Embodiment 1
[0039] Saudi heavy oil at airspeed 1.0h －1 Entering the reactor, the reaction conditions are: temperature 360°C, pressure 5MPa, mass ratio of methane to Saudi heavy oil 0.05, HZSM-5 content in the catalyst 60%, Si / Al=10, binder SB powder content 38%, active metal The method of equal-volume impregnation is introduced, the content of active metal silver and gallium is 2%, and the catalyst is strip-shaped based on the total weight of the catalyst.
Embodiment 2
[0041] Same as Example 1, only the Saudi heavy oil is used at a space velocity of 1.5h －1 into the reactor.
Embodiment 3
[0043] With embodiment 1, Saudi heavy oil is 2.5h with space velocity －1 into the reactor.

Abstract
The invention discloses a catalyst and a method for heavy oil methanation modification and low-carbon aromatic hydrocarbon rich production simultaneously. The catalyst for heavy oil methanation modification and low-carbon aromatic hydrocarbon rich production comprises, by weight, 60%-70% of a molecular sieve, 30%-40% of a binder and the balance being active metal, wherein the active metal comprises one or more of silver, gallium, zinc, cobalt and molybdenum. The method solves the problems of complex process, high energy consumption, low yield of high-value light oil, high yield of low-value by-products and the like in the existing heavy oil processing process, and meanwhile, the heavy oil methanation modification technology can produce low-carbon aromatic hydrocarbon in a rich way, so thatthe added value of heavy oil processing is increased, and the method is a proper methane comprehensive utilization way.
Description
technical field [0001] The invention relates to the technical field of petrochemical industry, in particular to a catalyst and method for enriching low-carbon aromatics while adding methane to heavy oil. Background technique [0002] In recent years, with the development of the petroleum industry and the continuous exploitation of petroleum resources, the trend of crude oil extracted in the world is becoming heavier, and the amount of sulfur-containing and high-sulfur crude oil, acid-containing and high-acid crude oil, and crude oil with high metal content is increasing , especially with the development and maturity of heavy and extra-heavy oil extraction and processing technology, this trend will become more obvious. In the consumption structure of petroleum products, the demand for light oil products and middle distillates is increasing year by year, the demand for heavy fuel oil is gradually decreasing, and the contradiction between supply and demand of conventional crude...
