摘要： An improved test for quantifying luster of petroleum products in particle form, especially coke, as an index of quality. A representative sample of the product is obtained and prepared. A digital image of the sample is formed using a scanner. The image is then processed digitally to produce a representative luster or optical density measurement for the sample. The preceding process may be repeated several times for each sample and the resultant luster or optical density measurements for each iteration are totaled and averaged. Once the luster measurement or optical density for the sample is obtained, it is compared to established parameters to assign a CTE value to the sample, assuming there is sufficient historical data correlating the two measurements. Various refining operating parameters including feedstocks, temperatures and pressures, may be altered to obtain a desired product.

摘要： An apparatus and method for printing or coating material and supporting the material during printing or coating thereon by either offset-gravure or direct roll equipment includes a cylindrical support member having flexible bristles radiating therefrom. The bristles are of a suitable diameter, length and spacing to form a generally cylindrical brush that is oriented in spaced relation to a contact printing or coating roller and adapted to yield or bend when coming in contact with contoured or uneven portions of the material and thereby fully support the lower surface of the material as the upper surface of the material is being printed upon or coated.

摘要： The present invention includes a process for producing carbon filaments and synthesis gas from a mixture of alkanes, preferably natural gas, comprising converting a first portion of the alkanes, preferably C2+ hydrocarbons, directly to carbon filaments and converting a second portion of the alkanes, preferably methane, to syngas. The natural gas may be separated into a first feed stream comprising ethane, propane, and butane and a second feed stream comprising methane. The first feed stream is fed to a carbon filament CF reactor to produce carbon filaments and hydrogen. The second feed stream is fed to a syngas production reactor to produce syngas. Alternatively, the natural gas is fed to at least one carbon filament reactor that is maintained at an effective temperature to convert C2+ hydrocarbons in the natural gas to carbon filaments and hydrogen, thereby filtering methane from the natural gas.
