a mixing characteristic of piston flow type wherein when the mixing characteristic of the liquid phase is represented by a diffusion model, a non-dimensional number U (hereafter referred to as a "flow mixing parameter") defined by the formula (I):U.tbd.uL/2E (I)wherein u is an average flow velocity (cm/sec), L is the length (cm) of the reaction layer, and E is an average diffusion coefficient (cm.sup.2 /sec), is at least 0.4, a gaseous product or gas-liquid mixture discharged from the first stage reactor system, is separated into a stream containing the unreacted olefin and other stream, and a part or whole of the stream containing the unreacted olefin is supplied to the second stage reactor system.

    • A cement composition, and a process for producing a cement composition, wherein the cement composition has the Sr content of 0.065 mass % to 1.0 mass % and the MgO content of greater than 1.0 mass % to 3.0 mass %. The process for producing a cement composition comprises a step (A) of adjusting the basic raw material units of raw materials selected from the group consisting of limestone, silica stone, coal ash, clay, blast furnace slag, soil generated by construction work, sewage sludge, hydrocake and iron sources so that the cement composition has the Sr content of 0.065 mass % to 1.0 mass % and the MgO content of greater than 1.0 mass % to 3.0 mass %, blending the adjusted raw materials and burning to produce cement clinker, and a step (B) of mixing the cement clinker with gypsum and an admixture of limestone and blast furnace slag followed by grinding.
    • 水泥组合物和水泥组合物的制造方法,其中,所述水泥组合物的Sr含量为0.065质量%〜1.0质量%,MgO含量大于1.0质量%〜3.0质量%。 水泥组合物的制造方法包括:调整从石灰石,硅石,煤灰,粘土,高炉矿渣,建筑工程产生的土壤,污水中选出的原料的基本原料单位的工序(A) 污泥,水泥和铁源,使得水泥组合物的Sr含量为0.065质量%至1.0质量%,MgO含量大于1.0质量%至3.0质量%,将调整后的原料混合并燃烧以生产水泥熟料, 以及将水泥熟料与石膏混合的石灰石和高炉矿渣的混合物的步骤(B),随后研磨。
