The Impact

A detailed economic evaluation was carried out to determine the impact of biomass and coal co-firing on power plant carbon capture by methods of plants equipment designing factors and performance, and the sum up of the associated breakdowns of CAPEX and OPEX. Based on the assumptions of the CO2 neutrality of biomass and likely governmental incentives to reduce CO2 emissions, the study results show that biomass and coal co-firing would result in both lower cost of carbon avoided (carbon capture) and lower incremental cost of electricity generation when MEA solvent carbon capture is applied. Two scenarios for co-firing with carbon capture, 30% biomass blending and 90% or 60% CO2 capture from stack, indicate different preference depending on lower or higher incentives.

Reaction In Water

The formation of keto-enamine based crystalline, porous polymers in water is investigated for the first time. Facile access to the Schiff base reaction in water has been exploited to synthesize stable porous structures using the principles of Dynamic Covalent Chemistry (DCC). Most credibly, the water-based Covalent Organic Frameworks (COFs) possess chemical as well as physical properties such as crystallinity, surface area and porosity, which is comparable to their solvothermal counterparts. The formation of COFs in water is further investigated by understanding the nature of the monomers formed using hydroxy and non-hydroxy analogues of the aldehyde. This synthetic route paves a new way to synthesize COFs using a viable, greener route by utilization of the DCC principles in conjunction with the keto–enol tautomerism to synthesize useful, stable and porous COFs in water.

Chitosan Schiff Base

In this paper, a new kind of chitosan schiff base and its zinc complexes were prepared. Chitosan schiff base (CS-DBSB) was obtained when 3, 5-Di-tert-butyl salicylaldehyde was introduced to the C-2 nitrogen position of chitosan. Its zinc complex of CS-DBSB (CS-DBSB-Zn) was also prepared. The structure and performance of physicochemical characteristics of CS-DBSB and CS-DBSB-Zn were examined by FT-IR, elemental analysis, thermogravimetric (TG). The thermal behaviors of CS-DBSB and CS-DBSB-Zn were described. TG curves presented three events including water loss, decomposition of the polysaccharide generating a carbonaceous residue that burns at higher temperatures.
