A　low-cost　and　process-intensified　synthesis　approach　of　SSZ-35　zeolite　via　a　seed-assisted　method　is　presented.　This　approach　involves　the　development　of　a　relatively　inexpensive　template　and　the　application　of　seeds　to　minimize　crystallization　time　and　template　consumption.　Herein,　N-Ethyl,　N-methyl　2,6-cis-dimethylpiperidinium　hydroxide　(EMDMPOH)　is　selected　as　a　template　to　synthesize　SSZ-35　zeolite,　and　a　simplified　and　optimized　scheme　for　the　preparation　of　such　a　template　is　proposed.　Specially,　the　high-purity　EMDMPOH　is　prepared　by　a　sequential　alkylation　of　2,6-dimethylpiperidine　with　iodoethane　and　iodomethane,　followed　by　ion　exchange.　By　employing　a　seed-assisted　strategy,　the　synthesis　process　of　SSZ-35　zeolite　is　intensified,　resulting　in　a　significant　reduction　in　crystallization　time　from　7　d　to　75　h.　Systematic　characterizations　reveal　that　the　synthesized　SSZ-35　zeolite　has　smaller　crystals　and　larger　specific　surface　area　in　comparison　with　the　reference　sample,　leading　to　enhanced　selectivity　in　n-octane　hydroisomerization.　Moreover,　the　cost　accounting　analysis　shows　a　notable　decrease　in　the　synthesis　cost　of　SSZ-35　zeolite　by　using　the　synthesis　route　that　combines　the　simplified　process　for　preparing　the　template　and　the　reduced　amount　of　template.　©　2024
