“…Powder kinetics. Some of the most commonly used kinetic models for methanol synthesis are the models provided by Graaf 13,[34][35][36][37] and Vanden Bussche and Froment. 15,[38][39][40][41] Graaf's kinetic model is based on the stepwise hydration of CO and CO 2 with the rate determining step (rds) determined by an error discussion of the 48 possible combinations of rds of COhydrogenation, CO 2 -hydrogenation and reverse WGS (rWGS).…”

“…After purifying the biogas, methane underwent an oxidation process in order to obtain synthesis gas, and catalytic reform was employed to obtain methanol [122,123]. The proposal to use biogas to produce methanol is a way to obtain alcohol from a renewable source, since the methanol produced in the current context is predominantly from natural gas of fossil origin [124,125]. And, the methanol produced by this route can be returned to the biodiesel production process plant and for use as one of the reagents [62,126].…”

Biodiesel is seen as a successor to diesel of petrochemical origin, as it can be used in cycle and stationary engines and be obtained from renewable raw materials. Currently, the biodiesel production process on an industrial scale is mostly carried out through the transesterification reaction, also forming glycerol as a product. Pure glycerol is used in the pharmaceutical, cosmetic, cleaning, food, and other industries. Even presenting numerous applications, studies indicate that there is a saturation of glycerol in the market, which is directly related to the production of biodiesel. This increase causes a commercial devaluation of pure glycerol, making separation and purification processes unfeasible from an economic point of view. Despite the economic unfeasibility of the aforementioned processes, they continue to be carried out due to environmental issues. Faced with the problem presented, this work provides a bibliographical review of works that aimed to use glycerol as a raw material for the production of biofuels, with these processes being carried out mostly via fermentation.

The recent revolution in shale gas has presented opportunities for distributed manufacturing of key commodity chemicals, such as methanol, from methane. However, the conventional methane‐to‐methanol process is energy intensive which negatively affects the profitability and sustainability. We report an intensified process configuration that is both economically attractive and environmentally sustainable. This flowsheet is systematically discovered using the building block‐based representation and optimization methodology. The new process configuration utilizes membrane‐assisted reactive separations and can have as much as 190% higher total annual profit compared to a conventional configuration. Additionally, it has 57% less CO2‐equivalent greenhouse gas emission. Such drastic improvement highlights the advantages of building block‐based computer‐aided process intensification method.
