The inventive concepts disclosed and/or claimed herein relate generally to catalysts and, more particularly, but not by way of limitation, to a heterogeneous, metal-free hydrogenation catalyst containing frustrated Lewis pairs. In one non-limiting embodiment, the heterogeneous, metal-free catalyst comprises hexagonal boron nitride ( h -BN) having frustrated Lewis pairs therein.

A renewable biofuel is based on a highly efficient batch catalysis methodology for conversion of 1-butene to a new class of potential jet fuel blends. By tuning the catalyst and then using the dimer produced, the carbon use can be about 95% or greater. This is particularly useful where the source of raw materials (i.e., biomass/biofeedstock) is limited. The batch catalysis approach disclosed requires a minimal input of energy and hydrogen to make fuels that possess useful flash points, coldflow properties, and solution density/energy content. This new process affords a saturated hydrocarbon fuel that has a high solution density and thus possesses a higher calculated power density (per volume) than similar fuels made by the GTL Fischer-Tropsch processes.
摘要:
Integrated isomerization and ionic liquid catalyzed alkylation processes may comprise integrating ionic liquid alkylation and n-butane isomerization using a common distillation unit for separating an n-butane containing fraction from at least one of an alkylation hydrocarbon phase from an ionic liquid alkylation reactor and an isomerization hydrocarbon stream from an isomerization unit. The n-butane containing fraction may undergo isomerization to provide an isomerization reactor effluent comprising the isomerization hydrocarbon stream. An isobutane containing fraction, separated from at least one of the alkylation hydrocarbon phase and the isomerization hydrocarbon stream, may be recycled from the distillation unit to the ionic liquid alkylation reactor.
摘要:
Novel silicoaluminophosphate molecular sieve compositions comprising SAPO-11 and SAPO-41 with at least about 5 wt% of in s/Yw-produced amorphous portion. Such compositions can be uncalcined or calcined and novel processes for their preparation are described. These compositions, when loaded or impregnated with a catalytically active species such as a Group VIII noble metal are novel, and are excellent hydroisomerization catalysts.
