摘要： The present invention provides a process for the manufacture of a useful product from carbonaceous feedstock of fluctuating compositional characteristics, the process comprising the steps of: continuously providing the carbonaceous feedstock of fluctuating compositional characteristics to a gasification zone; gasifying the carbonaceous feedstock in the gasification zone to obtain raw synthesis gas; recovering at least part of the raw synthesis gas from the gasification zone and supplying at least part of the recovered raw synthesis gas to a partial oxidation zone; equilibrating the H2:CO ratio of the raw synthesis gas in the partial oxidation zone to obtain equilibrated synthesis gas; recovering at least part of the equilibrated synthesis gas from the partial oxidation zone and treating the gas to remove impurities and generate a fine synthesis gas; optionally adjusting the H2:CO ratio of at least part of the fine synthesis gas to obtain adjusted fine synthesis gas; and converting the optionally adjusted fine synthesis gas into the useful product in a further chemical reaction requiring a usage ratio; wherein the fine synthesis gas H2:CO ratio is below the usage ratio and wherein any optional adjustment of at least part of the fine synthesis gas H2:CO ratio is effective to increase the H2:CO ratio in the fine synthesis gas to a level at, nearer to or above the usage ratio; wherein the H2:CO ratio of the raw synthesis gas fluctuates during operation of the process as a result of the fluctuating compositional characteristics of the carbonaceous feedstock by a percentage of ±x; and the H2:CO ratio of the equilibrated synthesis gas does not fluctuate during operation of the process or fluctuates during operation of the process as a result of the fluctuating compositional characteristics of the carbonaceous feedstock by a percentage ±y, y being a lower percentage than x.

摘要： A method for ammonia cracking comprising the partial combustion and direct decomposition of ammonia directly on the catalyst in the same location and at the same time, thereby avoiding flame combustion. The control of a catalytic combustion is easier than a flame combustion and improves the control of the reaction by limiting the temperature and its variations.

摘要： The present disclosure relates to a pressure swing adsorption apparatus for hydrogen purification from decomposed ammonia gas and a hydrogen purification method using the same, and more particularly, the pressure swing adsorption apparatus of the present disclosure includes a plurality of adsorption towers including a pretreatment unit and a hydrogen purification unit wherein the adsorption towers of the pretreatment unit and the hydrogen purification unit are packed with different adsorbents, thereby achieving high purity hydrogen purification from mixed hydrogen gas produced after ammonia decomposition, making it easy to replace the adsorbent for ammonia removal, minimizing the likelihood that the lifetime of the adsorbent in the hydrogen purification unit is drastically reduced by a very small amount of ammonia, and actively responding to a large change in ammonia concentration in the raw material.
Additionally, a hydrogen purification method using the pressure swing adsorption apparatus of the present disclosure physically adsorbs and removes impurities such as moisture (H2O), ammonia (NH3) and nitrogen (N2) included in mixed hydrogen gas produced after ammonia decomposition below extremely small amounts, thereby achieving high purity hydrogen purification with improved selective adsorption of moisture, ammonia and nitrogen and maximized hydrogen recovery rate and productivity. In addition, since the temperature swing adsorption process is not introduced, there is no need for a heat source for regeneration, thereby reducing the driving cost.-

摘要： A process for producing methanol from an adjusted make-up gas comprising the steps of adjusting the stoichiometric number of the make-up gas fed to the methanol loop with a first stream of hydrogen recovered from a minor portion of makeup gas separated from the main stream, and a second stream of hydrogen recovered from the loop purge; the process further comprises the step of feeding at least a portion of a tail gas rich in methane to a reforming stage for use as a feedstock to produce the make-up gas.
