Problems solved by technology

[0006] It is very important to determine the octane number during reforming using laboratory equipment using analytical characterization rather than on the engine test bench to determine the anti-knock properties of gasoline, firstly to avoid the production of samples on a half-liter scale, which is extremely expensive
Second, this would yield extremely low octane time resolution, as these samples would have to be collected over long periods of time and would therefore only produce an average for that time interval

Embodiment

[0105]To illustrate the process according to the invention, a test run was carried out using five different catalysts under naphtha reforming conditions. Commercially produced catalysts were used, specifically about 9 grams (g) of catalyst per reactor. The duration of the study is 200 hours, of which image 3 The results shown are intervals for the 10-hour time range. Each experiment was performed so that the octane number was kept constant, which can be found at image 3 see in the upper part of . The temperature of each reactor was continuously increased in order to compensate for the loss of activity seen in conjunction with catalyst aging. On average, the temperature was increased by 1.5°C to 5°C each time over the 200 hour period in order to maintain the octane number of the product fluid stream within a constant range. Octane measurements exhibit a standard deviation of ±0.3. It should be noted that this is an extremely small standard deviation not yet published in ...

Abstract

The invention relates to a device and a method for examining the naphtha reformation process in catalyst test devices, comprising reactors arranged in parallel. The device has a plurality of reactors arranged in parallel comprising reaction chambers (R1, R2,...), a reactant fluid supply, a process controller, and at least one analysis unit. Each individual reactor has an outlet line for the flow of a product fluid, said analysis unit being operatively connected to each outlet line for the flow of the product fluid, and the device functionally correlates to the control of the device. In the method, naphtha-containing reactant fluid flows are brought into contact with catalysts in the individual reactors, and the flows of the product fluid are subsequently supplied to the online analysis unit from the respective outlet lines of the individual reactors and analyzed. Using the analysis of the online analytic characterization data, the process parameters of the respective reactor unit are adapted. The method steps of analytic characterization, analysis, and adaptation of process parameters are repeated for the duration of the examination.

Description

technical field [0001] The present invention relates to a method, preferably a laboratory method, for studying a naphtha reforming process in a catalyst test rig, preferably in a catalyst test rig with reactors arranged in parallel. Background technique [0002] Naphtha reforming is used to catalytically react gasoline base stock (naphtha) and light oils in order to convert these into higher grade fuels (gasoline) and chemicals (aromatics). Naphtha reforming is of great economic and technological importance due to the high demand for fuels and base chemicals. In addition, naphtha reforming produces hydrogen that is critically needed for hydroprocessing in refineries. In particular, efforts are being made to further develop and improve naphtha reforming in order to increase the yield of reformed products (gasoline, aromatics) per barrel of naphtha and thus preserve the precious resource. [0003] This document relates to the use of such a catalyst testing device for carryin...
