In order to reach the foregoing invention purpose, the present invention adopts following solution:
A kind of controllable type hydrogen manufacturing additive mainly is a kind of starch pulvis that is made into according to a certain percentage by Magnesium Stearate (Magnesium Stearate), sodium-alginate (Sodium Alginate) and alginate calcium (Calcium Alginate).
Described controllable type hydrogen manufacturing additive is meant the additive of the method that is used for aluminium and alkaline inorganics (sodium hydroxide NaOH) mixing back hydrogen manufacturing.
Described Magnesium Stearate (Magnesium Stearate) and alginate calcium (Calcium Alginate) are fixed as respectively under the constant situation of 80wt% and 5wt% at aluminium and alkaline inorganics (sodium hydroxide NaOH) content, and each is that hydrogen output maximum and speed are the most stable with 7.5wt% as proportioning.
Beneficial effect of the present invention:

Embodiment
Below in conjunction with accompanying drawing the present invention is further described:
A kind of controllable type hydrogen manufacturing additive is actually a kind of speed of response suppressor factor.Hydrogen producing technology of the present invention is meant that adopting metallic aluminium (Al) powder to mix with alkaline inorganics (NaOH sodium hydroxide) produces hydrogen, and this hydrogen producing technology hydrogen output is big, and product hydrogen speed is fast.But in producing the hydrogen process, cause security incident easily simultaneously, also be not easy to the direct utilization of hydrogen owing to excessive velocities.At this moment add speed of response control agent of the present invention, the speed in the hydrogen process is produced in control, reaches stable and produces hydrogen, safety is produced hydrogen, makes whole product hydrogen process be in a safety, controlled state.This speed of response control agent mainly is that a kind of Magnesium Stearate Magnesium Stearate, sodium-alginate Sodium Alginate and alginate calcium Calcium Alginate etc. mix a kind of starchy material that produces, and it can make hydrogen produce according to stable speed within a certain period of time.
The present invention mixes on the technical foundation of producing hydrogen technological improvement in addition and a kind of speed of response suppressor factor of obtaining at metallic aluminium (Al) powder with alkaline inorganics (NaOH sodium hydroxide).What Fig. 1 described is the different design sketch that in producing the hydrogen process, adopts ordinary tap water to produce with zero(ppm) water respectively.As shown in Figure 1, under the condition that the aluminium amount equates, compare the amounts of hydrogen of using zero(ppm) water to carry out obtaining behind the chemical reaction with ordinary tap water and omit many.Can learn that with mass flow controller MFC (Mass Flow Controller) test zero(ppm) water gained amounts of hydrogen is high more about 0.2% than ordinary tap water gained amounts of hydrogen, and hydrogen output begins along with the increase of time growth gradually, reduce after for some time.When aluminium and acidity or basic soln reaction generated hydrogen, hydrogen is also a large amount of rapidly in the certain hour produced.If hydrogen is connected to polymer fuel cell, crosses senior general because of pressure and can't use.Need earlier using behind hydrogen storage to the gas-holder this moment.Big with the made equipment volume of this method, heavier and inconvenient the moving of weight.Use the method for the invention hydrogen manufacturing, aluminium powder is with Magnesium Stearate Magnesium Stearate that plays the disintegrating agent effect and sodium-alginate Sodium Alginate or react after as shown in Figure 2 mixing of Calcium Alginate alginate calcium.The pressure of hydrogen can not increase within a certain period of time, and hydrogen also can not produce in the short period of time in a large number.The object of the invention is that hydrogen can be stablized, continue to use.
The effect of the different proportionings of speed of response suppressor factor in the process of the present invention is described below; As shown in Figure 2; Aluminium and the NaOH sodium hydrate content is fixed as 80wt% respectively and 5wt% is constant; 3 kinds of disintegrating agent (speed of response suppressor factor) Magnesium Stearate Magnesium Stearate (I), sodium-alginate Sodium Alginate (II) and every kind of content 7.5wt% of alginate calcium Calcium Alginate (III) process the different disintegrating agents that 3 kinds of content are 15wt% after the combination in twos.Stablize like Fig. 3, hydrogen-producing speed shown in Figure 4.
Hydrogen sharply produces in the time (about 2-5 minute) that the proportioning of " 1-2 " among Fig. 2 is extremely lacked after beginning, and hydrogen-producing speed is more stable afterwards." 1-1 " and " 1-3 " produced hydrogen in 5-10 minute, " 1-2 " as shown in the figure compares steadily." 2-1 " compares with " 2-2 ", " 2-3 ", and hydrogen sharply produces during beginning, and to compare hydrogen output less with " 1-2 ".The proportioning that gas production rate is bigger in the time of can beginning to react thus is applicable to polymer fuel cell.Because link to each other with pipeline between hydrogen production bioreactor and the polymer fuel cell, air is arranged in the pipeline when just bringing into use, need this moment a large amount of hydrogen that air is released outside the pipeline, fast environment in the crossover connection.Draw thus, each is preferred plan of the present invention with 7.5wt% content when mixing for Magnesium Stearate Magnesium Stearate (I) and alginate calcium Calcium Alginate (III).
Though in addition in Fig. 2, do not list, aluminium and disintegrating agent (speed of response suppressor factor) also have multiple proportioning, and the product hydrogen meter of listed proportioning is existing best among Fig. 2.
So far whole invention end of processing.
