Abstract
The present invention provides a hydrogen cracking catalyst for a slag oil suspension bed, which is prepared by the way that four nitrate solutions including nickel nitrate, manganese nitrate, ferric nitrate and cobalt nitrate are diluted by water after being mixed, wherein the mixed solution of the four kinds of nitrates comprises 50 to 80% of nickel nitrate, 10 to 30% of manganese nitrate, 4 to 20% of ferric nitrate and 0.5 to 5% of cobalt nitrate according to the proportion by weight. The pH value of the mixed solution is not greater than 3 after the water is added to the mixed solution. Compared with the other type of hydrogenation catalysts for the suspension bed, the hydrogen cracking catalyst has the obvious advantages that the cost is lowered greatly because the raw materials are easily obtained with low cost, and the operation cost of the hydrogenation process of the slag oil suspension bed of thick oil is greatly reduced because the hydrogenation is basically equivalent to the cracking activity. Thereby, the hydrogen cracking catalyst has very significant significances and obvious economic benefits for developing the thick oil processing, increasing the yield of middle distillate and light oil, increasing the quality of oil products, reinforcing the operation flexibility of the device, and developing the light-weight technology of the heavy oil.
Description
The invention belongs to the catalyzer that refining of petroleum technology is used, be specially adapted to dreg-oil suspension bed hydrogenation cracking technology.
In recent years, China and other developed country just develop a kind of new petroleum residual oil hydroconversion process--dreg-oil suspension bed hydrogenation cracking technology in active research, this Technology is in the presence of the catalyzer of high dispersive type, cracking-residuum under the high temperature and high pressure condition, under higher air speed, the transformation efficiency of a through type operation can reach 70～90%.Present this technology has been developed ten broad varietys, the catalyzer that is adopted also has nothing in common with each other, natural mineral is arranged, the metal coal dust of carrying is arranged, oil soluble metal is arranged, brown coal fine powder etc. is arranged, but there is certain defective in existing technological process, if any the technological process reaction pressure very high, the catalyzer cost costliness that has, the bottoms conversion that has is not high, cost and process cost are higher, does not have competitive power economically.
The objective of the invention is to develop a kind of catalyzer of dreg-oil suspension bed hydrogenation cracking cheaply, also will keep residual oil that higher transformation efficiency is arranged simultaneously.
The object of the present invention is achieved like this, it is that mixing solutions thin up by nickelous nitrate, manganous nitrate, iron nitrate, Xiao Suangu forms, in the mixed solution of these four kinds of nitrate, the ratio of each component is: nickelous nitrate 50～80%, manganous nitrate 10～30%, iron nitrate 4～20%, Xiao Suangu 0.5～5%, aforementioned proportion is meant weight percent.The pH value of the mixed aqueous solution of above-mentioned four kinds of nitrate is not more than 3.
Hydrogenation of residual oil suspended bed catalyzer of the present invention, adopting nickelous nitrate, manganous nitrate, iron nitrate and Xiao Suangu is main component, raw material is easy to get, obtain conveniently, making the catalyzer cost reduces greatly, the catalyzer of hydrogenation and cracking activity and other type is suitable, and the process cost of the suspension bed hydrogenation process of handling viscous crude, residual oil is reduced greatly.
Further specify composition of the present invention below in conjunction with embodiment.
Obtaining of nitrate can be adopted following method, get metallic nickel, manganese, iron, cobalt respectively with nitric acid reaction, obtain corresponding nitrate, i.e. nickelous nitrate, manganous nitrate, iron nitrate, Xiao Suangu (also can adopt other method to obtain nitrate).Get nickelous nitrate 70 grams respectively, manganous nitrate 15 grams, iron nitrate 13 grams and Xiao Suangu 2 gram intermingling, make mixing solutions, thin up to pH value is not more than 3 catalyzer that promptly become dreg-oil suspension bed hydrogenation cracking again, join then and carry out emulsification and sulfuration in the raw material residual oil, the residual oil that contains catalyzer after the emulsification just can be used as the raw material of floating bed hydrocracking.
Above-mentioned catalyzer is used for dreg-oil suspension bed hydrogenation cracking technology, its running cost reduces greatly, make this technology have very strong competitive power, this is for a large amount of viscous crude processing of exploitation China, increase intermediate oil and yield of light oil, improve oil quality, the intensifier flexibility of operation, the industry of development heavy oil upgrading particularly develops heavy oil lighting technology and is of great practical significance and remarkable economic efficiency.
