TL;DR: It was found that the grafted raw bagasse would be most suitable for applications where oil is to be removed from an aqueous environment and this grafted bagasse had little affinity for water and good affinity for oil.

TL;DR: The catalytic effect of copper cobaltite, CuxCo3 − xO4 spinels in the range (0 ≤ x ≤ 3) on the thermal decomposition of ammonium perchlorate (AP) was studied using thermogravimetry (TG) and differential thermal analysis (DTA) as discussed by the authors.

TL;DR: Oxidative coupling of CH4 forming C 2H6 and C2H4 proceeded smoothly upon contact with Na2O2, BaO2 and SrO2 at low temperatures below 673 K, indicating that O22− ions are very reactive for activation of CH 4.
Abstract: Oxidative coupling of CH4 forming C2H6 and C2H4 proceeded smoothly upon contact with Na2O2, BaO2, and SrO2 at low temperatures below 673 K. This indicates that O22− ions are very reactive for activation of CH4. O2− ions contained in the peroxides did not activate CH4.

TL;DR: Sulfated zirconia catalysts were characterized by FT-IR, XRD, TEM and BET measurements as discussed by the authors, which revealed that among different catalysts, 10% SO 4 2− supported onto zirconsia showed the highest catalytic activity with 83% conversion and 100% selectivity toward dimethyl ether.
Abstract: Sulfated zirconia catalysts were prepared by wetness impregnation of zirconium hydroxide with an aqueous solution of (NH 4 ) 2 SO 4 with SO 4 2− loadings (1–30%, w/w) and calcined at 450 °C for 3 h in a static air atmosphere. The catalysts were characterized by FT-IR, XRD, TEM and BET measurements. The surface acidity of the catalysts was investigated by the dehydration of isopropanol and the adsorption of pyridine (PY) and 2,6-dimethyl pyridine (DMPY). The catalysts were tested for dehydration of methanol in a fixed-bed reactor at 230 °C using air as a carrier gas. The results revealed that among different catalysts, 10% SO 4 2− supported onto zirconia showed the highest catalytic activity with 83% conversion and 100% selectivity toward dimethyl ether. A good correlation was found between the acidity of the catalysts and their ability to dehydrate methanol.

TL;DR: This analysis synthesis and design of chemical processes helps people to read a good book with a cup of tea in the afternoon, instead they juggled with some harmful virus inside their desktop computer.
Abstract: Thank you for downloading analysis synthesis and design of chemical processes. Maybe you have knowledge that, people have search numerous times for their chosen readings like this analysis synthesis and design of chemical processes, but end up in infectious downloads. Rather than reading a good book with a cup of tea in the afternoon, instead they juggled with some harmful virus inside their desktop computer.

TL;DR: In this paper, a possible route is oxidative dimerization of methane followed by oligomerization of the C2 products, which can be used as feedstock for the production of chemicals or liquid fuels.
Abstract: Natural gas is an abundant resource in various parts of the world. Methane is the major component of natural gas, often comprising over 90 mol% of the hydrocarbon fraction of the gas. Methane itself is primarily used as a fuel, while the nonmethane components can be separated and used as feedstocks for the production of chemicals or liquid fuels. In many cases, however, natural gas reserves are found in locations distant from their place of utilization. Since it is not generally economical to transport liquefied natural gas, efficient methods are needed to convert methane into transportable liquid products. A possible route is oxidative dimerization of methane followed by oligomer-ization of the C2 products.
