Modified Beta Zeolite, Catalytic Cracking Catalyst and Their Preparation Method and Application
A modified β zeolite has 0.5-15 wt % of an IVB group metal element in terms of oxide on the dry basis weight of the modified β zeolite. The number of medium strong acid centers of the modified β zeolite accounts for 30-60% of the total acid amount, the number of strong acid centers accounts for 5-25% of the total acid amount, and the ratio of B acid to L acid is 0.8 or more. The ratio of the weight content of the IVB group metal element in the modified β zeolite body phase to the weight content of the IVB group metal element on the surface is 0.1-0.8. The catalytic cracking catalyst containing the modified β zeolite has good selectivity and yield of C4 olefin.

CONFIGURATION FOR OLEFINS AND AROMATICS PRODUCTION
Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into at least light and heavy fractions. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize an ebullated bed reactor. Products from the upgrading operations may be used as feed to a steam cracker.
Methods of using ionic liquids as corrosion inhibitors
Ionic liquid containing compositions may be used in the production, recovery and refining of oil and gas. In addition, they may be used to treat cooling water and/or to inhibit and/or prevent corrosion of metals.
Method for removing mercury in hydrocarbon oil
The present invention provides a method which can efficiently adsorb and remove ionic mercury and/or organic mercury contained in a hydrocarbon oil for a long period of time. The method involves bringing the hydrocarbon oil into contact with an adsorbent containing a layered silicate mineral having an interlayer charge of 0 or an interlayer charge of greater than 0 to 0.6 or less.

DETERMINING TRANSMISSION CONFIGURATIONS FOR RESOURCE BLOCK GROUPS AND PRECODING RESOURCE BLOCK GROUPS
Methods, systems, and devices for wireless communications are described Techniques described may be utilized to avoid errors caused by resource allocation calculations, which may be indicated via higher layer signaling and/or determined within DCI. A base station may transmit downlink control information indicating resource allocation types to avoid errors. In other cases, the UE and/or base station may designate a particular resource block group size to avoid the potential errors. The UE and/or base station may calculate a number of resource blocks groups for a bandwidth part and allocate the size of the resource block group based on the calculation. The UE and/or base station may conduct a comparison between a bandwidth part size and a resource block group size to determine whether to designate a different resource block group size to avoid the errors. Similar techniques may be utilized in allocating resources for precoding resource block groups.
