"In distinction to standard combustion, gasification applied sciences supply the potential of changing carbonatious fabric together with low or negative-value feedstocks, comparable to petroleum coke, and diverse waste material into usable strength assets or chemical feedstocks. With increasingly more businesses working and advertising and marketing structures in accordance with gasification innovations around the globe, this publication combines the latest

"Gasification applied sciences: A Primer for Engineers and Scientists discusses gasification strategies and some great benefits of every one know-how, together with gasoline clean-up applied sciences and people utilized in hybrid structures and gas cells. It additionally money owed for the first items which are recovered and explains how those items are purified and will be used as gas or for functions in petrochemical strategies. The e-book describes the stipulations during which optimum price intermediate items will be recovered, concentrating on key components corresponding to oxygen and air blown reactors, working temperature, inner and exterior heating, and reactor design.

The authors additionally identify how gasification can assist meet renewable strength ambitions, tackle issues approximately worldwide warming, and give a contribution to reaching Kyoto Protocol commitments." "Gasification applied sciences presents a multidimensional and well-rounded exam of present know-how, examine, functions, and improvement demanding situations for the large-scale commercialization of this more and more well known technology."--BOOK JACKET.

The Way of the Explorer: an Apollo astronaut's journey through the material and mystical worlds

Apollo 14 astronaut Mitchell deals a imaginative and prescient within which know-how and instinct are harmonized in pursuit of a extra complicated awareness. while Mitchell used to be hurtling again to earth after strolling at the moon in 1971, he had a profound experience that every one issues are interconnected and that the universe is an clever strategy with which we have to hyperlink up.

Draw the Lightning Down: Benjamin Franklin and Electrical Technology in the Age of Enlightenment

Such a lot folks know--at least we have heard--that Benjamin Franklin carried out a few form of electric scan with a kite. What few people realize--and what this ebook makes powerfully clear--is that Franklin performed an incredible function in laying the principles of contemporary electric technological know-how and know-how. This fast moving booklet, wealthy with old info and anecdotes, brings to lifestyles Franklin, the massive overseas community of scientists and inventors within which he performed a key position, and their striking innovations.

Practically, it is difficult to accurately measure particle temperature and mass as a function of time, flow, or composition of volatiles in a fluidized bed. However, there is general agreement among researchers that biomass compared to coal is more volatile, the biomass gasification process occurs under less severe conditions compared to coal gasification processes, and the char resulting from pyrolysis of biomass is more reactive than pyrolytic coal char. The kinetics of gasification, particularly gasification of carbonaceous solids, is still the subject of intensive investigations and discussions; and existing gasification kinetics models are of limited value in designing commercial gasification reactors.
