Efficient conversion of renewable biomass into value-added chemicals and biofuels is regarded as an alternative route to reduce our high dependence on fossil resources and the associated environmental issues. In this context, biomass-based furfural and levulinic acid (LA) platform chemicals are frequently utilized to synthesize various valuable chemicals and biofuels. In this review, the reaction mechanism and catalytic system developed for the generation of furfural and levulinic acid are summarized and compared. Special efforts are focused on the different catalytic systems for the synthesis of furfural and levulinic acid. The corresponding challenges and outlooks are also observed.

Forms Of Carbon

<p>The overutilization of fossil fuels will inevitably cause the global environmental problems and dwindling of available resources. For that reason, identifying renewable sustainable alternatives has attracted an increasing attention. Lignocellulosic biomass has been considered to be one of the most logical feedstock to replace traditional fossil resources as one of the most accessible renewable forms of carbon. One of the primary components of lignocellulosic biomass, next to hemicellulose and cellulose is lignin. It is a by-product in paper and pulp industry. Lignin is mainly used as fuel directly, without further utilization which is suggested to be a waste of natural resources. With this purpose, the valorization of lignin into value-added products needs particular attention of researchers. This review article focuses on chosen possible applications of lignin in chemical industry.</p>

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.
