This proposed study aims to characterize and utilize the biogas (BG) derived from the anaerobic co‐digestion of university hostel food waste and Vinasse (waste from the sugarcane industry) in a digester and to run an agricultural diesel engine with BG and Jatropha Curcas methyl ester (JCMS) on a dual fuel (DF) mode. In DF mode, BG from food waste was the main fuel, and JCMS100 was the pilot (secondary) fuel. The engine was run at different BG flow rates as 4, 8, and 12 liters per minute (LPM) with JCMS100 as injected fuel. As per the author's earlier experimental findings, the fuel injection pressure for the JCMS100 was elevated to 240 bar from the base range of 200 bar to enhance the engine performance. The experimental findings for the JCMS, and BG operation were compared with diesel in all aspects. It was revealed that the NOx emission of JCMS100 + 12 LPM of BG was about 7.5% lower than the D100 fuel at full load. Increasing BG intake up to 8 LPM, the BTE increased, however, afterward it started to decline. In a similar consequence, the brake specific fuel consumption (BSFC) declined up to 8 LPM of BG, however, when the engine was fed with 12 LPM of BG the BSFC started to elevate. The carbon monoxide and hydrocarbon also elevated with higher induction of BG. However, interestingly a NOx‐smoke compromised tradeoff was observed for JCME‐BG operation.

Burning fossil fuels releases toxic gases into the environment and has negative effects on it. In this study, Persian gum@Graphene oxide (Pg@GO) was synthesized and used as a novel adsorbent for CO2 capture. The characterization of materials was determined through XRD, FTIR, FE-SEM, and TGA analysis. The operating parameters including temperature, Pressure, and adsorbent weight were studied and optimized by response surface methodology via Box–Behnken design (RSM-BBD). The highest amount of CO2 adsorption capacity was 4.80 mmol/g, achieved at 300 K and 7.8 bar and 0.4 g of adsorbent weight. To identify the behavior and performance of the Pg@GO, various isotherm and kinetic models were used to fit with the highest correlation coefficient (R2) amounts of 0.955 and 0.986, respectively. The results proved that the adsorption of CO2 molecules on the adsorbent surface is heterogeneous. Based on thermodynamic results, as the value of ΔG° is − 8.169 at 300 K, the CO2 adsorption process is exothermic, and spontaneous.
