In converting different vegetable oils for the respective esters, at a minimum reaction temperature and faster rate of the fatty acids, the catalyst plays a very important role which can be changed into fatty acid esters (FAME), also known as biodiesel by transesterification reaction with methanol. Homogenous and heterogeneous catalysts have been identified as catalysts and among these catalysts. Homogeneous catalysts were chosen because it was possible to generate more biodiesel at a comparatively faster rate. As a feedstock, soybean waste cooking oil (SWCO) was used in this research work. With the help of a conventional mechanical stirrer reactor, SWCO with methanol was heated at various temperatures. As a catalyst, sodium hydroxide (NaOH) and potassium hydroxide (KOH) is used. It evaluated the effect of various parameters such as reaction temperature (60°C, 70°C, and 80°C), the reaction time of 2 hours, and loading of the catalyst (0.5 wt. %, 0.7 wt. %, and 1 wt. % KOH and NaOH). Results show that biodiesel produced from soybean waste cooking oil was within the recommended standards of biodiesel fuel. The transesterification reaction using KOH catalyst was more effective than the NaOH catalyst. The yield and conversion of biodiesel produced from SWCO by using 0.5 wt. % KOH catalysts at 60°C are 93.2 % and 96.16 % respectively while; the yield and conversion of biodiesel produced from SWCO by using 0.5 wt. % NaOH catalysts at 60°C are 91.35 % and 94.5 % respectively. Blends of 10, 20, 30, 50 and 100% by volume of biodiesel derived from soybean waste cooking oil and diesel fuel were prepared as B10, B20, B30, B50 and B100. Biodiesel blends have ASTM standards that are similar to diesel fuel, and the ORSAT apparatus has used to exhaust gas.

The use of activated carbon (AC) as a strong adsorbent was commonly used. This work deals with the study of textile industry wastewater (dye) adsorption on AC produced from Bamboo and Green coconut shell through chemical activation method. The effect of various process parameters such as the amount of adsorbents, initial concentration of dye, pH, contact time, temperature and agitation speed on percentage removal of dye on the activated carbon i.e. Bamboo activated carbon (BAC) and Green Coconut Shell Activated carbon (GCSAC) batch adsorption tests were investigated. Testing was performed for quantitative description of Langmuir and Freundlich equilibrium adsorption isotherms. Based on the experimental findings, the equilibrium was observed in 6 hours. Langmuir isotherm was the best suited for the adsorption of dye, with a maximal adsorption capacity of 142.86 mg / gm. The removal of dye by the use of BAC has been found to be greater than GCSAC.

Natural gas has been formed by the degradation of organic matter accumulated in the past millions of years. Two main mechanisms (biogenic and thermogenic) are responsible for this degradation. Natural gas is a complex mixture of hydrocarbon and non-hydrocarbon constituents and exists as a gas under atmospheric conditions. The objective of gas processing is to separate: Natural gas, Condensate, Non-condensable, Acid gases, Water. The raw gas is first treated to remove typical contaminants. Next, the treated gas is chilled, cooled and condensed to-162°C in succession using propane, ethylene and methane. Last stage is pumping LNG to storage tanks and awaiting shipment. Liquefied natural gas is used to transport natural gas over long distances, often by sea. In most cases, LNG terminals are purpose built ports used exclusively to export or import LNG. Natural gas consists almost entirely of methane (CH 4), the simplest hydrocarbon compound. India is the 14 th largest gas consumer 58 bcm (~158 mmscmd), 4th largest LNG importer 31 bcm (~82 mmscmd), Economy growing at CAGR of about 6-7% with similar growth in Energy Consumption. Government aims to significantly increase share of Natural Gas in Indian Energy basket to in coming years. Despite increase in domestic gas production dependency on imported gas to increase substantially. Pipeline network developing into a national grid needs to grow faster, connecting new markets. ExxonMobil's history in China dates back to 1892. This paper provides the present demand of LGN in India and also predicts future requirements, to help India's economic and social growth.
