The embodiments herein provide a filter for cigarette comprising graphene nano-composite based material enclosed in a casing. The filter is reusable and is plugged to any cigarette, or tobacco smoking products. The filter is a stand-alone product or manufactured integrally with each individual cigarette. The filter provides a safe smoking option to tobacco smokers without changing their smoking habits by reducing the tar content and other toxic chemicals in the inhaled smoke. The graphene based nanocomposite filter adsorbs the toxic agents from the smoke of cigarette, beedi, hookah. The filter is fabricated by treating ceramic particles and coating them with carbon particles. The carbon particles are carbonized. The ceramic particles coated with carbon are segregated based on shape and size and treated chemically to convert carbon into graphene under inert conditions. The graphene coated particles are chemically functionalized for improved filtration.

A method for preparing dimethyl ether (DME) from synthesis gas, wherein an input, which is formed using shifted and/or non-shifted synthesis gas, undergoes a catalytic conversion, thereby forming a product stream. The product stream undergoes a first separation, wherein a gas mixture is formed by at least partial separation of methanol and/or water from the product stream, and the gas mixture is partially condensed at a first pressure level by means of cooling from a first to a second temperature level. A portion of the gas mixture remaining in gaseous form at the second temperature level is washed in an absorption column with a return predominantly containing dimethyl ether, wherein a dimethyl ether product is formed using the portion of the gas mixture condensed during cooling.

A TPC—OTBS n-hexane solution is added to a mixture of TPC—OSO.sub.2F, DMF, and DBU and allowed to stand to produce a crosslinked solvent gel; the crosslinked solvent gel is added to methanol, stirred, and dried to produce the porous crosslinked material. The gel acquired can be prepared into a pore-rich solid porous organic polymer material by means of solvent exchange. SEM and TEM are used to characterize the surface and internal morphologies of the solid material, and the porous morphology thereof is discovered, with large pores being the majority. Infrared and nuclear magnetic resonance are used to characterize the structure of a crosslinked polysulfate; the complete reaction of a sulfuryl fluoride group is proven by means of solid-state fluorine nuclear magnetic resonance spectroscopy and XPS element analysis; and the porous structure of the crosslinked polysulfate allows same to be provided with improved application prospect in terms of adsorption.
