  • Publication number: 20210001308
    Abstract: The invention relates to a method for synthesizing silicoaluminophosphate sorbents such as SAPO-56 and SAPO-47 comprising the use of a specific structure directing agent (SDA) comprising a mixture of different types of amines The structure providing agent (SDA) comprises N,N,N?,N?-tetramethyl-1,6-hexanediamine (TMHD) and a co-structure providing agent (co-SDA) selected among primary, secondary and tertiary amines comprising up to 15 carbon atoms and mixtures thereof. A preferred SDA comprises isopropylamine, dibutylamine and tripropylamine The sorbents are particularly suitable for up-grading biogas such as separating carbon dioxide from methane.
