Abstract: An apparatus is disclosed for exchanging heat between solid particles and a heat exchange medium, comprising a housing which housing is provided with aeration means with an inlet for an aeration fluid, with an outlet opening, whereby an aeration zone is defined between the aeration means and the outlet opening, and with heat exchange means with at least one inlet and at least one outlet for the heat exchange medium and extending in at least part of the aeration zone, which apparatus further comprises an inlet conduit for solid particles that extends into the aeration zone. Use of the apparatus for the transfer of heat between a heat exchange medium and solid particles is also disclosed.

Abstract: An apparatus is disclosed for the separation of solids from a mixture of solids and fluid, comprising a housing defining a plurality of separation chambers, each chamber being arranged around a central longitudinal axes and having a curved inner wall such that the intersection of the inner wall and a plane perpendicular to the central longitudinal axes is a concave line, whereby all central longitudinal axes are in one plane, and each chamber having an inlet opening, a solids outlet opening and at least one fluid outlet opening, whereby each fluid outlet opening is in communication with a fluid outlet conduit, and whereby the solids outlet opening of each chamber is in communication with a solids outlet conduit which is in tangential cooperation with the chamber, which apparatus further comprises one supply conduit for the mixture of fluid and solids whereby the supply conduit debouches into a supply opening that is formed by the combined inlet openings of all chambers which openings are communicating with ea

Abstract: An apparatus for particulate solids (e.g. FCC catalyst) regeneration comprising a regenerator housing containing fluidization means arranged below spent-solids inlet means and regenerated-solids outlet means and having fluid in- and outlet means, and further comprising at least one external heat exchanger housing containing heat exchanger means and communicating with the regenerator housing via solids in- and outlet means in which apparatus at least one solids outlet means directly connect a lower section of the heat exchanger housing(s) with a section of the regeneration housing above the fluidization means.

Abstract: An apparatus suitable for solids-fluid (e.g. cracking catalyst/hydrocarbon vapor) separation is disclosed having a plurality of substantially vertical tubular elements disposed within a housing. Inlet means are arranged in the bottom section of the housing and communicate with the space between the tubular elements and the housing. A plurality of tubular fluid outlet means are provided, the lower sections of which are arranged substantially coaxially within the upper sections of said tubular elements and define annular spaces therebetween in which swirl imparting means are arranged. The upper sections of the tubular fluid outlet means cooperate with opening(s) in the upper section of the housing, and the lower sections of the tubular elements communicating with solids outlet means. The invention further relates to a process for separating fluid cracking catalyst particles from gaseous hydrocarbon conversion products and/or flue gases using said apparatus.

Abstract: Process for contacting solid cracking catalyst with a hydrocarbons-comprising mixture by introducing said fluid as a, preferably single, annular stream into a stream comprising the particulate solids.

Abstract: A process is disclosed for catalytic conversion of hydrocarbons (e.g. hydroisomerization of unbranched paraffins) by passing a hydrocarbon-containing feed stream at hydrocarbon conversion conditions sequentially in opposite directions through at least part of a zone containing hydrocarbon conversion catalyst and subsequently through at least part of a zone containing adsorbent material capable of adsorbing unconverted hydrocarbons and sequentially passing a sweep fluid in the same direction as said feed stream through at least part of said zone containing absorbent material.

Abstract: An apparatus suitable for solids-fluid (e.g. cracking catalyst/hydrogen vapor) separation comprising upwardly directed feed inlet means of which the upper part cooperates substantially tangentially with a housing comprising at least a domed upper section, at least one fluid outlet means which is in fluid communication with a central section of the housing, and downwardly directed solids outlet means in communcaition with at least one solids outlet opening in a lower section of the housing. The invention further relates to a process for separating fluid catalytic cracking catalyst particles from gaseous hydrocarbon conversion products and/or flue gases using said apparatus.
