Catalytic properties of volcanic rocks in the synthesis of hydrocarbons from carbon monoxide and hydrogen
Results obtained from studying the catalytic properties of effusive rocks of various chemical compositions, extracted from lava flows of several Kamchatka volcanos, in the process of synthesis from carbon monoxide and hydrogen, are presented. It was evident that samples of volcanic rock display catalytic properties in the process of synthesis from CO and H/sub 2/ in which liquid and gaseous hydrocarbons and an insignificant amount of oxygen-containing compounds are formed as products of the reactions. At a synthesis temperature of 350/sup 0/C the catalytic activity of the samples is characterized by the conversion of CO at a level of 70 to 80%, and H/sub 2/ at 50 to 60%. The yield of oil, gasoline, and natural gas reached 40, 11, and 3 ml/m/sup 3/, respectively. The light synthetic products were presented based on saturated hydrocarbons of an aliphatic series with significant contents of olefins and insignificant quantities of alcohols and carbonyl compounds. The composition of gaseous products is characterized by significant unsaturation (approx. 33%) and a high content of butane-butylenic fractions (to approx. 55%). The data obtained showed that volcanic rocks were able to catalyze the synthesis of hydrocarbons from CO and H/sub 2/. The sources of the catalytic properties of the rocks shown are evidently iron compounds, and the remaining ingredients of the rocks are able to fulfill the role of structural or chemical promoters influencing the properties of the catalysts and the composition of the reaction products formed. 2 tables.
