摘要： Systems and methods are provided for integrated conversion of biomass to ultimately form naphtha and/or diesel boiling range products. The integrated conversion can include an initial conversion of biomass to alcohols, such as by fermentation, followed by conversion of alcohols to olefins and then olefins to naphtha, jet, and diesel boiling range compounds, with high selectivity for formation of diesel boiling range compounds. The integrated conversion process can be facilitated by using a common catalyst for both the conversion of alcohols to olefins and the conversion of olefins to naphtha and/or diesel boiling range compounds. For example, ZSM- 48 (an MRE zeotype framework structure catalyst) can be used as the catalyst for both conversion of alcohols to olefins and for oligomerization of olefins with increased selectivity for formation of diesel boiling range products.

摘要： Many linear alpha olefin (LAO) syntheses form a range of LAO products when oligomerizing ethylene in the presence of a Ziegler-type catalyst. The range of products typically requires a plurality of distillation columns to separate the LAO products up to a desired carbon count, but such approaches may be energy- and capital-intensive. LAO product separation using at least one dividing wall column may lessen these burdens. Methods for separating LAOs may comprise: providing a pre-processed product stream comprising Cg+ linear alpha olefins (LAOs) to a first of a series of distillation columns, at least one member of the series of distillation columns comprising a dividing wall column; and separating an overhead stream comprising a first LAO from the dividing wall column and one or more side streams from the dividing wall column, each side stream comprising a different LAO that also differs from the first LAO.

摘要： Systems and methods of dehydrogenating a hydrocarbon in a fixed bed dehydrogenation unit. A method for dehydrogenating a hydrocarbon is applied to a fixed bed reactor. The hydrocarbon flows to a fixed bed reactor to be dehydrogenated in presence of a catalyst in the fixed bed reactor. The catalyst in the fixed bed reactor is then regenerated. The period for dehydrogenation, the period for catalyst regeneration and the period for total slack time are controlled such that total slack time is less than both half of the period for dehydrogenation and half of the period for regeneration. One of the advantages of the process comes from optimization of the slack time, thereby increasing the catalyst utilization rate and number of reactors concurrently online.
