Embodiment

[0052] For verifying the effect of the inventive method, adopt figure 1 In the process flow shown, the Venezuelan vacuum residue is used as the inferior heavy oil raw material A to be processed, and the properties of the vacuum residue are shown in Table 1. The properties of the contact agent used are shown in Table 2. The conditions for the contact reaction between inferior heavy oil raw material A and the contact agent are shown in Table 3, and the composition of the product is shown in Table 4.

[0053] Preheat inferior heavy oil raw material A to 300°C, and then introduce it into riser reactor 4, at a weight hourly space velocity of 5h -1 , the contact reaction with the contact agent is carried out under the condition of agent-oil ratio 7-8, the reaction temperature in the reactor is 480°C, the liquid product yield exceeds 70wt%, the coke yield is close to the residual carbon value of the raw material, and the residual carbon removal rate is close to 90% %, the removal r...

Abstract

The invention provides a method for simultaneously treating inferior heavy oil and producing synthetic gas. The method comprises the following steps: contacting the inferior heavy oil raw material with a catalyst for reacting and separating oil and gas generated in the reaction from the spent catalyst, putting the spent catalyst in countercurrent contact with oxygen-containing gas to have a charcoaling reaction so as to a semi-regenerative catalyst until the temperature of the spent catalyst rises to the temperature required by a gasification reaction, and finally, contacting the semi-regenerative catalyst with water vapor to have the gasification reaction, thereby generating the synthetic gas and the regenerated catalyst. The method for simultaneously treating the inferior heavy oil and producing the synthetic gas is capable of effectively utilizing coke generated in the treatment process while performing efficient treatment of conversion to light fraction on the inferior heavy oil, and the generated synthetic gas yield is increased.

Description

technical field [0001] The invention relates to a method for processing inferior heavy oil and producing syngas, belonging to the technical field of petroleum processing. Background technique [0002] With the rapid development of the world economy and the increasing demand for oil, conventional oil reserves are decreasing day by day. As an unconventional oil resource, low-quality heavy oil will become one of the important energy resources in the 21st century. However, on the one hand, inferior heavy oil cannot be directly used as fuel oil and road asphalt due to its own properties and environmental protection regulations. There are many problems with traditional technology processing such as asphalt. Therefore, it is necessary to decarburize and remove heavy metals from inferior heavy oil to provide relatively clean raw materials for downstream processes. [0003] In the upgrading process of inferior heavy oil, due to the high residual carbon value of inferior heavy oil, ...
