Problems solved by technology

Although catalyst coking can be reduced by operating at elevated hydrogen partial pressure, reduced space velocity, and temperature control in the range of 200°C to 350°C; SCT hydrotreatment under these conditions is not desired , this is because an increase in hydrogen partial pressure will make the process uneconomical due to increased hydrogen and equipment costs, and due to increased hydrogen partial pressure, reduced space velocity, and reduced temperature range will favor undesired hydrogenation reaction

Embodiment 1

[0177] This example illustrates the conversion of steam cracked tars to hydrotreated products.

[0178] The hydrogenation process was carried out in a fixed bed reactor with an approximately 0.3 ID (inner diameter) stainless steel reaction body and three heating blocks. The reactor was heated by a three-zone furnace. Table 1 presents the catalysts used in the experiments. 12.6 grams (17.5 cubic centimeters) of RT-621, 40-60 mesh in size, was charged in the area of ​​the reactor in the furnace.

[0179] Table 1 Description of Catalysts

[0180]

[0181] After loading into the reactor, the unit was tested with molecular hydrogen and nitrogen sequentially at a pressure of 1000 psig (68.9 bar). The catalyst is vulcanized with 200 cubic centimeters of a solution containing 80% by mass fraction of 130N lubricating oil base stock and 20% by mass fraction of diethyl disulfide, based on the weight of the vulcanized solution. Details are as follows:

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application 61 / 529,565, filed August 31, 2011, U.S. Provisional Application 61 / 529,588, filed August 31, 2011, and U.S. Provisional Application 61 / 657,299, filed June 8, 2012 and priority, the entire contents of which are incorporated herein. field of invention [0003] The present invention relates to a hydrotreated product obtained by hydrotreating tars, for example tars obtained from the pyrolysis of hydrocarbons. The invention also relates to a process for the production of the hydrotreated product and to the use of the product, for example, as a fuel oil blending component. Background of the invention [0004] Pyrolysis processes, such as steam cracking, can be used to convert saturated hydrocarbons to high value-added products such as light olefins, eg, ethylene and propylene. In addition to these useful products, hydrocarbon pyrolysis may also produce sig...
