Title: Regeneration of fluidised bed cracking catalysts - under conditions giving low coke content and high activity
Inventor: CASTAGNOS LEONCE FRANCIS
IPC: B01J8/24
Filed: 1975-11-26
Abstract: Catalytic cracking of hydrocarbons in fluidised beds, with regeneration of the catalyst in a bed fluidised with an oxygen-contg. gas, in which the catalyst dwell time in the dense phase is 3-10 mins., to give a coke burn-off rate of 0.12-1.0 kg./kg. catalyst/h., at a temp. of 732-788 degrees C., using a stoichiometric excess of oxygen. A concn. of 1-5 vol. % oxygen and 0-500 ppm. CO is maintained in the waste gas, coke content in the regenerated catalyst reduced to 0.12 wt. % max. and substantially all the CO burnt to CO2 while in the dense phase. After-burning of CO to CO2 in the dilute phase, causing high temps. which damage the cyclones and deactivate the catalyst, is prevented. The catalyst is completely regenerated by removal of coke, and compsn. of the waste gas is held within strict anti-pollution levels.

Title: Magnesium carbonate board mfr. - by mixing neutral carbonate suspension with fibrous substance, partially drying and press forming, and thermally hardening multilayers
IPC: C04B28/10
Filed: 1976-06-24
Abstract: In the title mfr., a suspension of neutral Mg carbonate is mixed with a fibrous material and coats the mixt. on a porous carrier. Water is partially removed and layers are placed on top of each other for press forming and thermal hardening. The process produces a board of higher strength than hitherto and eliminates the use of a mesh carrier through which the suspension can run. Pref. the Mg carbonate is made as a suspension and mixed with a fibrous material, e.g. wood meal, together with further additives, e.g. to give frost resistance. The material content of the suspension is about 10% and it has low viscosity. The suspension brings 200-1000 g matl./m2 to the carrier. The carrier may be on a conveyor band with a suction box underneath for removal of water. The layers so formed are removed on a roller. The assembly of layers is pressed, e.g. hot at a reflective humidity of >=80% and a temp. of 60-100 degrees C, so that neutral Mg carbonate becomes basic and the strength of the board is increased.

Title: Two-stage filtration of beer - having recycle on the second stage to maintain throughput and prevent cake dropping
Inventor: OLBRICH REINER
IPC: B01D37/00
Filed: 1976-07-13
Abstract: Two-stage filtration of beverages uses candle filters with gap type elements in filter vessel and kieselguhr as filter aid. This is mixed into the feed to each filter stage. The filtrate leaving the first stage is mixed with a recycle stream from the second stage before being pumped into the second stage. The quantity of recycle can vary between nil and a gradually increasing amount as the throughput of the first stage declines. The remainder of the output from the second stage is taken as product. A further filtration stage can be added of desired but this also would have recycle. The throughput of the second filter remains approx. constant and only varies slightly. It is equivalent to the initial throughput of the first stage. Used in beverage prepn. esp. of beer. Process provides operation without pressure surges. Erratic operation of the filter is eliminated.

Title: Capillary viscometer with adjustable aperture - having cylindrical probe inside cylinder, the position of the probe being adjustable to evaluate non-Newtonian exponent
Inventor: WINTER HORST AENNING DR ING
IPC: G01N11/04
Filed: 1977-06-25
Abstract: Capillary viscometer has a measurement section consisting of an annular passage formed between the inner wall of a cylindrical boring and a coaxial cylindrical insert (or "thorn"). This insert is mounted downstream of the measurement section, and its posn. along the axis can be adjusted.
