  • Patent number: 9732284
    Abstract: A process and apparatus is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a catalyst comprising iron oxide and alumina to form a heavy hydrocarbon slurry and hydrocracked to produce lighter hydrocarbons. The slurry hydrocracking reaction can be controlled by measuring the production of mesophase using X-ray diffraction. Upon a mesophase yield fraction reaching a predetermined level, reaction conditions should be moderated to avoid excessive coke production.
    Type: Grant

  • Patent number: 6858769
    Abstract: A catalyst for the selective oxidation of hydrogen has been developed. It comprises an inert core such as cordierite and an outer layer comprising a lithium aluminate support. The support has dispersed thereon a platinum group metal and a promoter metal, e.g. platinum and tin respectively. This catalyst is particularly effective in the selective oxidation of hydrogen in a dehydrogenation process.

  • Patent number: 6806093
    Abstract: An apparatus and process for forming an array of powder samples arranged in predefined locations where all samples have a flat surface in a common plane has been developed. A monolithic block having a main support section having at least N perforations from a first surface of the main support through a second surface of the main support in predefined locations, where N is the number of samples in the array is provided. The monolithic block also has a flat support section covering the perforations of the main support section. All N samples are loaded simultaneously with sample X in perforation X of the main support where X is an integer from 1 to N. A flat surface of each sample where the flat surfaces are a common plane is formed by forcing the samples within the perforations against the flat support.

  • Patent number: 6677162
    Abstract: A process of forming an array of powder samples arranged in predefined locations where all samples have a flat surface in a common plane has been developed. A main support having at least N perforations from a first surface of the main support through a second surface of the main support in predefined locations, where N is the number of samples in the array is provided. The main support is equipped with a flat support temporarily attached to its first surface. All N samples are loaded simultaneously with sample X in perforation X of the main support where X is an integer from 1 to N. A flat surface of each sample where the flat surfaces are a common plane is formed by forcing the samples within the perforations against the flat support. The samples are retained in position within the perforations against the flat support, and are made ready for analysis by exposing the flat surfaces of the samples by removing the flat support.

  • Patent number: 6514904
    Abstract: A catalyst and a process for using the catalyst are disclosed generally for the conversion of hydrocarbons. By the use of at least one high temperature calcination under dry conditions, a catalyst with a beneficial combination of lowered surface area and excellent piece crush is created. X-ray diffraction pattern information is used to distinguish the resulting product.

  • Patent number: 6503866
    Abstract: A process for preparing a catalyst, the catalyst itself, and a process for using the catalyst are disclosed generally for the conversion of hydrocarbons. By the use of at least one high temperature calcination under substantially dry conditions, a catalyst with a beneficial combination of lowered surface area and excellent piece crush is created. X-ray diffraction pattern information is used to distinguish the resulting product.

  • Patent number: 5059737
    Abstract: A hydrocarbon conversion process which utilizes a solid phosphoric acid catalyst having a total X-ray intensity of at least 40 percent relative to alpha-alumina. The solid phosphoric acid catalyst is produced by crystallizing an amorphous mixture of an acid oxide of phosphorus and a siliceous material at a temperature of from 350.degree. to 450.degree. C. and in the presence of from 10 to 50 mole percent water vapor based upon the total vapor rate to the crystallizing means. Embodiments of the new hydrocarbon conversion process include alkylation, oligomerization, and hydration, of hydrocarbons and oxygenated hydrocarbons.
