“…All process chains were composed from PCUs and compared: PC 1 (see Figure , TOP), which consists of the PCU sequence: algae farming in open pond photobioreactors with injection of sequestrated CO 2 or concentrated flue gas (A), algae processing to extract glycerol and algae oil (B and C), transesterification to biodiesel (D), − conversion of glycerol to methanol (GtM process, E), ,− conversion of methanol to propylene (Mobil process, MtP, F), , propylene based acrylonitrile synthesis (Sohio process, G), − and polymerization of acrylonitrile to polyacrylonitrile and its fiber (Dralon process, H) . Possible variations of PC 1 are 1b, 1d with energetic utilization of biodiesel by means of combined heat and power (CHP) plants, and 1c, 1d with internal coverage of the methanol demand of D by means of partial back feed from E. PC 2 (see figure S3 in the Supporting Information (SI)) is characterized by the “shortcut” of directly converting glycerol to acrylonitrile (GtAN) .…”

Carbon capture and sustainable utilization (CCU) is essential to accomplishing the targets of 2015's Paris Agreement. A promising option consists of algal based CO 2 conversion into lipid rich biomass with further processing into polyacrylonitrile (PAN) fiber, the major precursor for carbon fiber production. A first feasibility analysis was carried out under multiple constraints for price, byproduct yield, and consumption of land, CO 2 , and energy. Several process-route alternatives were composed, modeled, and compared in terms of mass and energy flows, resource needs, and cost. To quantify risks from market and modeling uncertainties, we conducted a primary techno-economic analysis (TEA) with variable process pathways in a dynamic economic model of a related project company (SPV), embedded in a Monte Carlo simulation. First results indicate that process combinations with algal biodiesel-production and biomass-liquefaction (BtL) components come close to meeting the multiple constraints and justify progressing to extended research and development activities.

“…The most ideal syngas for the synthesis of methanol has a stoichiometric number ( S N ) of 2 (see Eq. 12), which corresponds to the stoichiometric ratio for the synthesis of methanol [2]. All the reactants react to generate methanol when S N is equal to 2, only CO and CO 2 react when S N is higher than 2, and hydrogen is the limiting reagent when S N is less than 2 [50,53].…”

“…As a result, new technologies must be developed, or existing technologies must be improved to focus on the use of renewable and sustainable energy resources. These new or enhanced technologies must be ecologically beneficial and capable of replacing non-renewable resources [2,3]. From 2008 through 2035, global energy-linked CO 2 emission is predicted to increase by 43% if petroleum-based resources are used [4].…”

Due to the large amount of crude glycerol produced as a by-product by the biodiesel industry, alternative technologies for converting glycerol to value-added fuels such as syngas have been proposed. By employing four main processes, the syngas could further be used to produce methanol. The first process is steam reforming (STR) where the crude glycerol is converted into syngas. The next step is a three-unit pressure swing adsorption (PSA) system which is employed to condition the syngas into the required stoichiometric ratio. The final two process are the methanol synthesis and methanol purification processes. The effects of STR temperature, steam-to-glycerol ratio (SGR), methanol synthesis temperature and pressure were all investigated. The results obtained shows that 0.29 kgMeOH/kgCG can be obtained through this process at STR of 650 ℃, SGR of 9, and methanol synthesis temperature and pressure of 250 ℃ and 80 bar respectively. In addition, a methanol production plant capacity of 6.8 tonnes/hr of crude glycerol feed for a 20-year plant life was investigated. The result from the economic analysis carried out shows that production of methanol from glycerol is economically feasible with net present value (NPV), return on investment, (ROI), discounted payback period (DPBP) and net production cost (NPC) of $74.2 million, 17%, 4.59 years, and 85₵/kgMeOH respectively. The sensitivity analysis results show that the revenue from sales of methanol and byproducts (hydrogen and methane), the manufacturing cost, the cost of raw materials, as well as fixed capital investment (FCI) were the most sensitive economic parameters.

The properties and the applications of the main monocyclic aromatic hydrocarbons (benzene, toluene, ethylbenzene, styrene, and the three xylene isomers) and the industrial processes for their manufacture from fossil raw materials are summarized. Potential ways for their production from renewable sources with thermo-catalytic processes are described and discussed in detail. The perspectives of the future industrial organic chemistry in relation to the production of high-octane bio-gasolines and monocyclic aromatic hydrocarbons as renewable chemical intermediates are discussed.
