Abstract
A tin-containing composition is provided, the composition having a tin Auger line transition wherein the ratio of the area of the M.sub.5 N.sub.4,5 N.sub.4,5 transition peak at 424.5 eV.+-.leV, having a 6 eV FWHM, to the area of M.sub.4 N.sub.4,5 N.sub.4,5 transition peak at 430.5 eV.+-.1eV is at least 10 to 1. Additional such tin-containing compositions, including catalyst compositions are also provided as are methods for converting feedstock alkanes containing from 1 to 4 carbon atoms to higher molecular weight hydrocarbons using such catalyst compositions.
