Preparation of mesophase pitch by aromatics-rich distillate of naphthenic vacuum gas oil
Two aromatics-rich distillates R1 and R2 with different properties from naphthenic base vacuum gas oil were used for preparing mesophase pitch through high-pressure thermal treatment. 1H-NMR, FT-IR and VPO were employed to characterize the structural parameters of the raw materials. The products' optical texture and molecular structure were analyzed by polarized light optical microscopy, 1H-NMR...
متن کاملBaking Powder
A mixture of powdered compounds added to dough or cake mixture to make it rise in cooking. It is used as a substitute for yeast in bread-making. Baking powders consist of a source of carbon dioxide, such as sodium hydrogencarbonate or ammonium hydrogencarbonate, and an acidic substance such as calcium hydrogenphosphate, potassium hydrogentartrate (cream of tartar), or sodium hydrogenphosphate. ...

Objectives-To assess the exposure to enzymes and prevalence of enzyme sensitisation in the baking industry. Methods-A cross sectional study was conducted in four bakeries, one flour mill, and one crispbread factory. Sensitisation to enzymes, flours, and storage mites was examined by skin prick and radioallergosorbent (RAST) tests. 365 workers were tested. The workers were interviewed for work r...
متن کاملFeasibility of In-situ Combustion of Tar from a Tarmat Reservoir
Combustion-tube tests were conducted on a tar of physical and chemical characteristics similar to a natural reservoir tar. Ottawa sand of 20-30 mesh size was used to prepare tar-sand mixtures of about 37% porosity, 19 to 25% water saturation and 21 to 32% tar saturation. In runs with distilled water, a combustion front was successfully initiated and moved into the sand pack. Later, however, the...
متن کاملProduction of Mesophase Pitch from Coal Tar and Petroleum Pitches using Supercritical Fluid Extraction
Supercritical fluid extraction (SFE) is currently being investigated as a possible technique in the production of high quality mesophase pitch from coal tar and petroleum pitches. Mesophase pitch is used to make high technology products, such as carbon fibre. The conventional production of mesophase pitch initially involves the removal of low molecular weight species from coal tar and petroleum...
