Microspheroidal particles, suitable as fluidized bed catalyst supports, are prepared by incorporating a portion of small, preferably recycled, particles into a slurry of inorganic oxide sol and inorganic particles which is spray dried to form microspheroidal particles.

Attrition resistant inorganic microspheroidal particles

A door closet construction includes a door member, including a door frame perimeter, with the door frame perimeter including a closet box extending rearwardly thereof to define a compartmented chamber for containing various articles. The door member includes a closet box door pivotally mounted to the door frame perimeter and coplanar with the door frame perimeter in a closed orientation relative thereto. A modification of the invention includes fiber optic illumination selectively illuminating various chambers within the closet box for indication of articles positioned therewithin and operative through a switch member when the closet box door is opened relative to the closet box.

A process for the preparation of bismuth molybdate catalyst comprising (1) adding a dried mixture of metal salts of the active phase of the catalyst to an aqueous sol containing a support material for the active phase, (2) adding an acid to this slurry, (3) heating the slurry to dryness and (4) calcining the dried precursor to form the catalyst.

Method of preparation of high active phase (AMM)oxidation catalysts with

A process for preparing an attrition resistant molybdenum-containing oxidation catalyst comprising; heat-treating the active catalytic components in an oxidizing atmosphere at a temperature in excess of 175.degree. C.; refluxing the heat-treated oxide catalyst in an aqueous slurry of the required amount of support material; ball milling the resulting catalyst mixture; and subjecting the ball milled catalyst to a second heat-treating step in an oxidizing atmosphere, at a temperature in excess of 200.degree. C.

Maleic anhydride is prepared by reacting n-butene with molecular oxygen at a temperature of about 200.degree. to about 600.degree. C in a fluid-bed reactor using a catalyst charge containing two different catalysts--the first catalyst being one that is especially effective for preparing butadiene from the n-butylenes; and the second catalyst being one that is especially effective for preparing maleic anhydride from butadiene. Unexpectedly, substantial yields of maleic anhydride are obtained.

Preparation of maleic anhydride from n-butene in a one-reactor,

The production of acrylates and methacrylates, made by the oxidative esterification of propylene or isobutylene wherein gaseous reactants are contacted with one or more catalysts and ethylene or an alcohol can be advantageously conducted in a single fluid bed reactor to obtain the desired ester.
