After decades of development, the steam explosion technology has made greatprogressMost research still uses chemicals to pretreat biomass feedstocks at homeand abroadBased on the differences in the chemical composition and structure ofstraw and wood, author proposed the low pressure and unpolluted steam explosiontechnology of straw without any chemicals additionAnd then the new low pressureand unpolluted steam explosion technology is extended to tobacco processing,herbal extracts, cleaning degumming of hemp fiber, etc.Steam explosion technology is considered as one of the most cost-effectivepretreatments of biomassSteam explosion is the process in which the solid materialespecially lignocellulosic feedstock is pretreated with saturated steam orhigh-pressure gas for a certain time, and the solid material is then instantaneouslyexplodedIn 1928, W.HMason from USA invented firstly the steam explosiontechnology, which only used 7–8 MPa saturated steam as a medium steamThissteam explosion technology was used only for the research of fiberboard preparation.Due to high pressure, this steam explosion technology is difficult to be applied.However, from the beginning of the 1980s, the steam explosion technology hasattracted more attention again.

On the basis of steam explosion, author extended the explosion media from thetraditional steam to mix media, and developed inert medium steam explosiontechnology and mixed media steam explosion chnologySteam explosion technologyhas been used to the gradient temperature steam explosion process and other low-temperature steam explosion process of herbal treatmentA series of clean,efficient, and economical combinatorial pretreatment technologies taking steamexplosion as the core have been invented, by which a clean and efficient separationof biomass components is achievedExplosion technology is no longer limited to asingle steam explosionThe media of explosion technology have been upgraded tomulti-gas medium based on the requirements of processBecause the steam explosion media have been developed to a variety of gaseous medium, the steam explosion is named gas phase explosion in order to enrich and enhance the connotationof traditional steam explosion technologyCurrently, gas explosiontechnology is mainly applied for lignocellulosic feedstock, whose common aim wasto achieve a multi-component separation and utilization, namely biomass refining.
In 2006, we published the first monograph about the introduction of steamexplosion technologyBased on our research of gas explosion technology andacademic exchange with domestic and foreign peer in recent decades, authors writethis book—Gas Explosion Technology and Biomass RefiningAuthors hope to throw out a minnow to catch a whale and promote the better development of gas explosion technology.
This book analyzes the principle of gas explosion technology and the separationmechanism of solid material multi-component, and introduces gas explosionequipment and processAdditionally, the application process of biomass refining isdescribed systematicallyThis work was financially supported by the National Basic Research Program of China (973 Project), the National High Technology Research and Development Program of China (863 Program), and the Knowledge Innovation Program of the Chinese Academy of SciencesIn addition, the works of my doctors and masters were essential preconditions for publishing this bookIn
