Abstract
Natural gas mixture containing suspended tarry particles and water as contaminants are purified by systems providing upward passage of such contaminated gas mixtures through interparticulate spaces in a vertically extending stable filter bed composed of hard lapilli-sized solid masses having internal vesicles connected to peripheral surfaces characterized by peripherally open glassy surfaced vesicles, said masses partially immersed in a volume of methyl alcohol.
