The application of CO2 into a valuable asset is a major concern. The generation of syn gas and then usage of the syn gas into liquid fuel, seems to be one of the promising options in terms of industrial employment, as it offers several advantages: (a) reduction of CO2, (b) conversion of gases, specially bio-gas, natural gas, LPG, and etc. and CO2 into syngas (c) producing syngas with H2/CO2 ratio 1:1.9 to 1:2.1 which may further be used for the generation of valuable petrochemicals. The present research focusses on the gas to liquid conversion using the simulating software, Aspen Plus ®. The outcomes are then subjected to Design Expert ® for calculation of the optimal generation rate. The feedstocks used for the proposed present examination are bio-gas or pyro-gas, natural gas and LPG. The research scheme, gas to liquid conversion is carried out using three steps: (a) gas (feedstock) to syngas from the combination of dry reforming and steam reforming of methane, (b) Fischer Tropsch process to produce long chains of hydrocarbons and (c) usage of unconverted CO and H2 and other alcohol derivates in the CHP unit for the production of electricity. Amongst all the feedstocks natural gas production or generation is maximum followed by bio-gas or pyro-gas and then LPG. Due to non-available resources of natural gas and generation of GHG emission, for countries like India, bio-gas or pyro-gas can be used as a promising sustainable feedstock for reducing GHG emission and global warming. The outcomes of Aspen Plus ® of biogas or pyro-gas are then subjected to Design Expert ® for the prediction of the maximal production. It can be confirmed that with 6997.54 kg/h of biogas flowrate and 99.39% recycling of CO2, the production of green gasoline, green diesel and green waxes are 565.24 (kg/h), 545.45(kg/h) and 642.68 (kg/h) respectively. The outcomes are in good agreement with the theories, thus proving the process to be a realistic one in nature. Therefore, bringing its viability for India in terms of reduction in CO2 emission and development of gas to liquid conversion process.

Kinetic parameters for the pyrolysis of jute wastes have been determined in the temperature range of 400-900 o C. A fixed bed reactor model has been developed using the kinetic parameters determined during the present study and the literature data on secondary tar cracking reaction.

Waste conversion or extraction of values from waste can proceed in various ways. In recent times, various thermochemical and biological methodologies have been applied. Amongst all the thermochemical processes, pyrolysis is gaining importance because it can be conducted according to the coveted result. The recent investigation uses swine manure and goat manure as a waste resource. The recent investigation involves the simulation of the pyrolysis plant using the Aspen Plus® process simulation software. It can be inferred that the simulated results are incomparable range with the experimental results for the lab-scale. Then with the same designed model, feed rates of 1 ton/day (TPD), 2tons/day (TPD), and 3 tons/day (TPD) manure were utilized to obtain the production of pyro-products for pilot-plant-scale. The parametric sensitivity and optimization of the simulated model have been conducted using Design Expert®. It is observed that the minimum pyro-char production, maximum pyro-oil, and pyro-gas production is obtained at 0.679232 tons/day and 0.790000 tons/day for swine and goat manure, respectively, when the manure flowrates are 2.000000 tons/day at temperature 800 K for both the manures respectively.

The main aim of this study was to develop a validated bio-analytical method (as per US-FDA and EMA guidelines) for in vivo pharmacokinetic and bioequivalence study of azelnidipine in human plasma by LC-MS/MS, API-4000. In this method, the drug was ionized in negative mode and gave adequate response because this drug was highly sensitive and had high electron affinity due to the presence of the electron-withdrawing the nitro group in the structure of azelnidipine. The deprotonated precursor ions [M-H]- at mz-1 581.2 and consistent fragment ion selected was mz-1 491.0. For internal standard, the deprotonated precursor ions [M-H]- at mz-1 269.0 (highest peak) was observed in Q1 MS and characteristic product ions or fragment ions found in Q3 MS were at mz-1 169.8. For plasma extraction, the liquid-liquid extraction technique was used. The calibration concentrated points of azelnidipine were 0.15 to 10.00 ng mL-1 includ...

The main objectives of the research are to find out the complete research trend on the national tree of India so far and to validate its traditional uses along with the pharmacological hepatoprotective activity of Ficus benghalensis L. by developing three in vitro experimental models. Methods The fruit of the said plant (F. benghalensis) was extracted with different solvent (petrochemical ether, chloroform, ethyl acetate, ethanol, water) system and the yield value was determined. Phytochemical screening was also done with a different solvent. In an in-vitro study, the liver of freshly slaughtered goat (Capra Capra) was used for various investigational tests, and the hepatotoxicity was induced by carbon tetrachloride (CCl4) at a dose of 2 ml/kg, Acetaminophen at a dose of 7 g/kg, and with Erythromycin at a dose of 1.4 g/kg.

Aluminium Oxide (Al₂O₃) was used as the catalyst. Alumina was pre-calcined at 120ºC for 2 hr in muffle furnace before being used in the reactor. Catalyst and jute were mixed directly at the ratio of 1:10. Non-catalytic pyrolysis of jute sample was conducted in the pyrolser in using the same temperature range. The use of Al₂O₃ catalyst led to higher tar yield and phenolic compounds are increased in liquid products, compared to non-catalytic pyrolysis. Catalytic pyrolysis involves the production of upgraded liquids in a single step within short residence times. The simulated results of the model were compared with the experimental results satisfactorily.
