Embodiment 1

[0027] 43kg of cobalt naphthenate, 47kg of nitrate, 2kg of acidified attapulgite, 3kg of glyceryl stearate and 5kg of chlorinated paraffin are physically mixed together to make the catalyst of the present invention.

Embodiment 2

[0029] The present invention uses Venezuelan Orim oil as raw material.

[0030] (1) 95kg Venezuelan Orim oil and the catalyst of 5kg embodiment 1 are mixed homogeneously, and the obtained mixture is sent to distillation unit;

[0031] (2) Under normal pressure and without hydrogen addition, gradually heat the mixed material in the distillation unit to 480°C within 3 hours, obtain dry gas above the distillation unit, and light fuel oil in the middle, and obtain light fuel oil at the bottom of the distillation unit Get petroleum coke.

[0032] The weight yield of light fuel oil is 75-86%, the weight yield of dry gas is 8-16%, and the weight yield of petroleum coke is 6-9%. The technical indicators of light fuel oil are within the range of Table 1.

Embodiment 3

[0034] The invention uses domestic asphalt as raw material.

[0035] (1) 95kg domestic asphalt is heated to liquid state, it is mixed with the catalyst of 5kg embodiment 1, the mixture obtained is sent into distillation unit;

[0036] (2) Under normal pressure and without hydrogen addition, gradually heat the mixed material in the distillation unit to 480°C within 3 hours, obtain dry gas above the distillation unit, and light fuel oil in the middle, and obtain light fuel oil at the bottom of the distillation unit Get petroleum coke.

[0037] The weight yield of light fuel oil is 63-73%, the weight yield of dry gas is 15-17%, and the weight yield of petroleum coke is 12-20%. The technical indicators of light fuel oil are within the range of Table 1.

Abstract

This invention relates to production of light fuel oil from Auli oil, asphalt and super-heavy oil. A catalyst is produced from cobalt naphthenate, nitrate, acid activated clay, glyceryl stearate and chlorparaffins. It can be used at atmosphere and no hydrogenation. Neither waste gas nor wastewater nor dregs is produced. The production is of safety, easy operation, and less investment. Its product can be alternative for diesel oil.

Description

technical field [0001] The present invention relates to a catalyst and method for petroleum refining, more specifically, the present invention relates to a catalyst and method for producing light fuel oil from orim oil, asphalt or extra heavy crude oil from oil fields. Background technique [0002] Orimil, asphalt, and super heavy crude oil from oilfields are difficult to process into light fuel oil in large quantities by traditional petroleum refining technology. Generally, they can only be used as boiler fuel, road paving or building waterproofing, and their utilization value is very low. my country is a big country that consumes oil, especially the demand for diesel oil is more tense, and the comprehensive utilization of oil resources has always been a national concern. [0003] At present, high-temperature, high-pressure, and hydrogenation methods are used at home and abroad to distill light fuel oil from Orimil, bitumen, and super-heavy crude oil in oilfields, which is ...
