Novel efficient environment-friendly catalyst for regeneration of used oil

Abstract

The invention discloses a novel efficient environment-friendly catalyst for regeneration of used oil. The catalyst is prepared by the following steps: 1, performing ion exchange by using a carrier, a main catalyst, an auxiliary catalyst and a cocatalyst; 2, washing, filtering and drying; 3, forming; and 4, roasting to form a finished product catalyst. The catalyst has the following advantages: (1) the quality of produced oil can be obviously improved; (2) the selectivity to a product diesel oil is high, and the cetane value of the product diesel oil is relatively high, generally is 10-20 units higher than that of catalytic cracking diesel oil; and (3) the safety and catalytic effect are ensured under the condition that the space velocity is ensured to be appropriate, tail oil is ensured to be completely cracked when the used oil is treated from head oil to the end of oil refining, an engine oil component showing a green head is absolutely avoided, moreover, the produced oil does not have a peculiar smell, is clear and not muddy in color, and is close to water white to light yellow, the oil product quality is close to a national standard, the produced oil serves as a diesel engine fuel, the discharged tail gas accords with a corresponding national standard, and the pollution to the atmosphere is greatly reduced.

Description

Technical field [0001] The invention belongs to the technical field of energy regeneration and utilization, in particular to a new type of waste engine oil regeneration high-efficiency environmental protection catalyst. Background technique [0002] The petroleum refining industry is an important basic industrial sector of the national economy. It mainly provides various fuels (such as gasoline, diesel, etc.) for social production, and at the same time provides basic raw materials (such as benzene, phenol, etc.) for the chemical industry. Refining catalyst is an indispensable material used in petroleum refining industry. Since there are a large number of chemical reactions in the petroleum refining process, and the catalyst can change the chemical reaction rate and shorten the reaction time, its performance is directly related to the economic benefits of the petroleum refining industry. On the other hand, because the catalyst can also ease the reaction conditions, the petroleum ...

Problems solved by technology

If you continue to generate high-quality fuel oil, you need acid-base treatment, but as we all know, acid-base treatment will consume a considerable part of the oil, and the resulting acid residue and alkali residue will cause serious pollution to the environment, which is a national decree Prohibited behavior, this is a common problem of domestic small oil refineries
