Biodiesel – the Clean, Green Fuel for Diesel Engines Abstract: Natural, renewable resources such as vegetable oils, animal fats and recycled restaurant greases can be chemically transformed into cleanburning biodiesel fuels (1) . Just like petroleum diesel, biodiesel operates in combustion-ignition engines. Blends of up to 20% biodiesel ( mixed with petroleum diesel fuels) can…

BIODIESEL AN ALTERNATIVE VEHICLES FUEL, ANALYTICAL VIEW Introduction Transesterification of a vegetable oil was conducted as early as 1853, by scientists E. Duffy and J. Patrick, many years before the first diesel engine became functional(1). Rudolf Diesel’s prime model, a single 10ft (3 m) iron cylinder with a flywheel at its base, ran on its…

Coastal protection with BMS, the first experience in Italy Abstract: The paper deals with the first Italian project of a new coastal protection system, consisting in draining the emerged beach face (BMS). The system was built in Ostia starting from December 2000 and was working since February 2001. The BMS (Beach Management System) can be…

Co-current and Counter Current Operations for Steam Reformin ABSTRACT Hydrogen production by steam reforming of higher hydrocarbon over nickelsupported catalyst is investigated in an earlier suggested novel Circulating Fast Fluidized Bed Membrane Reformer (CFFBMR). Palladium hydrogen membranes are used with co-current and counter-current operation modes. It is found that hydrogen production has a non-monotonic dependence…

Corrosion Inhibition Properties of Some Novel N-Methyl Dieth   ABSTRACT: A series of novel cationic surface-active agents containing two hydrophobic chains were evaluated for their corrosion inhibition efficiency at different doses using the weight loss method at 25oC. The applicability of these inhibitors for mild steel was examined using (4M HCl) at 50, 100 and…

  CORROSION PREVENTION AND CONTROL IN HIGH PRESSURE OIL AND GAS TRANSMISSION PIPELINES INTRODUCTION: At the start of the 1990s there were concerns over the increasing threat of corrosion to the integrity of high-pressure oil and gas transmission pipelines. For example: • Corrosion was the major cause of reportable incidents in North America[ 1] •…

  Diesel Catalytic Converters as Emission Control Devices. INTRODUCTION: Internal combustion engines are devices that generate work from combustion reactions. Combustion products under high pressure produce work by expansion through a turbine or piston. The combustion reactions inside these engines are not necessarily neutralizing or complete and air pollutants are produced. There are three major…

Dispersion of Waxy Gas Oil by Some Nonionic Surfactants ABSTRACT Straight chain fatty alcohols having the following number of carbon atoms C12, C14, C18 and C21 each alcohol was ethoxylated to the same of ethylene oxide content, characterized through average molecular weight and elemental analysis. The surface properties of these compounds were studied through surface…

EFFECT OF ORGANIC BINDERS ON THE QUALITY OF MANGANESE ORE SINTER FINES BRIQUETTES   ABSTRACT: Sinai Manganese Company imports the manganese ore sinter from abroad for ferromanganese alloy production. Large quantities of manganese ore sinter fines are produced in this process. These fines must be agglomerated to a suitable size in order to be reused…
