In a thermochemical circulation process, hydrogen and oxygen are obtained from water wherein sulfuric acid and the paraffin hydrocarbon corresponding to the olefin used are formed from water, sulfur dioxide and a low-molecular weight olefin, particularly ethylene; the sulfuric acid is decomposed into ...
Producing hydrogen from water always generates oxygen. A typical alkaline electrolyzer has a positive andnegative electrodepaired up inside a chamber of alkaline water, separated by an ion-permeable barrier. When anelectric currentis applied, water reacts at the cathode by forming hydrogen and negativ...
Reforming is the most widespread method for producing hydrogen from natural gas. There are three methods: steam reforming (using water as an oxidant and a source of hydrogen), partial oxidation (using oxygen in the air as the oxidant), or a combination of both called autothermal reforming (ATR...

根据画线 前的“Hydrogen may be a'clean'fuel"可知,氢气可能是一种 “清洁”的燃料;再结合画线词前的but可知, 此处内容与前面的内容构成转折关系,故此处 指但用化石燃料制造的氢气就不那么清洁了。 it指代氢气。 2.B 细节 解题。 根据第三段中的“Energy experts give hydrogen different names depending on...
Formation of sulfuric acid and sulfur trioxide/water complex from photooxidation of hydrogen sulfide in solid oxygen at 15 K The photooxidation of H2S in solid O2 at 15 K by UV light (λ < 300 nm) gives H2O, SO2, SO3, and H2SO4 as stable products which are identified by FTIR spectrosc...
SUBSTANCE: new method was used for producing electrolytic hydrogen and oxygen and deionizing supply water. Disclosed method included steps of electrolytically decomposing alkaline solution under pressure, catalytically purifying resultant oxygen and hydrogen, and subsequently refining these gases. One of the...
