A new experimental method for evaluating the detonability of fuel-air mixtures (FAMs) based on measuring the deflagration-to-detonation (DDT) run-up distance and/or time in a standard pulse detonation tube is used to rank gaseous premixed and nonpremixed FAMs by their detonability under substantially identical thermodynamic and gasdynamic conditions. In the experiments, FAMs based on hydrogen, acetylene, ethylene, propylene, propane-butane, n-pentane, and natural gas of various compositions, as well as FAMs based on the gaseous pyrolysis products of polyethylene (PE) and polypropylene (PP) are used: from extremely fuel-lean to extremely fuel-rich at normal temperatures and pressures.

AbstractSupported polyoxide catalysts on the base of Mo and W, as well as natural Kazakhstan's clays were tested in the process of oxidative conversion of propane and propane-butane mixture. The influence of reaction temperature, contact time, composition and percentage of the active component of catalyst were determined. The important petrochemical products - acetone (500-550°) and acetaldehyde (300-350°) were the main liquid products of reaction on natural Kazakhstan's clays and also on clays modified by Mo, Bi, Cr and Ga ions.

Propane Butane

Introduction Volatiles are easily accessible and widely used in a form of liquid petroleum gas. Death as a consequence of inhalation of volatiles can be either accidental or suicidal. Case Outline We present a 62-year-old men who committed suicide by placing a plastic bag over the head and inhaling propane-butane mixture from a domestic gas tank. A rubber hose was attached to the tank valve and connected with the plastic bag. The body of the deceased showed signs of advanced postmortal changes. A suicidal note was found at the scene. Conclusion Propane-butane mixture, i.e. liquified petroleum gas leads to the depletion of oxygen in the air consequently causing hypoxia and anoxia, and therefore, unconsciousness and eventual death. The mechanisms of death in cases of volatile inhalation include cardiac arrhythmias, reflex cardiac vagal inhibition, and/or central nervous system depression. Similar mechanisms occur in cases of asphyxiation with a plastic bag. The reconstruction of the event in this case was based, not so much on autopsy findings (because of significant putrefaction changes), but on the police investigation and traces found at the scene. .

The development of technologically efficient and economical methods of using liquid pyrolysis products is a task of current interest. Despite the apparent variety of developments, the proposed methods are reduced either to obtaining a set of fractions, which are subsequently used as technical products, or to obtaining a wide range of individual compounds. The complexity and wastelessness of oil refining and petrochemistry, which has become especially acute due to the increasing negative impact of human activities on the environment, provides for the complete utilization of all material flows with the maximum extraction of useful components, the use of technologies, catalysts and reagents that exclude the formation of harmful emissions and waste. Currently, one of the most common methods for producing lower olefins (ethylene, propylene, butylenes) is the pyrolysis of hydrocarbons of various origins (gas, straight-run gasoline, a broad fraction of light hydrocarbons, etc.).

The threat of people as a result of delivery vehicle fire handling 11 kg and 33 kg bottles with propane-butane, due to leakage of these bottles was estimated. The probability of unsealing LPG bottles with gas during the year at loading, unloading and transport operations in carrier trade company was determined. Partial and total risk of serious driver injuries and the risk of death in the event of a fire in open load-carrying body of the car and tire damage was estimated. The risk assessment uses the methods of the event and fault tree as well as the probabilistic method.
