Abstract
A kind of iron-manganese-zinc desulfurizing agent with excellent activity.This desulfurizing agent contains 10～40% (weight) manganese, 3～40% (weight) iron and 1～40% (weight) zinc and inert carrier, auxiliary agent and lubricant etc.Being suitable for middle organic sulfur of gaseous hydrocarbon (natural gas, casing-head gas and oven gas) and inorganic sulfur essence takes off.This desulfurizing agent has hydro-conversion organic sulfur and absorbing hydrogen sulphide dual-use function, and its cost is lower than cobaltmolybdate catalyst and the Zinc oxide desulfurizer with said function.Use this desulfurizing agent to replace the synthesis ammonia plant of traditional desulfurizing agent, can shorten flow process, reduction expense and easy and simple to handle.
Description
This patent is about the novel desulfurizing agent of a kind of iron-manganese-zinc.This desulfurizing agent has the dual-use function of hydro-conversion organic sulfur and absorbing hydrogen sulphide, and its cost is lower.This desulfurizing agent is suitable for the middle organic sulfur of gaseous hydrocarbon (natural gas, casing-head gas and oven gas) and the inorganic sulfur essence is taken off.
Along with hydro carbons is the development of raw material system synthetic ammonia and methyl alcohol technology, used various catalyst require more and more stricter to the sulfur content in the raw material hydrocarbon.Used Raney nickel in modernization ammonia factory and the methanol device, copper catalyst etc. require all that sulfur content is lower than 0.5ppm in the unstripped gas, are preferably lower than 0.2ppm.
For essence is taken off organic sulfur and inorganic sulfur in the light hydrocarbon, generally the method for Cai Yonging is that cobalt molybdenum catalytic hydrogenation transforms organic sulfur and zinc oxide absorbing hydrogen sulphide system, but these two kinds of desulfurizing agent costs are higher.
For many years, people attempt to seek always and a kind ofly transform all good cheap desulfurizing agent of assimilation effect, but do not see the report of commercial Application so far.
The purpose of this patent is to provide a kind of novel desulfurizing agent, and this desulfurizing agent has good conversion and absorbs dual-use function, be used at present gaseous hydrocarbon organic sulfur and inorganic sulfur remove have with low cost, easy and simple to handle to sulfide degree of purification height, advantages such as cost saving.
It is the difunctional desulfurizing agent of main active constituent with ferrimanganic zinc that this patent provides a series of.This desulfurizing agent mainly contains 10～40%(weight) manganese, 3～40%(weight) iron and 1～40%(weight) zinc.All the other are inert carrier, auxiliary agent and lubricant etc.
Example:
Prepare this patent desulfurizing agent A and B by the composition scope shown in the table 1.The sample of desulfurizing agent shown in the table 1 prepares with dry pigmentation under the industrial production condition.The oxide of iron and manganese mainly comes the natural minerals of self-contained manganese and iron, and zinc oxide from industrial zinc oxide and (or) zinc carbonate.At 300～500 milligrams of sulphur/rice of import organic sulfur content
3, hydrogeneous 2～5%(volume), pressure 1～30 kilograms per centimeter
2, 350～400 ℃ of temperature, air speed 1000～3000 hours
-1Test under the condition, the result is as shown in table 2.Desulfurization purifying degree represents to transform the absorption activity in the table 2, and Sulfur capacity is promptly represented service life.Operating cost is by containing 100 milligrams of sulphur/rice in the unstripped gas
3Calculate.
As can be seen from Table 2, desulfurizing agent A and B all can reach the desulfurized effect that the cobalt molybdenum adds zinc oxide.Novel desulfurizing agent A major advantage is inexpensive, but Sulfur capacity is low slightly.Desulfurizing agent B is a kind of modified of desulfurizing agent A, has kept the high activity advantage of A type, but Sulfur capacity is high far beyond A, thus under the same conditions service life longer, thereby make factory reduce the frequency of replacing desulfurizing agent.
Claims (2)
1, the novel desulfurizing agent of iron-manganese-zinc is characterized in that containing 10～40% (weight) manganese, 3～40% (weight) iron and 1～40% (weight) zinc and inert carrier, auxiliary agent and lubricant.
2, according to the desulfurizing agent of claim 1, the oxide of iron and manganese is mainly from the natural iron manganese mineral that contains with a fixed structure, zinc oxide then from industrial zinc oxide and (or) zinc carbonate.
