But in 1875, a contact-process acid plant was started up at Freiberg in Germany, using lead-chamber sulfuric acid decomposed by heat as a source for pure sulfur dioxide From the mid-1880s on, the output of acid produced by the contact process grew rapidly By then, gases from pyrites had replaced sulfuric acid as a source of sulfur dioxide...

The lead chamber process was an industrial method used to produce sulfuric acid in large quantiti It has been largely supplanted by the contact process In 1746 in Birmingham, England, John Roebuck began producing sulfuric acid in lead-lined chambers, which were stronger and less expensive, and could be made much larger, than the glass containers which had been used previously...
Apr 26, 2017 0183 32 The development of the less expensive and less easily contaminated vanadium pentoxide V 2 O 5 catalyst by BASF in Gemany in 1915, combined with increasing demand for concentrated sulfuric acid by the chemical industry, has led to the gradual replacement of the lead-chamber process by the contact process In 1930, sulfuric acid produced by the ....
The raw materials used to make sulfuric acid are elemental sulfur, H 2 SO 4 and H 2 S Till 1970, Ion Pyrites and related compounds were the predominant raw materials The large amount of sulfuric acid also produced as a by-product of non-ferrous metal smelting ie roasting sulfide ores of copper, lead, molybdenum, nickel, zinc and some others...
There are two major processes lead chamber and contact for production of sulfuric acid, and it is available commercially in a number of grades and concentrations The lead chamber process, the older of the two processes, is used to produce much of...
In non-discretionary production, sulfur or sulfuric acid is recovered as an involuntary by-product, the quantity of which is subject to the demand for the primary product alone The lead chamber process has now been almost completely superseded by the contact process in the industrial production of sulfuric ac...

In 1746, John Roebuck established the lead chamber process, in which sulphur was mixed with saltpetre potassium nitrate and a catalyst, and then burnt inside a lead chamber The sulphur dioxide produced was dissolved in water on the floor of the chamber, lead metal being used because it does not react with the resulting sulphuric ac...
The contact process is the current method of producing sulfuric acid in the high concentrations needed for industrial process Platinum used to be the catalyst for this reaction however, as it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium V oxide V 2 O 5 is now preferred This process was patented in 1831 by British vinegar merchant Peregrine Phillips...
