Molten salt catalytic gasification method of petroleum residue

Abstract

The invention discloses a reaction apparatus used for catalytic gasification of petroleum residues by fuse salt and a method using the same, belonging to the technical field of energy utilization. The reaction apparatus comprises a gasification reaction device and a gas separating and purifying device, wherein the gasification reaction device comprises a shell, the fuse melt is arranged in the inner cavity of the shell, the gas separating and purifying device is connected with the gasification reaction device, and an adsorbent is arranged in the gas separating and purifying device. In usage of the reaction apparatus, the petroleum residues undergo a reaction in the gasification reaction device under the catalysis of the fuse salt so as to obtain a crude synthetic gas product; then the crude synthetic gas product enters the gas separating and purifying device; and impurity particles and gaseous metal ions in the crude synthetic gas product are separated via the adsorbent so as to obtain pure synthetic gas. The reaction apparatus used for catalytic gasification of petroleum residues by the fuse salt and the method using the same realize continuous high-efficiency gasification of the petroleum residues at a low gasification temperature and effectively recover precious metal components in the petroleum residues.

Description

technical field [0001] The invention relates to the technical field of energy utilization, in particular to a method for catalytically gasifying petroleum residue with molten salt. Background technique [0002] In the process of petroleum refining, some residues are inevitably produced. When light crude oil is used for processing, the amount of residue is relatively small, while for heavy crude oil, the amount of residue is relatively large. With the consumption of oil, the stock of light crude oil is getting less and less, so the development and utilization of heavy oil, which accounts for about 40% of crude oil reserves, becomes more and more important. Especially for our country, crude oil is heavy and the supply is insufficient, so it is of special significance to increase the development and utilization of cheaper heavy oil. Correspondingly, the amount of residues produced during petroleum processing will continue to increase, and the average annual output of petroleum...

Problems solved by technology

However, the current related research is still far from perfect, and the research on raw material treatment of petroleum residues, gasification process selection, and recovery of precious metals from petroleum residues is still relatively lacking.

At present, the direct gasification treatment of petroleum residues has problems such as high gasification temperature and high energy consumption, and the existing catalytic gasification process also has problems such as difficulty in adding catalysts, cumbersome recovery process and low efficiency.
