摘要:
A process for alkylating isoparaffin hydrocarbons with olefin hydrocarbons for production of high octane gasoline range alkylate wherein the alkylation reaction is performed in the presence of a sulfuric acid alkylation catalyst containing from about 0.0005 to about 0.5 weight percent of a selected micelle forming amphiphilic compound, and wherein the reaction is carried out in a non-backmixed tubular reactor.
摘要:
The heating value of solid fuel is increased and the particle size decreased by passing a slurry of the fuel in liquid water at a temperature between 400.degree. F. and the critical temperature of water through a tubular attrition under conditions of turbulent flow. The product slurry is suitable for pipelining.
摘要:
Process for making low sulfur oil by reacting aqueous reactive sludges and slurries with hot, pressurized carbon monoxide and hydrogen (synthesis gas) wherein the wastes are first concentrated by coking in the liquid phase under a pressure of 300 to 3000 psig at a temperature of 400.degree. to 550.degree. F for from 5 minutes to 2 hours.
摘要:
Improved alkylation reactor and reaction emulsion phase separation apparatus is described. Such apparatus is particularly useful in sulfuric acid catalyzed alkylation of isoparaffin with olefins for production of high octane value alkylate.
摘要:
Disclosed herein is a process for disposing of aqueous sewage and for producing fresh water by coking the sewage in the liquid phase to form gases, coke and an effluent which is extracted with a hot liquid hydrocarbon to form a hydrocarbon-water solution and a hot concentrated brine. The hot brine is injected into the sewage sludge to heat same to coking temperature. Hot water is removed from the hydrocarbon-water solution, used for space heating or the like and thereby cooled. The cool water then is passed through a carbon absorber to remove traces of hydrocarbon dissolved therein, and chlorinated to give potable water.
摘要:
The liquid phase coking of waste kraft pulping liquors can be effected with a shorter residence time in the coking means at lower temperature, and lower pressure by reducing the pH of such liquors by at least one pH unit before coking. Products are lower in malodorous organic sulfur components than those produced at a higher pH.The lowering of the pH is achieved by adding sulfur dioxide to the liquor either as free SO.sub.2 or as an aqueous solution of SO.sub.2.
摘要:
Disclosed is a process for making a hydrocarbon coke slurry fuel by coking carbonaceous materials in the liquid phase under autogenous pressure to form coke which is then extracted with a combustible hydrocarbon at high temperatures and pressures to produce a dense slurry of coke in the hydrocarbon suitable for use as a fuel.

Water is removed from carbonaceous materials such as coal by treatment with a hydrocarbon at elevated temperatures and a pressure sufficiently high to maintain the system liquid.
摘要:
A method for recovering energy from a geothermal reservoir in which brine from the reservoir is first employed to heat an immiscible fluid, such as a hydrocarbon in direct heat exchange and the heated hydrocarbon is then utilized in direct heat exchange to heat a second fluid, such as boiler feed water, to raise steam as the actual working fluid in the power cycle.
