Ah&act

-A general model 1s presented for the descnpbon of successive gas-solid reactions occumng m a porous pellet Such reaction systems have begun attracting much attention mamly m the treatment of metal sulfides m the presence of luue The use of lime has been proposed as an alternative to the conventional processes which produce sulfur-contauung pollutants The model has been formulated m qmte generai terms such that specific details can easily be incorporated when It 1s apphed to an actual system The model enables us to predrct the rate of conversion and the extent of fixatrop of the mtermediate gas (sulfur-contammg gas) m the sohd &me) Other potenti apphcations of the model are dlscussed m the text 1 DITRODUCTION

Solventless reactions are currently a subject of extensive interest in both inorganic and organic chemistry. [1] In particular, organic synthesis may benefit from avoiding the use of organic solvents, yet this is valid only if a whole process, including work-up operations, is free from organic solve
