New solid superacidic nano-catalysts have been recently developed in our Industrial Catalysis laboratory, Concordia University, by successfully encapsulating a liquid superacidic species, triflic acid, into a solid nano-sized matrix called silica nanoboxes.The present project whose funding is applied to NSERC, comprises two sections:a) Preparation of nano-structured catalysts by encapsulation of strong acidic or superacidic species into Al- and Si-nanoboxes, or introduction of metal or metal oxides into the same nanoboxes, or preparation of new bifunctional and hybrid catalysts in which these nanoboxes are the main catalyst components.b) Application of these nano-catalysts to three catalytic reactions of industrial interest:1) Production of bio-fuels (bio-diesels) and bio-additives to fuels from biomass: alkyl levulinates (ethyl and methyl levulinates) from cellulosic wastes (paper milling sludges, agricultural/forestry residues, wood residues).2) Ethylene and alkyl benzene from bio-ethanol.3) Preparation of novel nano-catalysts for the Thermocatalytic Cracking (TCC) for the production of ethylene and propylene, two important intermediates for plastics, synthetic fibers and other large-volume products for the petrochemical industry.

我们康考迪亚大学工业催化实验室最近开发了新型固体超酸纳米催化剂，成功地将液体超酸物质三氟甲磺酸封装到称为二氧化硅纳米盒的固体纳米尺寸基质中。本项目的资金应用于 NSERC，包括两个部分：a）通过封装强酸制备纳米结构催化剂 将金属或金属氧化物引入到铝和硅纳米盒中，或将金属或金属氧化物引入到相同的纳米盒中，或制备以这些纳米盒为主要催化剂成分的新型双功能和混合催化剂。b）这些纳米催化剂在三种具有工业意义的催化反应中的应用：1）生物燃料（生物柴油）的生产和 来自生物质的燃料生物添加剂：来自纤维素废物（造纸污泥、农业/林业残留物、木材残留物）的乙酰丙酸烷基酯（乙酰丙酸乙酯和乙酰丙酸甲酯）。2）来自生物乙醇的乙烯和烷基苯。3）用于热催化裂化（TCC）生产的新型纳米催化剂的制备 乙烯和丙烯是塑料、合成纤维和其他石化工业大批量产品的两种重要中间体。
