Research On Heat Changing Law Of Photosynthetic Bacteria Continuous Hydrogen Production Process

With the energy crisis, the hydrogen advantages highlight, photosyntheticbacteria metabolic hydrogen production has been more and more be scientific researchworkers take seriously. Biological qualitative solar photosynthetic biological hydrogentechnology has important scientific significance. Photosynthetic bacteria metabolichydrogen existing in the process of a lot of heat change has become photosyntheticbiological hydrogen production system in an important basic problem. Photosyntheticbacteria metabolic process of hydrogen system produces a certain quantity of heat. Heat canlead not only to the reactor produce temperature stress deformation, more will affectresponse enzyme activity, influence photosynthetic bio-hydrogen system of energyconsumption, change the photosynthetic bacteria produce hydrogen and physiologicalactivities of living conditions, thus affecting metabolism of photosynthetic bacteria in theprocess of hydrogen production hydrogen content in and hydrogen rate and so on manykinds of factors. So, photosynthesis bacteria produce hydrogen system heat effect in thestudy is very important.This paper carried on the different kinds of raw materials for the production of hydrogenmatrix and different particle size the ultrastructure of corn straw for hydrogen productionmatrix, and the corn straw were in different reaction conditions such as pH value,temperature, light intensity, different reactor in conditions such as location, temperature inthe light material liquid hydrogen process with the reaction time and spatial change ofexperiments. Analyzed the various conditions in photosynthetic light material liquidhydrogen in different locations of the reactor temperature distribution and the changing laws,and light photosynthetic hydrogen initial temperature stage and reaction of the steady phasechange material liquid temperature on regression analysis. The experimental results forfurther development of the biological fiber in photosynthetic straw in the application ofhydrogen reaction provides important reference basis.Through this paper the research, the conclusions are as follows:(1) Through the research of different raw materials, different particle size corn strawmaterial liquid hydrogen reactor in light different position, under different conditionsand the temperature distribution and change rule found that the yield of hydrogen in different conditions in the system and the system as a whole different positions intemperature with hydrogen the extension of time both had obvious change, namelyphotosynthetic bio-hydrogen process system are different range of temperature rise.(2) From the single factor experiment indicated that the hydrogen production base of thespecies, particle size, light intensity, pH value factors such as the yield of hydrogenlight hydrogen content system changes in temperature have certain effect, from thetemperature variation of influence look, light hydrogen in use process more small,light particles relatively strong in2000lux~2500lux, pH value neutral is relativelyappropriate. Although the yield of hydrogen glucose obvious effect is good, but badfor a large-scale promotion, the poor in economy. But corn straw relative to thesorghum straw, in hydrogen process effect is appropriately applied to thepopularization and application of the future.(3) As a hydrogen production base of the species, particle size, light intensity, pH valuefactors such as the yield of hydrogen light hydrogen content system is consistent withthe temperature change. Generally speaking, the temperature change is larger, thehydrogen production quantity.(4) From the system at different sites in the determination of value and change with thereaction time change trend, the light that photosynthetic hydrogen within reactortemperature field distributions for: The reactor temperature at the bottom of the centeris higher than the reactor in the upper, temperature, but the difference in value is notmuch; The reactor wall temperature higher than internal temperature of the reactor, thedifference is the difference in value between internal slightly big. In500mL lightphotosynthetic hydrogen reactor temperature distribution is evener, maximumtemperature difference is0.3℃, andthe rules the temperatures change is consistent.The outside light source in the process of production of hydrogen hydrogen effect hasplayed a very important role. In the actual application, liquid materials should bemanaged to keep the photosynthetic bacteria produce hydrogen in normal work, fullyaccept illumination, further improve the yield of hydrogen production processphotosynthesis hydrogen effect.
