SOLID-LIQUID SEPARATION SYSTEM

Methods and apparatus for separating liquid products and catalyst fines from a slurry used in a Fischer-Tropsch reactor. A settling system continuously or intermittently removes catalyst fines from the slurry and is coupled with catalyst-liquid separation system that separates liquid products from the slurry. The preferred separation system produces a sub-particle rich stream and a catalyst-lean stream that are removed from the system. The systems of the present invention act to reduce the concentration of catalyst fines in the reactor, thereby increasing the effectiveness of a catalyst-liquid separation system.

CATALYTIC REACTOR DESIGNED TO REDUCE CATALYST SLUMPING AND CRUSHING

A vertical catalytic reactor for steam reforming a reactor fuel into a product gas, the catalytic reactor containing a catalyst forming a catalyst bed. If the catalytic reactor material has a thermal coefficient of expansion greater than the catalyst, then the catalytic reactor experiences problems due to thermal cycling. During the start-up of the catalytic reactor, the temperature increase causes the catalytic reactor to expand more than the catalyst, thus, the catalyst slumps within the catalytic reactor. During the shut-down of the catalytic reactor, the temperature decrease causes the catalytic reactor to contract and crush the slumped catalyst. The catalytic reactor incorporates a design (100) for reducing catalyst slumping and crushing.

The fluidised substrate has below it a lazer of distributor ²particles through which the fluidising medium passes prior to contact with the ²fluidised substrate and biomass associated therewith. The effect of the ²distributor layer is that the particles damp out excessive turbulence in the ²fluidising medium thus preventing undue turbulence of the medium within the ²fluidised layer. This has the advantage of controlling, to some extent, the ²thickness of the biofilm, which maz be carried by the fluidised substrate ²particles. The particles may be recycles (1, 2, 5) through the distributor ²layer where the action of the distributor particles serve to strip exces ²biofilm from the substrate particles which latter are then returned to the ²fluidised bed.² ...

СПОСОБ РЕГУЛИРОВАНИЯ ТЕЧЕНИЯ ПОЛИМЕРА В ПРОЦЕССЕ ПОЛИМЕРИЗАЦИИ

FIELD: chemistry. ^ SUBSTANCE: invention relates to a continuous method for gas-phase polymerisation of monomers such as -olefins, in the presence of a polymerisation catalyst, and particularly to a method of regulating fluidity of polymer particles flowing inside a gas-phase polymerisation reactor. A stream of liquid with mass flow per unit surface area of the reactor exceeding 30 kg/h m2 is continuously fed into the polymerisation reactor in which density of solid substance measured in kg of polymer per m3 of the reactor occupied by the polymer exceeds 80% of "bulk density" of the polymer. The liquid is fed at minimum pressure near the wall of the reactor. The liquid used is part of fresh polymerised monomers in condensed form and/or liquid obtained after cooling and condensing a stream of gas taken for recycling from the polymerisation reactor. ^ EFFECT: regulation of fluidity of polymer particles in a downward current of the reactor column prevents formation of polymer lumps and clogging and provides stable operation of industrial polymerisation equipment. ^ 6 cl, 1 dwg, 4 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 380 379 (13) C2 (51) МПК C08F 2/34 (2006.01) C08F 10/00 (2006.01) B01J 8/22 (2006.01) B01J 8/20 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ, ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21), (22) Заявка: 2006134738/04, 31.01.2005 (24) Дата начала отсчета срока действия патента: 31.01.2005 (72) Автор(ы): МЕИ Габриеле (IT), БЕРТОЛИНИ Стефано (IT) R U (73) Патентообладатель(и): БАЗЕЛЛЬ ПОЛИОЛЕФИН ИТАЛИЯ С.Р.Л.

IMPROVEMENTS IN AND RELATING TO FLUID BED EXPANSION AND FLUIDISATION

Method and apparatus (8) in which a biomass is carried on a substrate which is fluidised. The fluidised substrate has below it a lazer of distributor particles through which the fluidising medium passes prior to contact with the fluidised substrate and biomass associated therewith. The effect of the distributor layer is that the particles damp out excessive turbulence in the fluidising medium thus preventing undue turbulence of the medium within the fluidised layer. This has the advantage of controlling, to some extent, the thickness of the biofilm, which maz be carried by the fluidised substrate particles. The particles may be recycles (1, 2, 5) through the distributor layer where the action of the distributor particles serve to strip exces biofilm from the substrate particles which latter are then returned to the fluidised bed.

Fluid bed expansion and fluidisation

Method and apparatus ( 8 ) in which a biomass is carried on a substrate which is fluidised. The fluidised substrate has below it a lazer of distributor particles through which the fluidising medium passes prior to contact with the fluidised substrate and biomass associated therewith. The effect of the distributor layer is that the particles damp out excessive turbulence in the fluidising medium thus preventing undue turbulence of the medium within the fluidised layer.

Slurry bubble column reactor

A slurry bubble column reactor comprising: a slurry zone arranged to contain in use a volume of slurry comprising a liquid phase in which solid particles are suspended; a gas space above the slurry zone; gas supply apparatus (11) arranged to supply gas to the slurry zone; a gas outlet from the gas space; and a liquid outlet. The gas supply apparatus (11) comprises a gas supply pipe (13), gas manifolds (14) tubular distribution rings (20-24) and a set of gas nozzles (40). The nozzles (40) open downwards and are arranged in use to inject gas into the slurry zone of the reactor (11), thereby forming downwardly extending gas jets of length L in the slurry. The nozzles (40) are distributed generally evenly across the cross section of the reactor (11) and are arranged to direct their gas jets towards the bottom of the reactor (11), in order to dislodge settling catalyst particles.
