Wide Applicability

In this study, the optimization of four processing schemes were developed for the production of 5 hydroxymethylfurfural (HMF), a chemical platform compound obtained from lignocellulosic biomass and used to make the connection with products from fossil resources. Despite its wide applicability, problems associated with its synthesis hindered its greater use. In this scenario the use of a computer program stands out, as the optimization of processes can be used, evaluating the factors and finding parameters that minimize the costs associated with its production. The optimization of these systems was made from the minimization of the total annual cost of the process carried out through the  Aspen Plus® v.11 software, in addition, the economic feasibility of the process was analyzed and it was possible to obtain the HMF at 1.00$ .kg-1 and the co-product levulinic acid between 1.92 and 3.08 $.kg-1. It was also possible to note that among the operating costs, those from glucose had the greatest effect on its value, whereas in relation to equipment costs, reactors and distillation columns were the ones that had the greatest influence.

Lipid Yield

Today one of the most interesting ways to produce biodiesel is based on the use of oleaginous microorganisms, which can accumulate microbial oil with a composition similar to vegetable oils. In this paper, we present a thermo-chemical numerical model of the yeast biodiesel production process, considering cardoon stalks as raw material. The simulation is performed subdividing the process into the following sections: steam explosion pre-treatment, enzymatic hydrolysis, lipid production, lipid extraction, and alkali-catalyzed transesterification. Numerical results show that 406.4 t of biodiesel can be produced starting from 10,000 t of lignocellulosic biomass. An economic analysis indicates a biodiesel production cost of 12.8 USD/kg, thus suggesting the need to increase the capacity plant and the lipid yield to make the project economically attractive. In this regard, a sensitivity analysis is also performed considering an ideal lipid yield of 22% and 100,000 t of lignocellulosic biomass. The biodiesel production costs related to these new scenarios are 7.88 and 5.91 USD/kg, respectively. The large capacity plant combined with a great lipid yield in the fermentation stage shows a biodiesel production cost of 3.63 USD/kg making the product competitive on the current market of biofuels by microbial oil.
