Definitions
- Particularly useful conditions of calcination comprise heating of the dry catalyst precursor, continuously or intermittently, from a preselected initial elevated temperature which is in a range upward from 250° C to 400° C to a 2 nd elevated temperature which is in the range of from 550° C to 700° C, and ambient, or near ambient, pressure.
- the feedstream can comprise about 5 percent to about 30 percent by weight relative to the total amount of the feed stream, or by mole relative to the amount of propane or isobutane in the feed stream.
- the catalyst compositions described herein are employed in the ammoxidation of propane to acrylonitrile is a once- through process, i.e., it operates without recycle of recovered but unreacted feed materials.
- Processes for recovery and purification of the reaction products include quenching the gaseous reactor effluent with an aqueous quench liquid; forming an aqueous solution comprising the corresponding unsaturated mononitrile, hydrogen cyanide and other organic co-products; and using an integrated sequence of distillations and phase separations to recover for recycle of a useful aqueous liquid, and obtain valuable nitrogen-containing organic compounds and hydrogen cyanide products.
- This example illustrates preparation of a mixed metal oxide catalyst according to the invention by impregnation prior to calcination of a four component base material with a predetermined amount of source of tellurium.
- EXAMPLE 6 This example illustrates preparation of a mixed metal oxide catalyst according to the invention by impregnation of a six component base material with another predetermined amount of source of tellurium.
- a spray dried six components catalyst precursor prepared as described in Example 11 for Precursor B, (Mo, V, Sb, Nb, Ti, and Ce) was calcined in a two step process under nitrogen with an intermediate temperature of 345° C and final temperature of 630° C. 1 gram of the calcined material was weighed into a crucible and put into a 600 furnace for 3 hours, cooled down and weighed. The moisture content of the material was then determined from the weight loss. To determine the pore volume, 0.5 g of material was added to a beaker, and distilled water from a burette was added very slowly with stirring until catalyst reached incipient wetness. The pore volume per gram of catalyst could then be determined.
