Embodiment

[0163] The properties of medium-temperature coal tar are shown in Table 1. It is separated into a light fraction with a weight yield of 82% mainly composed of hydrocarbons with a conventional boiling point lower than 480°C and a weight yield of 18% with a weight yield mainly composed of hydrocarbons with a conventional boiling point higher than 480°C. The coal tar pitch, the light fraction alone undergoes deep hydrogenation upgrading, and the coal tar pitch is used as a high aromatics raw material for HDS.

[0164] The hydrogen-donating hydrocarbon stream SHS is selected from the pre-hydrogenated oil R1P obtained in the pre-hydrogenation reaction process R1, the amount is 5 times that of the high-aromatic raw material HDS, and is obtained through the gas-liquid separation process of the pre-hydrogenation reaction effluent R1P. At this time, the supply The hydrogen hydrocarbon precursor stream is the high-aromatic raw material HDS itself; the weight ratio of the hydrogen-donatin...

Abstract

The invention relates to an up-flow type reactor, which comprises a lower section catalysis reaction zone and an upper section gas-liquid separation zone, wherein 1, 2 or multiple catalyst bed layers are arranged at the lower section catalysis reaction zone, a liquid collection chamber is arranged at the upper section gas-liquid separation zone; the catalyst bed layer can be a stationary bed, a micro-expansion bed and/or an online replacing bed; in the material flowing direction in the reactor, the lower section catalysis reaction zone and the upper section gas-liquid separation zone are in series connection. According to the invention, the functions of the up-flow type reactor and the reactant gas-liquid separator are combined, the structure of the separator is simplified and the separation efficiency is improved; the structure is particularly suitable for a pre-hydrogenation reactor during low and medium temperature coal tar deep hydrogenation modification process; the liquid exhausted from the liquid collection chamber of the separator can be used as circulating oil to return to an upstream process; the rest liquid and/or gas enter/enters a deep hydrogenation modification reactor as a pre-hydrogenation reactant; or the liquid exhausted from the liquid collection chamber of the separator and the gas exhausted from the gas phase space of the separator are subjected to post treatment respectively.

Description

technical field [0001] The invention relates to an upflow reactor, which combines an upflow catalytic reaction zone and a reaction product gas-liquid separation zone operated in series, including a catalytic reaction zone with one or two or more catalyst beds, namely the lower section and the The gas-liquid separation area of ​​the liquid collection chamber is the upper section; in particular, the present invention relates to an up-flow type catalytic reaction area and a series-operated reaction product gas-liquid separation area for hydrocarbon hydrogenation process. Reactor; more particularly, the present invention relates to a combination of an upflow catalytic reaction zone and a series-operated reaction product gas-liquid separation zone used in a medium-low temperature coal tar deep hydrogenation upgrading process, especially a pre-hydrogenation process upflow reactor. Background technique [0002] A prior art upflow hydrogenation reactor or upflow hydrogenation react...
