Foamable molding compositions
This patent describes a process for the preparation of hydrocarbons from synthesis gas comprising hydrogen and carbon monoxide, with a reduction in the production of durene which comprises contacting the synthesis gas, at hydrocarbon synthesis conditions, with a catalyst composition. The composition comprises: at lease one metal or compound of metal from Group 2b and at least one metal or compound of metal from Grouop 6b of the Periodic Table of Elements and a crystalline aluminum silicate crystallized from an aqueous alkaline crystallization mixture comprising at lease one silicon compound comprising SiO/sub 2/, at lease one aluminum compound comprising Al/sub 2/C/sub 3/, at least one compound of a metal selected from Group 1a (MX) of the Periodic Table of Elements wherein MX represents at least one M/sub n/Z and at least one MOH in which M represents an alkali metal ion, Z represents an anion of a mineral acid and n satisfies the electroneutrality of the compound M/sub n/Z and organic nitrogen compounds comprising pyridine or a compound of pyridine represented by the formula (RN) wherein RN is selected from the group consisting of pyridine, alkyl pyridine, alkyl substituted pyridimes and amino pyridimes and wherein the alkyl groups comprise from one to four carbon atoms and an organic quaternary ammonium compound represented by the formula R/sub 4/NY wherein in R/sub 4/NY the R groups comprise four of the same or different groups having from one to twenty carbon atoms selected from alkyl groups, substituted alkyl groups or combinations thereof, wherein the substituents on the alkyl groups are hydroxy and/or halogen, and Y represents an anion of a mineral acid or hydroxyl ion, in the following mole ratios: RN:R/sub 4/NY=1-1000 SiO/sub 2/:R/sub 4/NY=10-5000 SiO/sub 2/:Al/sub 2/O/sub 3/=50-300 SiO/sub 2/:MX<15 and H/sub 2/O:SiO/sub 2/=5-100.
