A method for producing a multimetal oxide catalyst comprises preparation of a precursor composition, exposing said precursor composition to elevated temperatures to activate the composition, and grinding the activated composition. The preparation of the precursor composition comprises: a) forming a plasticized precursor composition from the constituents of the composition; b) discharging the plasticized precursor composition from an extruder having at least one die to form extrudates; c) allowing the extrudates to drop onto a transfer surface disposed beneath the at least one die whereby the extrudates break into pieces which come to rest on the transfer surface; d) transferring the pieces to at least one drying chamber; and e) moving the pieces, through the at least one drying chamber on an air permeable drying conveyor belt; wherein steps b) through d) are carried out under reduced pressure. The method allows the production of a multimetal oxide catalyst with uniform characteristics. Fine particles of the multimetal oxide precursor that may be generated during extrusion of the plasticized precursor composition and handling of the extrudates are removed.

A continuous granulation system for obtaining conditioned granules is disclosed. The system comprises a processor configured to produce a continuous flow of granules at an outlet of the processor. The system also comprises a collection chamber positioned downstream from the processor and configured to collect the granules from the outlet. Further, the system comprises an air displacement device coupled to the collection chamber and configured to create a unidirectional flow of air at the outlet in a direction of the granules exiting the processor and away from the outlet. The unidirectional flow of air conditions the granules obtained in the collection chamber. A continuous granulation method and a continuous granule collection system for obtaining the conditioned granules is also disclosed.

A method of production of a homogeneous powdered product from a starting product in a liquid state, the starting product having sugars as at least 60% of its total solids, the method comprising: in the absence of air; pressurizing the starting product to a pressure greater than 1 bar; injecting a gas into the starting product to form a mixture in which the starting product is substantially saturated by the gas; and degassing the mixture into a continuous stream of transport gas such that, on contact with the transport gas, water from the mixture evaporates to leave the homogeneous powdered product.

A machine for shredding portions of bituminous material in the solid-state into granules in the solid-state. The machine comprises a pressing member provided with a piston which is axially mobile inside a perforated tubular body along an axis and is provided on the head thereof with an internal concave portion having a shape substantially complementary to a projecting part present in an axial end of the perforated tubular body. On the head of the piston through-openings are made, which extend radially along a direction approximately transversal to the axis and are in communication with the internal space of the concave portion.

A process can be used for producing (rigid) particle foams from polymer compositions containing at least one polymer having a glass transition temperature according to ISO 11357-2 of at least 180° C. with an underwater pelletization system.

A pelletizing apparatus for the production of pellets from a melt flow comprising a pelletizer (12, 112), a cutting chamber (14, 114, 172), and a suspension structure (4, 104) for suspension of the pelletizer (12, 112) and/or the cutting chamber, wherein the suspension structure (4, 104) has a stationary portion (8, 108) and a portion (6, 106) connected rotatably about an axis of rotation (18, 118) to the stationary portion (8, 108) by means of a joint (16, 116).

According to the invention it is proposed that the pivotable portion (6, 106) has a substantially horizontal support arm (20, 120) which extends from the axis of rotation (18, 118) and has a distal end (22, 122), wherein in the region of the distal end (22, 122) the pivotable portion (6, 106) has a support (10, 110) adapted to support the pivotable portion (6, 106) in a vertical direction (24, 124).
