A system for vaporizing and optionally decomposing a reagent, such as aqueous ammonia or urea, which is useful for NOx reduction, includes a cyclonic decomposition duct, wherein the duct at its inlet end is connected to an air inlet port and a reagent injection lance. The air inlet port is in a tangential orientation to the central axis of the duct. The system further includes a metering valve for controlling the reagent injection rate. A method for vaporizing and optionally decomposing a reagent includes providing a cyclonic decomposition duct which is connected to an air inlet port and an injection lance, introducing hot gas through the air inlet port in a tangential orientation to the central axis of the duct, injecting the reagent axially through the injection lance into the duct; and adjusting the reagent injection rate through a metering valve.

In a novel process for methanol production from low quality synthesis gas, in which relatively smaller adiabatic reactors can be operated more efficiently, some of the inherent disadvantages of adiabatic reactors for methanol production are avoided. This is done by controlling the outlet temperature in the pre-converter by rapid adjustment of the recycle gas, i.e. by manipulating the gas hourly space velocity in the pre-converter.

A carbonylation process for producing acetic acid including: (a) carbonylating methanol or its reactive derivatives in the presence of a Group VIII metal catalyst and methyl iodide promoter to produce a liquid reaction mixture including acetic acid, water, methyl acetate and methyl iodide; (b) feeding the liquid reaction mixture at a feed temperature to a flash vessel which is maintained at a reduced pressure; (c) flashing the reaction mixture to produce a crude product vapor stream.

This is a system for generating hydrogen on-board the vehicle from compressed natural gas (CNG) in select ratios to create hydrogen-enriched CNG (HCNG) fuel for use in internal combustion engines. The on-board generation of hydrogen is comprised of a reforming system of CNG fuel with direct contact with exhaust gases. The reforming system controls for production of HCNG fuel mixtures is based on specific engine operating conditions. The vehicle's engine controls and operating parameters are modified for combustion of selective ratios of HCNG fuel mixtures throughout engine operating cycle. The reforming system controls and engine controls modifications are also used to minimize combustion emissions and optimize engine performance.

This invention relates to the preparation of N-(phosphonomethyl)glycine (glyphosate) from N-(phosphonomethyl)iminodiacetic acid (PMIDA), and more particularly to methods for control of the conversion of PMIDA, for the identification of reaction end points relating to PMIDA conversion and the preparation of glyphosate products having controlled PMIDA content.

A continuous high capacity system for converting hydrocarbon-containing post-consumer waste, post-industrial waste, and/or renewable hydrocarbon feedstock into biofuels having an extruder for agglomerating particles and pressurizing them, a shredder to shred the agglomerated particles, a heating system to rapidly heat the fine particulate, a separator that receives heated solids and prevents heated vapors from leaving the system, and a filter with solids separator that receives the heated vapor and further separates microfine solids from the heated vapor forming a substantially cleaned vapor. A vapor cooling system receives the substantially cleaned vapor and using controlled pressure and controlled temperature, cools the substantially cleaned vapor to at least one hydrocarbon liquid and a gas, forming a hydrocarbon liquid for transfer to another device and/or using the gas as a fuel.
