摘要： The invention relates to a method of converting hydrocarbons. According to the method, a gaseous or liquid hydrocarbon feed is passed into a circulating fluidized-bed reactor, wherein the feed is converted at a high temperature under the influence of particulate matter kept in a fluidized state, and the converted hydrocarbon products are removed from the reactor in a gaseous phase. According to the invention, a circulating fluidized-bed reactor (1-3; 41-43) is used having an axially annular cross section and being equipped with a multiport cyclone (14, 17; 52, 63) for the separation of the particulate matter from the gas-phase reaction products. The reaction space comprises an intershell riser space (13; 50) formed between two concentrically located cylindrical and/or conical envelope surfaces. The separation of particulate matter from the gas-phase reaction products is performed by means of a multiport cyclone equipped with louvered vanes (14; 63).

摘要： The present invention relates to a modified fiber product and a method of producing same. According to the method, the cellulosic raw material is formed into a fiber suspension, into which components modifying the properties of the fibers are added, subsequent to which the fibrous material is dried in connection with, for example, web forming. According to the invention, alkyl derivative of cellulose is mixed into the fiber suspension in alkaline conditions, the derivative being at least partly dissolved in water, and the derivative is allowed to be sorbed into the fibrous material prior to drying such that the sorbed cellulose derivative can not be washed off with water. The strength properties or the water retention of paper and paperboard products can be improved by using the invention.

摘要： The present invention concerns a method of preparing pharmaceutical compositions of a biologically active proteins, in particular multicomponent interferon compositions. The invention comprises the steps of adding to a solution of the protein a non-ionic detergent in an efficient amount to provide an extended shelf-life of the pharmaceutical composition; subjecting the solution containing the non-ionic detergent to filtration on a virus removal filter with a pore size of 10 to 40 nm; and recovering the filtrate. The method gives rise to, e.g., a virus-safe multicomponent α-interferon composition, comprising a non-ionic detergent as a stabilizer in an amount exceeding the critical micellar concentration of the detergent and being essentially free from substances retained on a virus-filter having high virus retentive capacity.

摘要： The invention relates to a method of separating solids from a gas flow in a fluidized catalytic process and to a cyclone assembly suited for use in a fluidized catalytic process. According to the invention, the gas flow of the process carrying the suspended solids is passed into a separation assembly, wherein the solids are separated from the gaseous phase under the effect of the centrifugal force, whereby a multiport cyclone is used as the separation assembly, into which the gas flow to be treated is passed via an inlet nozzle having an axially annular cross section. The use of the multiport cyclone, e.g., in an FCC process give significant advantages in flow dynamics and process engineering over conventional arrangements and generally used single-port cyclones.

摘要： The present invention concerns a method and an apparatus of introducing polymer slurry obtained from a slurry reactor into a gas phase reactor containing a fluidized bed (C, D). According to the present invention, the content of the slurry reactor (R1) is conducted directly to the fluidized bed reactor (R2) as a multi-phase stream comprising polymer, active catalyst and reaction medium using at least one feed line (10; 11; 12), and the stream is fed below a first fluidized zone (C) of the gas phase reactor via inlet pipe protruding into the fluidized bed in order to increase the once-through conversion of the process. By means of the invention, the amount of unreacted monomers which needs to be recirculated is minimized and investment and operation costs of the recovery section are greatly reduced.

摘要： The present invention concerns nucleated propylene polymers having a xylene soluble fraction at 23 °C of less than 2.5 %, a crystallization temperature of over 124 °C and a tensile modulus of greater than 2,000 MPa. These polymers can be prepared by nucleating a propylene polymer with a polymeric nucleating agent containing vinyl compound units, and by polymerizing propylene optionally with comonomers in the presence of a Ziegler-Natta catalyst system primarily transesterified with a phthalic acid ester - a lower alcohol pair to provide said propylene polymer. The catalyst contains a strongly coordinating external donor.

摘要： This invention concerns a process and equipment for producing precipitated calcium carbonate. According to the process, limestone is burnt at a high temperature to form calcium oxide and, thereafter, calcium carbonate is formed from calcium oxide in the presence of water and carbonate ions and the formed calcium carbonate is recovered. The formation of the carbonate may be performed by carbonating calcium oxide with carbon dioxide gas in the presence of water or water vapour, or by reacting calcium oxide with soda solution. According to the invention calcium oxide is converted to calcium carbonate without separate slaking and essentially without intermediate storage, in particular without intermediate storage between the burning of the starting material and the forming of calcium carbonate. With the aid of the invention a quite advantageous solution in view of heat economy is achieved.

摘要： The invention relates to a process and apparatus for pretreating pulp raw material, to be subsequently prepared in a chemical pulping process, and for preparing cellulose pulp from a fibrous starting material. According to the process the starting material is delignified to yield a chemical cellulose pulp, and the obtained pulp is bleached when desirable. According to the invention the starting material is crushed in cooking liquor prior to delignification in order to open its fiber structure. The apparatus of the invention comprises a frame (21), to which two adjacent first rolls (12; 22, 23) have been fitted, which form a first pair of rolls with the rolls arranged to distance from each other in such a manner that a gap clearance is formed between their outer mantles. The rolls are caused to rotate by a means of power transmission, which causes the raw material to be crushed inside the gap between the rolls where a liquid pocket is formed, from which liquid is absorbed into the fiber material being treated. The invention provides even cooking of the raw material under mild conditions.

摘要： The present invention concerns a process for producing a polymer blend comprising a first phase containing a polyacrylate polymer prepared by radical polymerization and a source of radicals, and a second phase containing a polyolefin polymer. According to the invention, the blend is compounded by melt processing and the termination reactions of free radicals derived from the source of radicals are preferably retarded by introducing N,N'-m-phenylene-dimaleimide or a similar peroxide accelerator into the blend before melt blending thereof. The introduction of a peroxide accelerator will promote formation of cross-links in the polyacrylate phase and thus improve the elastomeric properties of the blend.
