摘要:
This invention is directed to processes (i.e., methods) for making methanol compositions, and to processes (i.e., methods) of using the methanol compositions. The methanol compositions contain ethanol and are particularly suitable for contacting with an olefin forming catalyst to form an olefin stream.
摘要:
This invention concerns processes for converting oxygenates to olefins that include a step of pretreating catalyst used in the conversion reaction. A fresh or regenerated metalloaluminophosphate molecular sieve, which is low in carbon content, is pretreated with an aldehyde. The aldehyde forms a hydrocarbon cocatalyst within the pore structure of the molecular sieve, and the pretreated molecular sieve containing the co-catalyst is used to convert oxygenate to an olefin product.
摘要:
Disclosed is a crystalline silicoaluminophosphate molecular sieve comprising a porous framework structure and at least one single ring aromatic compound within the porous framework structure. The silicoaluminophosphate molecular sieve is used to convert oxygenate feedstock to olefin product. The olefin product is high in ethylene and propylene content, with a high selectivity to ethylene. The silicoaluminophosphate molecular sieve can be included with a binder and other materials in finished catalyst form.
摘要:
The invention relates to a hydroprocessed product that can be produced by hydroprocessing tar, such as a tar obtained from hydrocarbon pyrolysis. The invention also relates to methods for producing such a hydroprocessed product, and the use of such a product, e.g., as a fuel oil blending component.
摘要:
In a process for the dehydrogenation of dehydrogenatable hydrocarbons, a feed comprising dehydrogenatable hydrocarbons is contacted with a catalyst comprising a support and a dehydrogenation component under dehydrogenation conditions effective to convert at least a portion of the dehydrogenatable hydrocarbons in the feed. The catalyst is produced by a method comprising treating the support with a liquid composition comprising the dehydrogenation component or a precursor thereof and at least one organic dispersant selected from an amino alcohol and an amino acid.
摘要:
In a process for the dehydrogenation of cyclohexanone to produce phenol, a feed comprising cyclohexanone is contacted with a dehydrogenation catalyst under dehydrogenation conditions comprising a temperature of less than 400° C. and a pressure of less than 690 kPa, gauge, such 0.1 to 50 wt % of the cyclohexanone in said feed is converted to phenol and the dehydrogenation product contains less than 100 ppm by weight of alkylbenzenes.
摘要:
Techniques for data migration of a storage system are described herein. According to one embodiment, a list of files stored in a source storage tier is identified as candidate files to be migrated to a target storage tier based on a migration policy. One of a regular data movement method and a bulk data movement method is selected based on a characteristic of the candidate files. The candidate files are then migrated from the source storage tier to the target storage tier using the selected data movement method.
摘要:
A method, article of manufacture, and apparatus for transferring data from a source tier to a target tier. In some embodiments, this may include applying a policy to an object in the source tier, determining the target tier based on the policy, and moving the object from the source tier to the target tier based on the policy. In some embodiments, determining the target tier based on the policy may include determining a higher target tier. In some embodiments, determining the target tier based on the policy may include determining a lower target tier.

The invention relates to upgraded pyrolysis products, processes for upgrading products obtained from hydrocarbon pyrolysis, equipment useful for such processes, and the use of upgraded pyrolysis products.
摘要:
In a process for the dehydrogenation of cyclohexanone to produce phenol, a feed comprising cyclohexanone is contacted with a catalyst comprising an inorganic, crystalline, mesoporous support material and a hydrogenation-dehydrogenation component under dehydrogenation conditions effective to convert at least part of the cyclohexanone in the feed into phenol and hydrogen.
