# Analysis This is **not** a Victorian penny dreadful page—it is a scientific journal article. The page contains technical prose and a scientific graph discussing the catalytic oxidation of methane using metallized silica gels with different metal catalysts (platinum, palladium, copper). The text presents mathematical equations for calculating gas composition percentages after a chemical reaction, accompanied by "Rate-Conversion Curves" showing oxidation rates at various temperatures and gas flow rates.

CATALYTIC ACTIVITY OF METALLIZED SILICA GELS 1Q3 In the following reaction, CH, + .0. —>CO, + 2H.O if the fraction of methane oxidized is x, then the percent of methane in the gas mixture after the reaction is given by too (A — Ax) (1) mC 08% 2 Ax) Likewise the percent of O» in the final mixture is ie me Too (Og — 2Ax) (2) eA et OP — oAx) ) PLATINU so ba NE.) § ane eet em 27% Methane 70% Methane re Uh i A | 30% 0 15° ( QO S60 her * Rate of a in cc. per minute Eaa..I Rate-Conversion Curves for the Oxidation of Methane DO <a Cn A oS Percent CH, Oxidized The percent of CQO». in the gases after reaction is given by aif SES (3) (100 — 2Ax) where F = roof. It is evident that the amount of methane oxidized is equal to the amount of carbon dioixde formed. For the value of x we have rool _ (5) A + 2Af xX = Substituting the value of « from (4) in (1) and (2) we have A” = A+f (@A — 100) and Ola = O, + af (Og ven 100) The values of A” and Op.” given in the tables are calculated from the experi- mental value because f is determined experimentally. The value of O.’ was determined experimentally and the value of A’ was determined by difference. The values in the tables are expressed in percentage. (C(O) Aan ahoOo 6S (C(O)
