During start-up of a continuous epoxidation of propene with hydrogen peroxide in a methanol solvent with a shaped titanium silicalite catalyst in a tube bundle reactor with a cooling jacket, cooling medium is fed at the rate for full load of the reactor with a constant entry temperature of from 20&#xb0; C. to 50&#xb0; C., methanol solvent is fed at a rate of from 50 to 100% for full load of the reactor, hydrogen peroxide is fed at a rate that starts with no more than 10% of the rate for full load and is increased continuously or stepwise to maintain a maximum temperature in the fixed bed of no more than 60&#xb0; C. and a difference between the maximum temperature in the fixed bed and the cooling medium entry temperature of no more than 20&#xb0; C., and propene is fed at a rate of from 20 to 100% of the rate for full load, increasing the feeding rate when the molar ratio of propene to hydrogen peroxide reaches the molar ratio for full load.

Process for the epoxidation of propene

Propene is continuously reacted with hydrogen peroxide in a tube bundle reactor comprising a multitude of parallel reaction tubes in the presence of a titanium silicalite catalyst arranged as a fixed bed in the reaction tubes. A cooling jacket encloses the reaction tubes, which has a feed point for cooling medium near the entry of the reaction tubes, a withdrawal point for cooling medium near the end of the reaction tubes and at least one additional withdrawal point upstream of the withdrawal point near the end of the reaction tubes. Cooling medium is fed to the feed point for cooling medium, a part of the cooling medium is withdrawn at the at least one additional withdrawal point and the remainder exits at the withdrawal point near the end of the reaction tubes.

Process and reactor for the epoxidation of propene

The invention relates to a process for purifying synthesis gas, comprising at least one stage for separating the crude synthesis gas to be treated into at least two effluents, namely a first part and a complementary part, in which the said first part is subjected to a carbon monoxide conversion stage with steam and the said complementary part is subjected to a COS and HCN catalytic hydrolysis stage, the two gas flows, namely the first part and complementary part, are then each treated separately in two stages intended to remove acid gases such as COand HS, by washing with aqueous solutions of specific amines, before a recombination stage of the two treated effluents.

A process for the generation of a syngas in an entrained-flow gasification process includes a solid, carbon-containing fuel which is introduced via burners into a reactor which also supplies the oxygen for gasification. The fuel is introduced on a burner level where the burners are arranged concentrically around the reaction chamber or in the head area. The syngas obtained is discharged from the reaction chamber via a discharge nozzle, so that the syngas is passed into a collecting chamber for cooling by addition of low-temperature gaseous, vaporous or liquid cooling agents. A quench chamber is provided between the reactor and the collecting chamber. Additional burner levels are in the quench chamber via which a fuel material of renewable fuels or biofuels is introduced into the syngas, so that the heat enthalpy of the syngas can be utilized for the endothermic gasification reaction of the biological raw material. An apparatus for this generation of synthesis gas includes several burner levels, the renewable fuel being supplied to the gasification chamber with or without water vapor or oxygen and the enthalpy of the hot syngas being utilized for the gasification of the renewable fuel.

A process for the catalytic epoxidation of olefins in the presence of a titanium containing zeolite catalyst and a polar solvent whereby the deactivation of the catalyst upon recycling of the solvent has been considerably reduced. In the process one or more nitrogen containing compounds are introduced at some stage, a solvent stream is recovered, treated to contain less than 50 wppm nitrogen in the form of organic nitrogen compounds and at least a part of it is recycled to the epoxidation step. Also disclosed is a process for the catalytic epoxidation of propene which integrates the treatment and recycle of the solvent into the workup of the reaction mixture.

A process for the continuous epoxidation of propene with hydrogen peroxide in the presence of a titanium silicalite catalyst and a methanol solvent, wherein the catalyst is periodically regenerated by washing with a methanol solvent at a temperature of at least 100&#xb0; C. and the epoxidation reaction is carried out for periods of more than 300 h between two regeneration steps.

The gasification device includes a pipe wall structure assembled of a plurality of pipe circuits enclosing in a gas tight manner a reactor space. A pressure jacket surrounds at a distance the pipe wall structure and delimits therewith a water filled interspace. All inlet conduits for supplying cooling water to individual pipe circuits pass through the jacket whereas the outlets of the pipe circuits open into the interspace. A common discharge conduit for cooling water is provided in the pressure jacket and communicates with the interspace. The pressure jacket is assembled of two parts interconnected by a releasable flange connection. All inlet conduits and common outlet conduits are attached to the upper part so as to enable the lifting of the entire pipe wall structure upon the lower part together with the upper part.

A device for cooling a stream of hot producer gas exiting from a gasification reactor operating at an increased pressure, includes a set of water spraying nozzles directed against the producer gas stream. Water feeding conduits connected to the nozzles pass through a sealing web provided between the pipe wall structure of the reactor and a separate pipe wall structure of a gas outlet connection piece provided above the discharge opening of the reactor. The geometric locations of respective nozzles are on a circle whose diameter is larger than that of the gas discharge opening and is smaller than the inner diameter of the pipe wall structure of the connection piece.
