This work focuses on the techno-economic analysis of alternative routes for the production of p-xylene from 5-hydroxymethyfurfural (HMF), which is a biomass derived platform chemical. P-xylene is a key intermediate in the production of terepthalic acid, which can be polymerized to polyester polyethylene terephthalate (PET). PET is a polymer resin widely used in the synthesis of fibers and beverage containers. Currently, p-xylene is primarily made from petroleum-based feedstocks. However, depleting oil resources and rising prices motivates the development of routes for the efficient synthesis of fuels and chemicals from renewable sources [1]. 5-hydroxymethyfurfural (HMF), which is considered as one of the ten most promising biomass-derived chemicals [2], can be used as a raw material for p-xylene synthesis [3-6]. The conversion of HMF to p-xylene can be carried out in two steps: from HMF to 2,5-dimethylfuran (DMF) and from DMF to p-xylene. First, HMF hydrodeoxygenation can form DMF using either hydrogen [5] or formic acid as an alternative hydrogen source [6]. Then DMF can react with ethylene [3, 7] or acrolein [4], followed by a dehydration reaction, to convert p-xylene. Each route has advantages and disadvantages in terms of use of renewable feedstocks, raw materials and utility costs. The aims of this work are to propose alternative flowsheets, to evaluate the economics of the production, to determine the major contributors of the total cost, and to explore and identify potential approaches to reduce these costs.

The analysis was carried out in two stages. In the first stage, an approximate evaluation of the various alternatives is performed considering different separation methods and rough estimates of the various parameters needed, whereas at the second stage a detailed economic estimation of the most promising path is performed. It is found that conversion and selectivity, the values of which were taken from the literature [5, 7], are the most important parameters that affect recycling streams and separations; and consequently the process economics. Finally sensitivity analysis was used to examine the impact of different factors on economics and to identify the most significant catalyst, material or reactor properties, and the improvement of which will have the maximum impact on process economics.

The basic models and different flowsheets were studied using ASPEN Plus [8]. ASPEN Economic Analyzer [9] was also utilized to determine the production cost of p-xylene, considering the raw material costs of HMF, H2, and ethylene [10, 11]. The main findings of this work contain the minimum selling cost of bio-based p-xylene, the impacts of different factors on the total cost and potential development to improve the economics of the conversion process.
