Abstract:
An apparatus and a method for rapidly generating a plurality of isolated effluents have been developed. A specific embodiment involves screening a plurality of solids through simultaneously contacting the members of the plurality with a fluid, sampling the resulting fluids, and processing the resulting fluids to, for example, determine changes as compared to the feed fluid or as compared to other resulting fluids.
Abstract:
Acid washing of silica supports, used for supported tungsten catalysts, improves the activity of the resulting catalyst (i.e., its conversion level at a given temperature) for the metathesis of olefins, without compromising its selectivity to the desired conversion product(s). Exemplary catalysts and processes include those for the production of valuable light olefins such as propylene from a hydrocarbon feedstock comprising ethylene and butylene.

Abstract:
A process and an assembly for simultaneously evaluating a plurality of catalysts is provided wherein the flow rate of a reactive fluid to each of a plurality of reactors is automatically adjusted based on the measured amount of catalyst sample in each reactor to concurrently obtain a substantially identical fluid space velocity in each of the reactors.
Abstract:
A process for evaporating a feed liquid and a process vessel containing both an evaporation zone for evaporating a liquid feed and a treatment zone for treating the resulting vapor uses an evaporation surface to prevent the formation of liquid droplets. The apparatus may comprise an injector having an orifice, the orifice being in the evaporation zone, at least one evaporation surface for evaporating feed and generating vapor, the evaporation surface being located in the evaporation zone, wherein the injector orifice and the evaporation surface are positioned to prevent the formation of a drop at the orifice, a treatment zone for treating the vapor and at least one heater associated with at least a portion of the process vessel.
Abstract:
A process for evaporating liquid feed and conducting multiple treatments to form multiple treatment product comprising: introducing liquid feed to a plurality of process vessels (10) vaporizing the liquid feed within each treatment vessel (10) to form a vapour, and contacting at reaction conditions, vapour in each treatment vessel with a treatment material, to form product. Also claimed is an array of process vessels (10) comprising: a plurality of housings (12), each housing (12) having at least one inlet for liquid feed and at least one outlet (40) for product, each housing (12) encasing an evaporation zone and a reaction zone; at least one heater (20) associated with at least a portion of the housings (12); a plurality of inserts (16) for containing packing for vaporizing the liquid feed to form a vapor, the packing being within the evaporation zones; and a plurality of receptacles (22) with one receptacle (22) placed within each housing (12) and one insert (16) placed in each receptacle, each receptacle retaining treatment material for contacting and treating vapor to form product.
